HW-391 2S 20A 7.4V 8.4V Li-ion Lithium Battery Charger Protection Board 18650 BMS Board Module Balance
Specification:
Charging voltage: DC8.4-9V
Continuous discharge current: Maximum 20A (if the heat dissipation is not good, please reduce the load current to use)
Continuous charging current: Maximum 10A
Applicable options: Suitable for lithium batteries with a nominal voltage of 3.7V and a full charge of 4.2V (including 18650, 26650, polymer lithium batteries), with a starting current of 25A, power drills below 50W, or 168W resistive load.
Product size: 48*20*3mm
Product weight: 5g
Packing size: 50*50*15mm
Package weight: 5g
Precautions:
1. To successfully start the electric drill, you need 2 10C-20CD power batteries, or 4 51-10C power batteries (recommended power battery models: for sony vtc4A, vtc5, vtc6) OV and 8.4V connection lines, use more than 2 square millimeters Copper wire (nickel sheets cannot be used).
2. When welding the battery for the first time, it needs to be charged before output. Accord connects OV, 4.2V, 8.4V according to the figure.
3. When the battery is being welded for the first time or is being charged, as long as a 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 very hot, please check whether it is connected to the wrong wire.
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2mm measuring deviation due to manual measurement.
