5S 15A 18.5v 18650 BMS Battery Protection Board Lithium Charger PCB

Electronic system 5S working as a protection of batteries against excessive unloading. This module also assures the function of the battery charger.
It allows you to build a safe battery pack that does not have to be charged with special chargers for li-ion batteries.
 The 2-in-1 module was created to keep the cells in the best possible condition, not allowing them to be overcharged or over-discharged.
Short-circuit protection.
Overcharge protection.
Overcharge protection.
Overcurrent protection.
Can be used for various 3.7V lithium cells.
Compact size and light weight.
