Swapping a forklift’s lead-acid battery for lithium sounds simple until you’re standing in front of the battery compartment holding a spec sheet that doesn’t quite match your truck. Toyota, Hyster, and Crown are the three brands most North American warehouses run, and each one built its electric lineup around its own voltage platforms, compartment envelopes, and connector standards. Getting a lithium replacement wrong isn’t a minor inconvenience — a battery that’s the wrong voltage won’t power the truck at all, and one that’s the wrong physical size won’t seat, balance, or lock in the compartment.
This guide walks through how voltage, dimensions, and connectors line up across Toyota, Hyster, and Crown fleets, and how BlitzNXT’s lithium forklift battery lineup maps onto each one. If you manage a mixed fleet or you’re converting your first truck from lead-acid to LiFePO4, treat this as the reference to check before you order.
Why Voltage Platform Comes First
Every forklift’s drive motor, controller, and charger are engineered around one voltage. A battery that doesn’t match that voltage isn’t a performance compromise — the truck simply won’t run, or the controller will fault out to protect itself. Before comparing connectors or compartment sizes, confirm the voltage stamped on your existing battery’s nameplate or your truck’s data plate.
Toyota’s Voltage Lineup
Toyota Material Handling’s electric counterbalance range is built primarily on 48V and 80V systems, with 24V reserved for lighter-duty equipment. Toyota’s lithium-ion batteries for forklifts are offered in 24V, 36V, and 48V versions designed to fit a range of Toyota trucks used in cold storage, food and beverage, and manufacturing applications. Toyota’s own 5/35 Lithium-Ion battery line confirms this same 24V/36V/48V spread, with capacities running from roughly 456Ah up to 912Ah depending on compartment width.
| Toyota Truck Series | Typical Application | Common Voltage |
|---|---|---|
| 8FBE (compact counterbalance) | Light-to-medium duty warehouse | 48V |
| 8FB / 8FBN (standard counterbalance) | 1.0–3.5 tonne capacity | 48V / 80V |
| 7FBR (reach truck) | Narrow-aisle, high-rack storage | 48V |
| Order pickers / pallet trucks | Horizontal and low-level order picking | 24V |
Hyster’s Voltage Lineup
Hyster spreads its electric range across four voltage tiers depending on truck class and duty cycle. The J-series counterbalance line covers the bulk of warehouse and yard applications, while heavier J-series big trucks step up to a 350-volt architecture — Hyster notes that its high-capacity J230-400XD series uses this 350-volt platform specifically to deliver combustion-engine-like performance without the cost of an even higher-voltage system, a design approach Hyster carried forward from its earlier high-capacity lithium-ion truck launches, including the J10-18XD series covered by DC Velocity.
| Hyster Truck Series | Typical Application | Common Voltage |
|---|---|---|
| J2.0XN / J2.5XN | Light counterbalance, 3,000–5,500 lb capacity | 48V |
| J40XN–J70XN | Standard counterbalance, 2.0–3.5 tonne | 80V |
| R-series (reach truck) | Narrow-aisle, high-rack storage | 48V |
| P-series / LO-series | Pallet trucks, order pickers | 24V / 48V |
| E-series | BCI-standard cushion-tire counterbalance | 36V / 80V |
Crown’s Voltage Lineup
Crown’s electrification strategy took a different path: rather than segmenting voltage tightly by model series, Crown built its V-Force lithium-ion Energy Storage System to be compatible across nearly its entire forklift portfolio. Crown’s own materials describe the V-Force system as available across the complete range of Crown forklift trucks, with a lithium-ion battery selection sized to fit each truck. The rollout started with the WP-series pallet truck before expanding fleet-wide, a sequencing confirmed by DC Velocity’s coverage of the original V-Force launch.
| Crown Truck Series | Typical Application | Common Voltage |
|---|---|---|
| WP-series (pallet truck) | Horizontal transport, order picking | 24V |
| RM / RR-series (reach truck) | Narrow-aisle, high-rack storage | 36V / 48V |
| SC / FC-series (counterbalance) | Standard warehouse and yard duty | 36V / 48V |
Key takeaway: across all three brands, 24V covers pallet trucks and order pickers, 36V and 48V cover the bulk of reach trucks and standard counterbalance trucks, and 80V (or Hyster’s 350V architecture) is reserved for heavy-capacity applications. BlitzNXT currently ships 24V, 36V, and 48V LiFePO4 packs, which puts the majority of Toyota, Hyster, and Crown fleets within reach of a direct lithium upgrade.
