Product Details

LWS® 2S 3A Lithium ion Battery For Electrical Tool UPS BMS
The circuit board is made with high quality electronic components, stable and reliable, suitable for 2 series 3.7V 18650 Li-ion cell.

Notes

1) Wire connection strictly according to the drawing, do not intentionally short circuit.
2) Before charged, need to connect the cables first.
3) When the group of battery is 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.
