12.8V 100Ah LiFePO4 Battery Buying Checklist
A practical 12.8V 100Ah LiFePO4 buying checklist covering 1.28kWh nominal energy, charging voltage, current, temperature, dimensions and cycle tests.
Send an inquiry ↗For a 12.8V 100Ah battery, start with the load and charger, then check the 14.2–14.6V charge range, 100A maximum continuous current, temperature limits and installation dimensions. Read cycle life together with its test conditions.
Translate Ah into nominal energy
This model is rated at 12.8V and 100Ah, giving 1.28kWh nominal energy. Ah alone cannot compare energy across batteries at different voltages; usable energy also depends on the load and operating conditions.
Check charging and continuous load
The product list states a 14.2–14.6V charge range and 100A maximum continuous charge and discharge current. Check the charger profile, continuous load, cabling and protection as one configuration.
Confirm environment, size and test basis
The unit measures 260 × 168 × 214 mm and weighs 9.92kg net. The listed charge range is 0–55°C and discharge range -30–60°C; ≥3000 cycles uses 0.5C charge, 1C discharge, 100% DOD, 80% EOL and 25°C test conditions.
What to send with an inquiry
- Application and load current, including any peak requirement
- Charger output profile and 14.2–14.6V charge requirement
- Installation size, temperature, target market and documents
Common questions
Does 100Ah mean 1000Wh?
No. Energy depends on voltage; this 12.8V, 100Ah model is specified at 1.28kWh nominal energy.
Does ≥3000 cycles apply under every use condition?
No. The figure corresponds to the stated test conditions; real-world performance depends on the application.