BlitzNXT LiFePO4 Forklift Battery Specifications
Here’s what BlitzNXT actually ships in each voltage class, built on EVE Grade-A LiFePO4 cells with a 10-year warranty across the line:
| Spec | 24V 230Ah | 36V 920Ah | 48V 608Ah |
|---|---|---|---|
| Nominal voltage | 25.6V | 38.4V | 51.2V |
| Capacity | 230Ah | 920Ah | 608Ah |
| Usable energy | ~5.9kWh | ~35kWh | ~29.2kWh |
| Dimensions (L×W×H) | 662×650×195mm | 967×738×575mm | 969×828×575mm |
| Weight | ~105kg (232 lb) | ~420kg (926 lb) | ~392kg (864 lb) |
| Standard / peak discharge | 115A / 175A | 150A / 350A | 121.6A / 350A |
| Charge/discharge interface | Anderson 175 | REMA320 / Anderson SB350 | REMA320A / Anderson 350A |
| Ingress protection | IP67 | IP67 | IP67 |
| Cycle life | 3,000+ cycles | 3,000+ cycles | 3,000+ cycles |
Two things stand out for compatibility purposes. First, all three packs use connector families — Anderson and REMA — that are the same physical standards Toyota, Hyster, and Crown trucks already use on the truck side, so the swap is a matter of confirming which specific connector variant your truck carries rather than rewiring anything. Second, every BlitzNXT unit ships in a sealed IP67 enclosure, which matters more for Toyota and Hyster trucks running in cold storage or wash-down environments where Toyota’s own lithium line is rated to a comparable IP69 standard.
Connector and Interface Compatibility
Connector mismatches are the single most common reason a “compatible” battery doesn’t actually connect. Even when voltage and physical size line up, a different pin count, housing shape, or gender on the discharge connector will stop an installation cold.
- Anderson-style connectors (SB175, SB350, and similar) are widely used across Toyota’s lighter compartments, Crown’s WP and reach-truck lines, and many aftermarket Hyster conversions. BlitzNXT’s 24V pack uses an Anderson 175, and the 36V pack offers an Anderson SB350 option.
- REMA connectors (REMA320, REMA320A) are common on higher-capacity European-influenced platforms and are frequently found on Hyster and Crown counterbalance trucks in the 36V–48V range. Both BlitzNXT’s 36V and 48V packs ship with REMA-standard connector options alongside the Anderson alternative.
- OEM-proprietary connectors: Toyota’s newest 5/35 lithium line uses a dedicated truck connector with built-in drive-away protection, and factory-integrated Hyster and Crown lithium systems use their own CAN-bus-linked connectors that communicate directly with the truck’s battery management interface. A drop-in replacement battery like BlitzNXT’s will not replicate this proprietary CAN communication — it restores power delivery, not the OEM’s telemetry layer.
If your truck currently runs a lead-acid battery with a standard Anderson or REMA connector, a BlitzNXT pack in the matching voltage and connector configuration is generally a straightforward physical swap. If your truck came from the factory with an OEM-integrated lithium system, confirm with your technician whether the truck’s controller requires CAN communication from the battery to operate, since that changes the compatibility picture.
Compartment Fit and Weight
Voltage and connectors get a battery talking to the truck; dimensions and weight determine whether it actually belongs in the compartment. Toyota publishes compartment widths from roughly 13 inches for 24V trucks up to 36 inches for its largest 48V platforms, and Hyster and Crown follow similar scaling by voltage class and truck size. Because BlitzNXT’s packs are engineered as drop-in replacements sized to standard forklift battery compartments, the dimensions in the table above should be checked against your specific compartment opening before ordering — particularly on Toyota trucks, which use adjustable spacer tabs to accommodate multiple battery widths within one compartment class.
Weight matters just as much as footprint. Counterbalanced forklifts rely on battery weight as part of the truck’s stability calculation, and swapping to a lighter lithium pack without accounting for the change can affect rated lift capacity. We cover this in detail in how lithium forklift battery weight changes counterbalance, which walks through nameplate capacity checks and when added ballast is necessary.
Charging Infrastructure Compatibility
A compatible battery still needs a compatible charger. Toyota’s lithium-ion chargers support a voltage range of 24V to 90V and communicate directly with the battery’s onboard management system, while Crown’s V-Force chargers use a CAN-bus interface to communicate with the battery pack at up to roughly 97% efficiency, according to Crown’s own technology documentation. Hyster’s factory-integrated systems are similarly closed-loop, linking battery, charger, and truck telemetry into one validated ecosystem.
