PRODUCT DESCRIPTION
The 4 Series 14.8V 18650 Lithium Battery Equalization Board is tailored for lithium battery packs lacking equalization charging, necessitating the balancing of each battery’s charge. It ensures simultaneous full charging of all batteries in the pack.
This novel 4-string lithium battery protection board is compatible with lithium battery packs with nominal voltages of 14.4V, 14.8V, or 16.8V. It features automatic activation and protection mechanisms that reset once the protection condition ceases, eliminating the need for charger activation and enhancing convenience.
The board offers customization options to meet specific voltage, current, and other parameter needs.
Features:
- The module name: 4 string lithium battery protection board.
- The modular nature: polymer lithium battery protection board.
- Overcharge release voltage: 4.15 ± 0.05V.
- Over-discharge termination voltage: 3 ± 0.1V.
- Working current: 15A (natural cooling:10A, plus the heat sink:15A, the maximum instantaneous current:30A)
- Termination conditions: the release of protection condition then automatic recovery, without activation (optional charger to activate).
