Need a massive battery for your project? This lithium-ion pack is made of 3 balanced 2200mAh cells for a total of 6600mA capacity! The cells are connected in parallel and spot-welded to a protection circuit that provides over-voltage, under-voltage, and over-current protection.
[pdf] A lithium-ion battery has a nominal voltage of 3.7 volts per cell. When connected in series, the total voltage increases by 3.7 volts for each cell. This configuration allows for different battery pack designs.
[pdf] This section explains how to repair a lithium battery pack by addressing the most common issues: faulty cells, BMS errors, swelling, and short circuits. You will also learn when to attempt repairs yourself and when to consult a professional.
