Product Feature and Application
LWS® battery protection board 3S 4S 5S 10A 21V Lithium ion Battery Pack BMS
is used for (5S lion) high-capacity battery pack.
Product Details
3S 4S 5S 10A 21V Lithium ion Battery Pack BMS
■ Support 5S LIION Battery Pack
■ Separate monitoring of each string of cells
■ 3 groups of temperature monitoring
■ Over voltage protection (single cell, battery pack), under voltage protection (single cell, battery pack)
■ Over current protection (charge, discharge), level short circuit protection, anti-charge protection
■ Temperature protection (high temperature, low temperature)
Notes
1) Wire connection strictly according to the drawing, do not intentionally short circuit.1) Wire connection strictly according to the drawing, do not intentionally short circuit.
2) Before charged, need to connect the cables first
3) When ten groups of batteries are connected in series, ensure that the voltage of each group of batteries voltage is the same. If not, fill each group of batteries separately before connecting them in series. In discharge tests, the group of cells with the fastest voltage drop is the differential cell.
