Module Li-Ion Lithium Charger Protection 3A 7.4V
This PCB protects Lithium Ion batteries configured in 2S from over-charging and over-discharging.
It also protects the cells from over-current loads, limiting the maximum output to 3A.
It also features short-circuit protection, which protects the batteries from damage in the event of a short on the output wires.
This module is NOT a charging circuit! An adequate charger must be used to properly charge your batteries.
Parameter Min Typ Max Unit
Charging Voltage - 7.4 8 V
Charging Current - - 3 A
Discharge Current - - 3 A
Overcharge detection per cell 4.32 4.35 4.38 V
Overdischarge detection per cell - 2.9 - V
In order to activate the protection module output, a charge voltage must be briefly applied to the P+/P- terminals after the batteries are connected to it.
