Specifications
Status key: [Industry reference] = the base definition of this model class or an arithmetic value, not an LJY test result. [Optional configuration] = available by OEM/ODM project. [Confirmed per project] = fixed only in the datasheet issued with your quotation (cell option, BMS rating, dimensions, weight, terminals, documents). We do not publish unverified values — request the datasheet.

BMS, Communication & Protection
Every pack uses a built-in battery management system with over-charge, over-discharge, over-current, short-circuit and temperature protection plus cell balancing. The BMS current rating sets what the battery can actually deliver, so it should be chosen from the load — not from the capacity. The guide below is general engineering guidance; the BMS rating offered for your order is confirmed in the quotation.
BMS sizing guide
| Load / use case | Suggested BMS rating |
|---|---|
| Light 36V golf carts / mobility (moderate load) | 50A BMS |
| 36V trolling motors — match motor max draw | 50–80A BMS |
| Lifted carts or high-current controllers | Higher BMS or step up to 36V 100Ah |
Match the BMS to the motor controller peak current, not only to the Ah rating. Tell us the cart/motor model and controller rating. Charging: use a 36V LiFePO4 profile (about 43.2–43.8V absorption for 12S). Confirm the charger profile before installation.
Size & Fitment
Golf cart and equipment trays vary widely. Send tray measurements (L×W×H) and terminal position. Final dimensions are confirmed per project in the quotation datasheet.
36V lead-acid carts often need a DC-DC converter for 12V accessories after conversion; it can be included in the kit.
Applications
- 36V golf carts and neighborhood EVs (entry / short-range)
- 36V trolling motors
- Mobility and cleaning equipment
- Light industrial and campus vehicles
- Lead-acid to lithium conversion for 36V systems
Application limits
- Confirm controller voltage window for 38.4V lithium.
- Use a LiFePO4-profile charger.
- Range depends on load, terrain and speed — we do not publish a guaranteed range.

OEM / ODM Options
- Branding: case color, logo printing, labels, user manual and retail packaging.
- Electrical: capacity variant, BMS continuous/peak current, charge limits.
- Monitoring & communication: Bluetooth app, SOC display, RS485 / CAN where the system needs it.
- Environment: low-temperature charge protection or self-heating.
- Mechanical: enclosure size, terminals, handles, mounting and connector type.
How we help new battery brands configure this model
- 1. Define the use case: application, largest load / inverter or controller, charging sources and climate.
- 2. Pick the configuration: we map that to cell option, BMS rating, monitoring and enclosure, and flag trade-offs.
- 3. Sample stage: evaluate samples against your own tests and documentation needs.
- 4. Pilot order: confirm labeling, packaging and document package.
- 5. Repeat supply: lock the specification so reorders stay consistent.

Frequently Asked Questions
Can it replace a lead-acid battery directly?
Usually, after checking charger profile, terminal type/orientation and compartment dimensions. See our LiFePO4 vs lead-acid guide.
Are the specifications on this page fixed?
No. Values marked [Confirmed per project] are fixed only in the datasheet issued with your quotation.
Can you supply it under my own brand?
Yes — case color, logo, labels, manual and packaging are standard OEM options; electrical and monitoring changes are handled as ODM configuration.
Is a 36V LiFePO4 battery really 38.4V?
Yes. A 12-cell LiFePO4 pack has a 38.4V nominal voltage and is the standard lithium replacement for 36V lead-acid systems.
50Ah or 100Ah for a golf cart?
50Ah suits light use and short courses; most dealers stock 100Ah as the mainstream 36V cart SKU. Confirm daily range needs before ordering.
Values marked [Confirmed per project] are fixed in the order specification. Product images are illustrative renders, not photographs of production units. Content as of October 2026.
