4S 30A High Current Li-ion Battery Lithium 18650 Charger Protection Board Module 14.4V 14.8V 16.8V Short Circuit Overload

Description:1. The module name: 4 lithium battery chain 2. The modular nature: polymer lithium battery protection board 3.Voltage overload detection: 4.25 ± 0.025V 4. Output voltage overload: 4.15 ± 0.05V 5. A discharge detection voltage: 2.50 ± 0.08V 6. More discharge voltage connection: 3 ± 0.1V 7. Against Overcurrent: 20-30A 8. Working current: 15A (natural cooling: 10A, plus heat sink: 15A, maximum instantaneous current: 30A) 9. Termination conditions: the release protection state then the automatic recovery, without activation (optional charger to activate)10. Main functions: overload protection function, overdischarge protection, short circuit protection, overcurrent protection. 11. operating temperature: -40 ~ + 85 degrees (high temperature environment and please strengthen radiating) 12. connection: welding output 13. module size: 50mm * 22mm * 4mm Applications:The protection commission can be used as the nominal voltage of 14.4V, 14.8V, 16.8V four series of polymer lithium battery group, four sets of 18650 lithium batteries as overcharge and the excessive discharge, short circuit protection. without the activation function in the power demand instantaneous high current, and in the drive request to avoid false trigger protection. So he will use more convenient. Note: No part design on the back, can be attached to the heat sink to ensure a high current work situation for a long time.
