4S 100A LiFePO4 BMS Battery Protection Board
LKR1000.00
A 100A 4S BMS (Battery Management System) is designed to manage four lithium cells in series, commonly for 12V LiFePO4 or 14.8V Li-ion battery packs. While specific models vary, standard specifications typically include a 100A continuous discharge current and comprehensive protection against overcharging and over-discharging.
| Feature | LiFePO4 (LFP) Typical | Li-ion (NMC/NCM) Typical |
|---|---|---|
| Nominal Voltage | 12.8V (3.2V per cell) | 14.8V (3.7V per cell) |
| Charge Voltage | 14.4V – 14.6V | 16.8V |
| Continuous Discharge | 100A | 100A |
| Peak/Instantaneous | 120A – 200A | 120A |
| Overcharge Cutoff | 3.65V – 3.75V per cell | 4.25V ± 0.05V per cell |
| Over-discharge Cutoff | 2.0V – 2.5V per cell | 2.5V – 2.8V per cell |
| Balance Current | 30mA – 70mA (Passive) | 50mA – 60mA |
