Enerkey BMS 200A 250A 300A 16S-24S Active Balance BMS Balance Current 8A Continuous Current 15A-300A Lifepo4 li-ion LTO Battery
16S-24S 1A-8A 15A-300A Smart active balancer BMS for Lifepo4/Li-ion/LTO/SIB Batteries with CAN/ RS485
The intelligent lithium battery protection equalization board is a protection equalization management system tailored for large-capacity series battery packs.
This lithium battery equalization part uses supercapacitors as the medium to achieve active energy transfer equalization.The voltage acquisition range is 1.5V~4.5V, with an accuracy of 1mV. It is suitable for mainstream ternary lithium, lithium iron phosphate, and lithium titanate batteries on the market.
Supports 16 to 24 strings of batteries and supports disordered power-on.
This lithium battery protection equalizer has Bluetooth communication function and is equipped with mobile phone APP software. The balancer can be connected to Bluetooth to view data such as single cell voltage, single cell maximum voltage, single cell minimum voltage, single cell average voltage, maximum voltage difference, total voltage of battery pack, real-time balancing current, running time, balancing status and device temperature, and the device balancing parameters can be modified online.The smart active balancer bms also has CAN/RS485 communication port, We can as your agreement to customized it.

Precautions:
①. Installing the protection equalization board requires a certain amount of electronic knowledge.
②. Welding the cable: The first cable (black line) is connected to the total negative pole of the battery, the second cable (red line) is connected to the positive pole of the first battery string, and the third cable (red line) is connected to the positive pole of the second battery string... and so on, connect all the cables;
③. Detect the cable: After connecting the cable, measure the voltage between two adjacent cables from the head of the cable to confirm that there is no problem of wrong connection or missing connection in the welding sequence of the cable.
④. Connect the B+ line of the protection board to the total positive pole of the battery, and then connect the sampling cable plug to the protection board. After activating the protection board, confirm that the voltage before the board (battery voltage B+.B-) and the voltage after the board (P+.P-) are consistent.
