A 36V 125Ah lithium-ion battery with 38.38″ dimensions represents a high-capacity energy storage solution designed for industrial or commercial applications requiring sustained power output. Such batteries typically employ LiFePO4 chemistry for thermal stability and cycle durability, with 36V systems delivering 4.6kWh energy capacity. While standardized 36V lithium batteries in 125Ah configurations exist, the specified 38.38″ length indicates a specialized form factor, likely for integration in forklifts, solar storage racks, or custom EVs. Pro Tip: Confirm terminal placement and IP ratings when replacing legacy lead-acid batteries to ensure physical and electrical compatibility.
How Much Does a Forklift Battery Weigh?
What applications require 36V 125Ah batteries?
36V 125Ah lithium batteries power heavy-duty equipment needing long runtime and high discharge rates. Common uses include electric pallet jacks (2-4 hour shifts), solar storage buffers (8-10kWh systems), and floor-cleaning machines. Their 150-200A continuous discharge supports motors up to 5kW.

Electric forklifts particularly benefit—compared to 48V systems, 36V models offer better weight distribution in compact units. The 38.38″ length likely matches Class II/III lift truck battery trays. What if you need colder operation? LiFePO4 cells maintain 80% capacity at -20°C versus NMC’s 50% drop. For example, a 36V 125Ah pack running a 2kW motor provides 2.25 hours at 80% depth of discharge. Always verify mounting bracket compatibility—some racks need spacer kits for lithium’s reduced weight.
How does 125Ah capacity impact performance?
A 125Ah rating at 36V translates to 4.5kWh storage—triple standard 36V 40Ah scooter batteries. This enables 12-hour UPS backup for 300W loads or 45km range in 1.5-ton utility vehicles. High amp-hour batteries use paralleled cells, requiring robust BMS balancing.

Lithium’s 95% efficiency versus lead-acid’s 70% means more usable energy. But what about weight? A 36V 125Ah LiFePO4 pack weighs ~38kg—half equivalent lead-acid. However, the 38.38″ length demands precise compartment sizing. Pro Tip: Add vibration dampers if installing in mobile equipment—prismatic cells need protection from impacts.
| Chemistry | Cycle Life | Cost/Ah |
|---|---|---|
| LiFePO4 | 3,000+ | $0.85 |
| NMC | 1,200 | $0.65 |
Why is the 38.38″ dimension significant?
The 977mm length corresponds to industrial battery trays standardized for Class II forklifts. It allows 3-4 battery banks in 1m racks while maintaining undercarriage clearance. This dimension typically houses 18-24 prismatic cells in series-parallel configurations.
Equipment designers allocate specific compartments—a 0.5″ size mismatch prevents installation. For retrofits, measure tray width/height too—38.38″ batteries often pair with 19.7″ widths. Always check terminal orientation (front-left vs. rear-right) when replacing existing packs.
What safety features do these batteries require?
36V high-capacity systems mandate multi-layer protection: temperature sensors on every cell module, MOSFET-based disconnect at 32-45V range, and flame-retardant casing. Industrial applications need IP67 ratings for dust/water resistance.
Thermal runaway risks increase with large packs—certified UL1973 batteries undergo nail penetration testing. Why risk non-certified units? A 125Ah battery stores enough energy to cause thermal events if BMS fails. Pro Tip: Install battery compartments with emergency vents and Class D fire extinguishers nearby.
| Protection | Standard | Trigger |
|---|---|---|
| Over-voltage | 43.8V | Disconnects load |
| Under-voltage | 27V | Enters sleep |
How to verify compatibility?
Match four parameters: voltage tolerances (±2V), terminal type (SAE/GB/T), charge profile (LiFePO4 vs. NMC), and communication protocols (CAN/RS485). The 38.38″ length suits specific chargers with extended docking guides.
Test the battery management system’s handshake with equipment controllers—some EVs require firmware updates. For solar applications, confirm inverter compatibility with lithium’s voltage curve. Remember, even 36V systems can deliver lethal currents—always hire certified technicians for installations.

FAQs
No—lithium batteries lack electrolyte for equalization. Series connections require matched packs with unified BMS control, which we customize for specific voltage needs.
What’s the recharge time?
With 30A charger: 125Ah ÷ 30A = 4.2 hours (plus CV phase). High-current 50A units reduce to 2.8 hours but require 220V inputs.
Does cold storage damage cells?
Store at 40% charge in 0-35°C environments. Avoid temperatures below -20°C—electrolyte viscosity affects low-temperature performance recovery.
