The 3S 25A Li-ion Lithium Battery Charger Protection Board is a circuit board designed to protect and manage the charging of 3-cell lithium-ion batteries with a maximum current of 25A.
Description:
Suitable for starting current below 25A. 3S 12.6V 25A lithium battery protection board (comes with recovery function-AUTO Recovery)
Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Product weight: 9.8g
Charging voltage: 12.6V
Note 2: Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 3: When soldering the battery for the first time or while charging, as long as the single battery exceeds 4.2V, the "430" resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" resistor is severely hot, check if the wrong line is connected.
