Active Balance 60A-200A 24V-72V Battery Management System BMS for Lifepo4 and Lead Acid Batteries
QNBBM Balancers equalize voltage for every series of batteries, preventing all cells from overcharge, insufficient charge, or over discharge. This maximizes battery performance and extends battery life.
The balancers are compatible with all LiFePO4 batteries, lithium ion batteries, LTO batteries, and 2V/6V/12V Gel/Flooded/AGM lead acid batteries. Applications include Powerwall, Car audio, ESS, UPS, Solar Energy, Electric Vehicles, and Solar and wind energy systems.

Yes, absolutely. If you use the BMS and balancer together, that will be perfect. Most BMS are intelligent and can display battery information, but you might find the balance performance unsatisfactory. Adding the balancer will help solve this problem.
The power consumption is very low, only 50mW.
Normally if you don't use the batteries for 2-3 months, you need to recharge them for maintenance. Since the balancer power consumption is low, it won't consume much power. Whether you need to disconnect them depends on your battery pack capacity. Contact us with your specific situation for professional advice.
Yes, that is possible. We have solutions, such as using one balancer for two of your cells. We have many customers with special batteries where the balancers work great.
