48V/80V LiFePO4 Forklift Batteries | Traction Wholesale OEM

Class I counterbalance forklifts run multi-shift operations where the battery is a production asset, not an accessory. A 48V 560Ah or 80V 560Ah LiFePO4 traction pack replaces a lead-acid tray that needed watering, equalizing, and swap-outs — with opportunity charging during breaks and consistent power through the full discharge curve. This page maps forklift class to voltage, explains what traction-grade packs must get right (ballast, CAN integration, opportunity charging), and details wholesale and OEM/ODM sourcing for forklift dealers, fleet operators, and equipment distributors.

Forklift Class → Voltage → Battery Map

Forklift buyers specify by truck class first, battery second. The voltage follows the class:

Forklift class	Type	Typical voltage	Typical LiFePO4 pack	Energy
Class I	Counterbalance (sit-down)	36V / 48V / 80V	36V 600Ah / 48V 560Ah / 80V 560Ah class	~20–45kWh
Class II	Narrow aisle / reach	36V / 48V	36V–48V 400–600Ah	~15–30kWh
Class III	Walkie / pallet jack	24V	24V 20–200Ah	0.5–5kWh

This page covers Class I counterbalance traction packs — the large-format segment. For Class III walkie and pallet-jack batteries, see our 24V material-handling battery page.

36V Packs: A Confirmation-Led Platform

The voltage map above splits the range three ways: 24V is the Class III walkie and pallet segment (covered by the series page linked above), 48V and 80V are the mainstream Class I platforms this page is built around — and 36V sits between them, on lighter Class I counterbalance trucks and most Class II reach trucks. 36V is not a catalogue pick; it is the platform where confirmation matters most, for three reasons:

Mixed-age fleets: 36V trucks span several decades of production. Two trucks carrying the same badge and the same nominal voltage can have different tray dimensions, connector positions, and controller voltage windows — the battery data plate and the tray measurements decide, not the model name.
Communication varies: newer 36V trucks expect CAN data from the battery; many older units predate battery communication entirely and read charge state from a simple gauge circuit. Which one your truck expects is a confirmation item, not an assumption — it changes the BMS configuration.
Charger profile: a 36V lithium pack (38.4V nominal) needs a lithium-profile charger set for the 36V platform. A lead-acid 36V charger carried over from the old fleet is not interchangeable — the charger model and its charge profile are confirmed before the pack is quoted.

The confirmation itself is the same six-point fitment check used for 48V/80V trucks — exact model and year, battery data plate, tray measurements and photos, communication protocol, charging plan, duty cycle — run per truck. Send those six items for a 36V truck and the quotation comes back engineered for that truck, on the same basis as the 48V/80V range.

Why Lithium Wins in Multi-Shift Forklift Operations

Opportunity charging: lithium accepts charge at any state of charge with no memory effect. Trucks top up during operator breaks and shift changes — 15-minute fast-charge windows replace battery swap-outs. One battery per truck per day, not two or three.
No battery room: lead-acid multi-shift operations need spare batteries, swap equipment, watering stations, and ventilated charge rooms. Lithium eliminates the entire infrastructure line from the facility budget.
Consistent power: lead-acid voltage sags as it discharges — the truck slows down in the last hours of a shift. LiFePO4 holds voltage flat through ~95% of discharge, so the last pallet moves as fast as the first.
Zero maintenance: no watering, no equalization charges, no acid spills, no terminal corrosion cleanup. The maintenance labor line goes to zero.

Opportunity Charging vs Battery Swapping

Multi-shift lead-acid fleets run on swapping: a depleted tray comes out, a charged tray goes in, and the removed battery spends the next shift on charge. Lithium fleets run on opportunity charging instead — the pack stays in the truck and tops up whenever the truck is parked. The two models differ in almost every line of the operating budget:

	Opportunity charging (LiFePO4)	Battery swapping (lead-acid model)
Batteries per truck	One fixed pack	Two to three trays in rotation
Charging location	Break areas and parking points near the work	A dedicated, ventilated battery room
Shift-change downtime	None planned — the truck charges while the operator is on break	A swap event at every battery change, plus queueing at peak times
Daily labor	Plug in, unplug	Swap handling, watering, equalization, and battery-room upkeep
Infrastructure	High-current chargers sized for simultaneous top-ups	Swap equipment, spare trays, watering and ventilation systems
Fits best when	Trucks park predictably for breaks across the shift pattern	The rooms and spare trays already exist and utilization is single-shift

The decision rule is the break pattern. If your trucks accumulate regular parked time across a shift — meal breaks, shift handovers, loading waits — opportunity charging converts that idle time into range, and the swapping infrastructure becomes unnecessary. If a truck genuinely runs near-continuously with no predictable parked windows, the honest answer is a larger-capacity pack sized for the full duty cycle, quoted against the measured duty cycle — not a swap plan rebuilt around lithium.

