LiitoKala 4-channel Lithium Iron Phosphate Same-port Protection Board with Balanced Temperature Control Bluetooth BMS Support(4S-12V 100A)

1. Rated charging voltage: 14.6V
2. Charging current: 50A
3. Overcurrent protection: 75A
4. Discharge current: 100A
5. Employs a simpler wiring design with a single connector for charging and discharging. Comes with built-in screws for securing terminals, a dedicated high-specification data acquisition cable, and a temperature probe; ready to install immediately.
6. Designed for 4S 12V battery packs, supporting up to 100A continuous discharge current and 60A charging current, easily handling the startup and operation requirements of high-power loads.
7. Built-in Bluetooth module; scan the onboard QR code to download a dedicated app for real-time reading of voltage, current, remaining capacity, and cell status, enabling digital battery management.
8. Provides overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, over-temperature protection, and reverse connection protection.
9. Onboard expansion slots include: UART serial communication interface (for easy connection to computers or smart screens), NTC... Temperature sensor interface (accurately captures changes in battery cell temperature), voltage acquisition cable interface, and KEY low-voltage soft switch interface (no need for high-voltage, high-current switch; output can be turned off by disconnecting the soft switch, safe and convenient).