This closed-loop design is exactly why a drop-in replacement battery like BlitzNXT’s ships with a standard-current charger sized to the pack’s voltage and Ah rating rather than trying to replicate a proprietary OEM charging protocol. For most lead-acid-to-lithium conversions, this is a non-issue: the truck doesn’t require a CAN-linked charger to run, and a properly sized standalone charger handles the pack correctly. The exception is trucks factory-built around an OEM lithium system, where the truck’s dash display and safety interlocks are wired to expect data from that specific battery.
Fleet Compatibility Checklist
Before ordering a replacement battery for a Toyota, Hyster, or Crown truck, work through these five checks:
- Confirm nameplate voltage. Check the truck’s data plate or the existing battery’s label — never assume based on truck size alone, since Toyota, Hyster, and Crown all run multiple voltage options within the same model family.
- Measure the compartment. Record length, width, and height, and note any adjustable spacer tabs currently installed, which affect the usable dimensions.
- Identify the connector type. Photograph or physically inspect the existing discharge connector — Anderson, REMA, or OEM-proprietary — before assuming a match.
- Check for factory-integrated lithium telemetry. If your truck’s dashboard already displays lithium-specific battery data (Toyota’s CAN protocol, Hyster Tracker, or Crown’s in-truck display), confirm with your dealer whether that display requires the OEM battery specifically.
- Verify counterbalance impact. Compare the replacement battery’s weight against the original lead-acid unit’s weight, and consult your truck’s nameplate capacity rating if the difference exceeds a few percent. Our guide on Class I, II, III forklift lithium battery configuration goes deeper into how truck class affects this calculation.

Why Lithium Compatibility Matters More Than Lead-Acid Ever Did
Lead-acid battery swaps were forgiving: dimensions and BCI group sizing (a classification system maintained by Battery Council International to standardize battery physical dimensions and terminal placement) did most of the compatibility work, and voltage was the only real variable to check. Lithium changes that equation. A LiFePO4 pack’s BMS, connector standard, and communication protocol are all part of the compatibility picture now, not just its physical footprint. That’s also why battery charging and changing procedures fall under OSHA’s powered industrial truck standard, 29 CFR 1910.178 — getting the wrong battery into a compartment isn’t just a performance problem, it’s a safety one, and the standard’s charging-area and securing requirements apply regardless of chemistry.
Getting this right the first time avoids the two most expensive mistakes in a lithium conversion: ordering a battery that doesn’t physically fit, and ordering one that fits but leaves the truck’s rated capacity or safety interlocks out of spec. For fleets running standard lead-acid-compatible Toyota, Hyster, or Crown trucks, matching voltage, connector, and dimensions against the tables above should get you to a confident order. For factory-integrated OEM lithium trucks, loop in your dealer before assuming a third-party pack will talk to the truck’s existing telemetry.

FAQ
Will a BlitzNXT lithium battery work in any Toyota, Hyster, or Crown forklift?
It depends on voltage, connector type, and compartment size matching your specific truck. Standard lead-acid-compatible trucks in the 24V, 36V, or 48V range are generally straightforward swaps. Trucks with factory-integrated OEM lithium systems and CAN-linked telemetry need a compatibility check with your dealer first, since the dashboard display may expect data from the OEM battery specifically.
Do I need to change my charger when switching to a BlitzNXT lithium battery?
In most standard lead-acid-to-lithium conversions, yes — you’ll pair the battery with a charger sized to its voltage and Ah rating rather than reusing a lead-acid charger, since charge profiles differ between chemistries. BlitzNXT can advise on charger pairing based on your existing setup.
Why do Toyota, Hyster, and Crown use different connector types?
Connector standards evolved separately across manufacturers and regions — Anderson-style connectors are common on North American-influenced platforms, while REMA connectors are more common on higher-capacity and European-influenced designs. Many trucks from all three brands use one or the other depending on model year and compartment size, which is why physically confirming the connector before ordering matters more than assuming by brand.
Does switching to a lighter lithium battery affect my forklift’s lift capacity?
It can. Counterbalanced forklifts use battery weight as part of the truck’s stability calculation, so a significantly lighter lithium pack may require the compartment weight to be restored with ballast to keep the truck’s rated capacity accurate. Check your truck’s nameplate and see our guide on counterbalance weight changes for the full calculation.
Is IP67 protection necessary for a standard warehouse forklift?
Not always, but it adds a margin of safety in any environment with dust, washdown, or occasional moisture exposure — common in food and beverage, cold storage, and outdoor yard operations. Since BlitzNXT ships all its forklift batteries at IP67 as standard, it’s not an added cost consideration either way.
