This is the 8V variant of the 4S High Current up to 30A Lithium Battery Protection Board Four Series of 14.8V 16.8V in Battery Protection Board. Available at ₹114.46 (₹97.00 + GST) with free shipping across India.
PRODUCT DESCRIPTION
The 4-Series 14.8V 18650 Lithium Battery Equalization Board is designed for lithium battery packs that lack equalization charging, ensuring that each battery in the pack is balanced for optimal performance. It enables all batteries in the pack to charge fully and simultaneously.
This advanced 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 protective condition is no longer present, eliminating the need for manual charger activation and improving overall convenience.
The board can also be customized to meet specific voltage, current, and other parameter requirements, providing flexibility for various applications.
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).
- Main functions: the overcharge protection function, over-discharge protection, short-circuit protection, over current protection.
- Working temperature: -40~ 85 degrees (high-temperature environment and please strengthen radiating).
- Connection: welding output.
