4 Series 30A 18650 Lithium Battery Protection Board 14.8V 16V with Cable

A balance board for drill motor lithium-ion batteries module with an integrated 10-low load resistance MOS tube and an auto recovery feature are included in the 4 Series 30A 18650 Lithium Battery Protection Board 14.8V 16V with Cable.

It offers a balanced current, continuous discharge of 30A for low-power inverters, LED lights, electric drills, and sprayers. (If there is poor cooling, please lower the load current used.)

The scope includes 3.6V and 3.7V nominal voltage lithium batteries, which include polymer lithium batteries like 18650 and 26650, and a charging voltage range of 16.8V to 18.1V With a continuous charging current of (maximum limit): 20A, the board functions flawlessly. The balanced version can start with current less than 80A and power less than 135W (with balance) than the drill.

The board is roughly 46 x 60 x 3.4 mm in size, and it can be mounted on the battery bundle directly or in a small space.

Note:

• Three 15C–20C power batteries or six 10C–15C power batteries are needed for the drill to start successfully (a standard 18650 won’t work!).
• Adhering strictly to the map wiring of 0V, 4.2V, 8.4V, 12.6V, and 16.8V, avoid purposeful short circuits.
• To stop the brush motor from producing a reverse spike when it is under load, attempt to connect a non-polar capacitor (10uF–100uF, capacity, tolerate voltage above 25V) to the positive and negative terminals of the motor. Crack the MOS tube.
• Four battery groups in series: please make sure that the voltage of each group is the same; if not, fill each battery individually before using the groups in series. The discharge test indicates a poor battery group if the voltage drops more quickly.

Features:

• Short circuit protection, overcharge protection, and over-discharge protection.
• Band balancing and overcurrent protection function.
