8S 24V 120A
Features: 1. Adopt high-quality (A-level) protection integrated circuit IC of Japanese Seiko solutions. 2. Resistance power Mosfet. The radiator will greatly help cooling. 3. The IC itself has a power balance function. The circuit is simple and reliable. 4. The typical voltage detection of each mobile phone. Therefore, any battery charging or over-discharging will be prevented. The overcurrent and short circuit functions are very reliable. Long-term short-circuit of the load will not affect the PCB and battery. Temperature protection during charging and discharging. 5. Very low power consumption. The power consumption of the whole machine is less than 50uA. 6. The PCB adopts high anti-corrosion, high impedance ESD conformal coating. Specifications: Name: Lifepo 8S 24V 80-150A BT Version with Fan BMS Same Port with balance Features: Same Port with Balance Suitable for: scooters, electric vehicles, 18650 lithium battery packs, etc. Colour: Black material: metal The main functions are: overcharge protection, overdischarge protection, overcurrent protection, short circuit protection, temperature protection, etc. #Bluetooth module Specifications: Color: as shown Material: Plastic + Metal Bluetooth module: available connect with Android and IOS App and can review the battery status in real time by mobile phone. Product activation Method: Pls refer to following link to understand bluetooth set up by APP. Package includes:
For our smart bms,when first use,need to activate first,then B- P- can be conductive,voltage from P- can be same from B-, then BMS can work well.
Method ①: there is an activation switch on the board and click the button.
Method ②: Press the button on the bluetooth module to activate the bms directly.
Method ③: Charge activation, B-line must be connected to the total negative pole of the battery pack when
