Description

Product Overview
2S 20A 8.4V Li-ion 18650 Battery BMS Charger Protection Standard /Balance Board
Description:
Product Size: 45 * 15 * 3.4mm (Standard), 48 * 20 * 3.4mm (Balanced)
Product weight: 2.9 g (Standard Edition), 3.7 g (Balanced Edition)
Charging voltage: 7.8V - 8.4V
Continuous charging current (upper limit): 10A
Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current usage)
Applicable range: Suitable for Lithium batteries with a rated voltage of 3.7 V and a full voltage of 4.2 V (including 18650, 26650, polymer lithium batteries, without limitation of the dimensions)
Standard Edition: Suitable for starting drills with currents up to 25A under 50W or ohmic loads under 168W.
Balanced version: Suitable for starting currents below 25A and below 50W drills or resistive loads below 168W, with symmetrical charging function.
Note 1: The successful start of the drill requires two 10C-20C power batteries or four 5C-10C power batteries (ordinary 18650 can not start the drill !!!).
Note 2: Strictly connect 0V, 4.2V, 8.4V according to the diagram. When you connect the battery for the first time, it must be charged before it is discharged.
Note 3: When the battery is charging, 430 resistance heating is a normal phenomenon, indicating that the equalization circuit is working; If resistance 430 heats up while charging, check if the wrong wire is connected.
For some customers with bad electronic base please explain: Do not mix good batteries and bad batteries! The capacity / internal resistance of 2 batteries should be as close as possible! (1 good battery + 1 bad battery = 2 battery use effect).
Package included:
1 * 2S 20A 18650 lithium battery protection board
