Lithium Forklift Battery (LiFePO₄) — 24V/36V/48V, 50–690Ah

Fast opportunity charging • Stable voltage all shift • Built‑in BMS (CAN/Modbus) • Maintenance‑free

Why switch to a lithium forklift battery now?

More uptime: Opportunity charging during breaks keeps trucks available without long overnight sessions.
Stronger, steadier performance: Flatter discharge curve means lift and acceleration stay consistent late in the shift.
Lower total cost: High round‑trip efficiency and zero watering cut energy and labor overhead.
Cleaner & safer: No acid mist, no spills; built‑in BMS monitors, balances and protects cells.
Wide temperature window: LiFePO₄ chemistry and appropriate thermal design handle real‑world warehouse conditions.

LiFePO₄ vs. Lead‑acid — What changes in daily operations?

Metric	LiFePO₄ Lithium Forklift Battery	Lead‑acid Traction Battery
Charge Time	2–3 h typical with suitable fast charger; supports opportunity charging	6–8 h standard charge + cool‑down
Voltage Stability	Flatter discharge curve; consistent lift/acceleration	Voltage drops progressively with SoC
Maintenance	No watering; no equalization cycles	Regular watering, cleaning, and equalization
Cycle Life	Thousands of cycles (DoD & temperature dependent)	Hundreds to ~1,000 cycles (application dependent)
Total Cost of Ownership	Higher upfront, lower lifetime energy & labor cost	Lower upfront, higher maintenance & replacement cost
Safety & Cleanliness	Closed system; no acid mist	Acid handling and spill prevention required

Values are indicative and vary by charger power, usage profile, ambient temperature, and specific cell design.

Safety & Compliance

IEC 62619: Safety requirements for industrial lithium cells and batteries.
UN 38.3: Transport of lithium batteries (includes Test Summary for shipping).
UL 583: Electric‑battery industrial trucks (truck‑level compliance).

Request the latest certificates, reports, and shipping documents before procurement.

Integration & Charging

Built‑in BMS with CANbus/Modbus for truck CAN gateway or telemetry.
Charger matched to battery chemistry and voltage with adequate power for shift pattern.
Optional cloud dashboard: SoC, charge events, utilization, alarms.

Tip: Audit your break schedule and outlet capacity—often a small change unlocks full‑shift operation without extra packs.

FAQs: Lithium Forklift Battery (LiFePO4)

Will opportunity charging damage the battery?

With proper charger settings and BMS integration, opportunity charging is expected and helps reduce downtime without compromising life.

Can I reuse my existing lead‑acid charger?

Use a lithium‑compatible charger. Lead‑acid chargers generally do not match LiFePO₄ voltage and current profiles.

How do I choose capacity?

Base capacity on truck power draw (including hydraulics), average duty cycle, and break windows. Many fleets size for one battery per truck with opportunistic top‑ups.

What about cold storage or hot climates?

Specify a battery with appropriate thermal design. LiFePO₄ can operate in a wide range; charge acceptance at low temperatures may require pre‑heat strategies.

Which documents are needed for export?

UN 38.3 Test Summary for shipping is required. For industrial safety, request IEC 62619 reports; truck compliance typically references UL 583.

Implementation Checklist

Confirm truck class (I/II/III), voltage (24/36/48V), and required peak current.
Run a power study: charger power, break windows, number of trucks.
Verify BMS communication (CANbus/Modbus) and telemetry options.
Collect compliance docs: IEC 62619 reports, UN 38.3 Test Summary.
Pilot 1–2 trucks, validate uptime and energy cost, then scale.
