Description
- Overcharge Protection: Features overcharge protection to safeguard your batteries from damage during charging.
- Compact Design: At just 48*20*3.5mm, this BMS is a compact solution for your battery management needs.
- Equalizer Functionality: Incorporates an equalizer to maintain consistent voltage across your battery packs.
- High Continuous Discharge Current: Maximum 20A continuous discharge current, ideal for power drills under 50W or 168W resistive loads.
- 2as2 1|Series Circuit Battery|Balanced Version BMS: Equipped with a balanced version BMS for optimal performance and longevity in your 2S 20A 7.4V 8.4V 18650 Lithium Battery Packs.
Specification:
- Product name: 2 series 8.4V 20A lithium battery protection board (balanced version)
- Charging voltage: DC 8.4~9V
- Continuous discharge current: Maximum 20A (If the heat dissipation environment is not good, please reduce the load current to use)
- Continuous charging current: 10A max
- Product size: 48*20*3.5mm
- 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 battery), with starting current 25A, power drill below 50w, or 168w resistive load
Note:
- To start the electric drill successfully, you need 2 10C-20c d power batteries, or 4 5C-10c power batteries (recommended power battery models: Sony vtc4, vtc4A, vtc5, vtc6) ov and 8.4v connection lines, using more than 2 square millimeters Copper wires (nickel sheets cannot be used).
- When welding the battery for the first time, it needs to be charged before output. Connect ov, 4.2V, 8.4V strictly according to the figure. Do not touch any components on the board when welding the wire, and do not intentionally short-circuit.
- 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 (you can't touch it when it is too hot), please check whether it is connected to the wrong wire.
Package Includes:
1 x 2S 7.4V 8.4V 18650 Lithium Battery BMS Protection Board 20A - Balanced