What Traction-Grade Packs Must Get Right

1. Ballast and tray fit

Lithium is roughly one-third the weight of the lead-acid it replaces — but a counterbalance forklift needs that weight for stability. Traction packs must be engineered with the ballast built back in: steel ballast plates or a weighted enclosure that restores the original counterweight. Tray dimensions, mounting points, and connector position must match the truck. This is per-truck engineering — quote against tray drawings, never as an off-the-shelf SKU.

2. CAN bus integration with the truck

Modern forklifts (Toyota, Linde, Hyster, Crown, Yale and similar platforms — named for fitment research only, no affiliation implied) communicate with the battery over CAN bus: state of charge on the dash, fault codes, charge interlocks. The BMS firmware must speak the truck’s protocol. Specify the truck make and model at quotation — protocol matching is project work.

3. Cell consistency at scale

A 48V 560Ah pack is dozens of large-format cells in series-parallel. At this scale, cell-to-cell voltage and internal-resistance matching is the reliability bottleneck — one weak cell degrades the whole string. Fleet buyers should ask for the cell-matching specification and the factory’s consistency data, not just the headline capacity.

4. Charger pairing and infrastructure

Opportunity charging needs the right charger: high-current 48V/80V lithium chargers (100–200A class) with the correct connector (REMA, Anderson, or machine-specific). One charger per truck for opportunity charging, or a smaller charger pool for overnight-only operations. Size the electrical supply for simultaneous charging — a 10-truck fleet on opportunity charging is a serious electrical load.

5. Thermal and environmental rating

Forklifts work in freezers, foundries, and wash-down food plants. Confirm the pack’s operating temperature range, enclosure IP rating, and whether cold-storage or high-ambient variants are needed. Standard packs cover ambient warehouses; extremes are project variants.

Brand Fitment: What Gets Confirmed for Your Truck

Forklift brands build their electric counterbalance ranges on a small set of standard voltage platforms — but tray dimensions, ballast weight, connector position, and CAN protocol are set by the exact model, not the brand. Brand names below identify truck platforms for fitment research only; LJY Energy is not affiliated with or endorsed by these manufacturers, and no pack is quoted as “compatible” with a model until the checks under the table are complete.

Truck platform (examples)	Voltage classes in the public electric counterbalance range	Confirmed per exact model before quoting
Toyota — Core and 8 Series electric counterbalance	36V / 48V / 80V	Tray dimensions, ballast weight, connector, CAN protocol
Hyster / Yale — electric counterbalance ranges	36V / 48V / 80V	Tray dimensions, ballast weight, connector, CAN protocol
Crown — FC / SC electric counterbalance	36V / 48V	Tray dimensions, ballast weight, connector, CAN protocol
Linde / Jungheinrich — E / EFG electric counterbalance	48V / 80V	Tray dimensions, ballast weight, connector, CAN protocol

The fitment confirmation we run for every truck, before any price is quoted:

Exact truck model and year — the same brand badge covers several tray sizes across generations.
Existing battery data plate — voltage, Ah rating, and the lead-acid battery’s weight (the ballast target).
Tray measurements and photos — internal length × width × height, plus the connector type and its position.
Communication protocol — whether the truck expects CAN data from the battery, and which protocol variant.
Charging plan — existing charger model, or a lithium-profile charger paired with the pack.
Duty cycle — shifts per day, break pattern, and environment (ambient, cold storage, wash-down).

Send those six items with your enquiry and the quotation comes back as an engineered proposal for your truck — not a generic pack with a brand name attached.

Fleet Buying Logic: TCO, Standardization, Reorder

TCO math: the battery costs more than lead-acid upfront; the savings are in eliminated battery rooms, eliminated watering labor, eliminated swap downtime, and one-battery-per-truck instead of two or three. Multi-shift fleets typically break even in 2–3 years.
Standardization: fleets standardize on one pack configuration across all trucks of a class — one charger type, one spares pool, one training program. Mixed packs multiply support cost.
Phased conversion: most fleets convert highest-utilization trucks first to validate range and charging logistics, then roll across the fleet over 6–12 months.
Reorder pattern: traction packs are long-cycle consumables. A dealer who converts a 20-truck fleet owns the replacement cycle for a decade — plus the charger and accessory attach on every truck.

Frequently Asked Questions

Can a lithium pack directly replace my lead-acid forklift battery?

Electrically yes — but the tray needs the ballast engineered back in (lithium is lighter), the CAN protocol must match the truck, and the charger must be a lithium-profile unit. All three are confirmed per truck model before quoting.

How does opportunity charging change fleet operations?

Instead of swapping batteries mid-shift, trucks charge during scheduled breaks. One lithium pack per truck covers a full multi-shift day in most duty cycles — eliminating spare batteries, swap equipment, and battery rooms.

What information do you need to quote a traction pack?

Truck make, model, and year; existing battery tray dimensions and photos; shift pattern and duty cycle; operating environment; and fleet size. We return an engineered quotation with ballast, protocol, and charger specification.
