1. Module name: 4 string lithium battery protection board
2. Modular nature: polymer lithium battery protection board
3. Overcharge detection voltage: 4.25±0.025V
4. Overcharge release voltage: 4.15±0.05V
5. Discharge detection voltage: 2.50±0.08V
6. Over-discharge termination voltage: 3±0.1V
7. Over-current: 20-30A
8. Operating current 15A (natural cooling: 10A, plus heat sink 15A, maximum instantaneous current 30A)
9 . Termination condition: release the protection condition, then automatically recover, no need to activate (optional charger activation)
10. Main functions: overcharge protection function, over discharge protection, short circuit protection, over current protection.
11. Working temperature: -40~+ 85 degrees (high temperature environment, please strengthen the radiation)
Connection: welding output
13. Module size: 50mm * 22mm * 4mm
Application: The protection board can be used as a four-component polymer lithium battery pack with nominal voltage of 14.4V, 14.8V, 16.8V, and four series of 18650 lithium batteries for overcharge and overdischarge, short circuit protection. There is no high instantaneous current to activate the function in the power supply application, and erroneous trigger protection is avoided in the inverter application, so it is more convenient to use.
Note: There is no part design on the back and can be connected to the heat sink to ensure long-term high current operation.
Package includes: 1PC * 4S 30A 18650 lithium battery protection board
