Product Feature and Application

Our 1S 3A 5A 3.7V used for solar, LED lights, Emergency lights, Digital Equipment, etc.electric scooter,e-bike,tourisr sightseeing vehicle,electric tricycle,low speed ev,emergrncy ups,solar street light,RV&home energy storage.

Product Details

Stable and reliable performance with level A protection IC is directly from original manufacturer

High-precision 0201 size components SMT technology and lead-free.

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.
