Introduction
The protection board adopts mature protection circuit, special IC, imported high current ultra-low internal resistance MOS
( the internal resistance of a single MOS is as low as 3 milliohm), and has perfect and stable charging and discharging protection functions.
The protection board is power type high current lithium battery protection board, which is suitable for equipment with high current,
such as electric tools, motors, electric drills and other equipment.

Attentions:
- The B-, C- wires should be connected with thick wires, and ensure that the pad and the positive and negative poles of the corresponding equipment are correctly welded.
- A single battery needs to be connected in parallel to the required number of batteries, and then the batteries can be used in series.
- When connecting three groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If not, please fill each group of batteries separately
and use them in series. During the discharge test, the battery with the fastest voltage.
