0.95W 10A 20A 7.4V 8.4V Pcb Board Assembly 18650 Polymer Battery

Description:

Standard version: Suitable for starting drills with currents up to 25A below 50W, or resistive loads below 168W.
Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function.

Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions) Product

Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balanced)

Charging voltage: 8.4V - 9.0V

Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use)

Continuous charge current (upper limit): 10A

1. The successful start of power drill requires two 10C-20C power batteries, or four 5C-10C power batteries.(recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6);0V and 8.4V cable, use 2 square mm Above copper wire (cannot use nickel plate!!!)
2. Note 2: When welding the battery for the first time, it needs to be charged before output; wiring strictly according to the figure
   0V, 4.2V. 8.4V, do not touch any components on the board when welding the wire, and do not intentionally short-circuit.
3. When welding the battery for the first time or charging, as long as a single battery exceeds 4.2V, the "430" resistance will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" resistor is seriously hot (you can't touch it when it is too hot), please check whether it is connected to the wrong wire.if the "430" resistance is also heating in the state of not charging, please check whether the wrong line is connected.
4. Do not mix good batteries and bad batteries together! The capacity/internal resistance of 2 batteries should be as close as possible! (1 good battery + 1 bad battery = 2 battery use effect).
