PRODUCT DESCRIPTION
The 4 Series 14.8V 18650 Lithium Battery Equalization Board is designed for lithium battery packs that do not have equalization charging and need to balance the charge of each battery. It ensures that all the batteries in the pack are fully charged at the same time.
This new 4 string lithium battery protection board works with lithium battery packs that have a nominal voltage of 14.4V, 14.8V, or 16.8V. It has automatic activation and protection features that reset automatically after the protection condition is resolved. It does not require a charger activation, making it more convenient to use.
The protection board can be customized according to your voltage, current, and other parameter requirements.
