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 |
|---|---|
| Mobility, medical carts, telecom (under ~25A) | 50A BMS |
| 24V trolling motors up to ~42A max draw (70 lb class) | 50A BMS |
| Motors with 50A+ max draw (80 lb class) | Use 80–100A BMS or step up to 24V 100Ah |
For trolling motors, size the BMS to the motor maximum draw, not the average. Charging: use a 24V LiFePO4 profile (28.4–29.2V absorption, equalization off); lead-acid 24V chargers with desulfation modes are not suitable. See the charging guide.
Size & Fitment
Market designs at this size often use Group 24 or Group 31 class enclosures. If you replace two 12V batteries, one 24V unit frees a battery tray — tell us which tray it will occupy. Final dimensions, weight and terminal layout are confirmed per project in the datasheet issued with your quotation.
For equipment (AGV, cleaning machines), send the battery compartment drawing and connector type; enclosure and connector are typical ODM items.
Applications
- 24V trolling motors on small boats and kayaks
- Mobility scooters and power wheelchairs (subject to OEM approval)
- Floor scrubbers and cleaning machines
- AGVs, carts and light material handling
- Medical carts and telecom backup
- Small 24V solar systems
Application limits
- Not for engine starting.
- 80 lb+ trolling motors used hard need more capacity or higher BMS current.
- Standard version should not be charged below 0°C without low-temperature protection.

- 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. Some devices also have a low-voltage cut-off tuned for lead-acid. See our LiFePO4 vs lead-acid guide.
Are the specifications on this page fixed?
No. The exact cell option, BMS rating, dimensions and documents are confirmed 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.
Can one 24V 50Ah replace two 12V batteries?
Yes — it replaces two 12V batteries wired in series, with one BMS and one charger, as long as the charger supports a 24V LiFePO4 profile.
Is 50Ah enough for a 24V trolling motor?
For small boats and moderate use, often yes. For long days, wind/current or GPS anchoring, choose 24V 100Ah.
