Feature:
Simple and quick assembly: no need to solder, no need to use solder after assembly, can directly output and use the battery
The product can be composed of 4, 8 or 16 batteries in series
In the 4s4p model, there are 16 batteries on both sides of the circuit board, which can reduce the volume, effectively use the area of the circuit board, improve cost performance, and reduce costs
Take 3000mAh for each battery as an example, a complete battery on a 4s1p circuit board is 15V 3Ah, 4s2p is 15V 6Ah, 4s4p is 15V 12Ah, you can stack the number of battery boxes according to your actual needs. The circuit board has the functions of charge and discharge protection, discharge current protection, temperature protection, voltage equalization and balanced charging
There is a 15A fuse on each circuit board, if there is a problem with the battery, it will not affect other batteries
If you choose a charger, you need to choose a DC connector, a 16.8V charger, and it is recommended that the charging current per layer should not exceed 1a
