Product Features:

The protection board is suitable for 3.6V/3.7V batteries of the 18650 Li-Ion.
Various stable protection functions for charging and discharging, such as B. precise overcharge protection, overdischarge protection, overcurrent protection, and short circuit protection.
The balanced processing of the basic equipment of the batteries, suitable balanced current, appropriate heat development does not affect the performance of the battery block.
It has an aluminum foil that would improve the heat dissipation of the MOS pipe and extend the life of the MOS tube.
Low power consumption while sleeping, can save energy.
