In series connection, the positive tab of one section is connected with the negative tab of the other section (generally, there are wire connections, conductive sheet connections, direct welding of tabs, etc.), and then use the remaining independent negative tabs and positive tabs of the two batteries The ears are negative and positive of these 2 strings of battery packs. Pay attention to the insulation between the independent positive and negative ears! After the series is connected, the voltage is added (7.4V), and the capacity remains unchanged (the cell was originally a 750mAh battery, and now it is still 750mAh).
The charging wiring is to connect the positive pole of the power output to the positive pole of the battery pack, and the negative pole of the power output to the negative pole of the battery pack.
Ref PCM(protection board) of battery, it contains IC chip and Mosfet to achieve safety requirement. It works for overcharge protection, over-discharge protection, over current protection, short circuit protection, interior resistance, current consumption, 0V charge, short-circuit release protection, even sleep function.
Ref wire & connector output info, we generally come with JST, Molex, PH pre-equipped connector. They shall be paired with the customer mainboard female connector. Of course, we also deliver bare wires to the assembly factory for soldering. Most are UL3302, UL1571 AWG wires.
In one word, we produce what you need.
In order to prevent the battery from possibly occurs leaks, overheating, swollen, please note the preventive measure.
