QNBBM Balancers equalize voltage for every series of batteries to prevent 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. Ideal applications include Powerwall, Car audio, ESS, UPS, Solar Energy, Electric Vehicles, and Solar and wind energy systems.

Looking for distributors! Make DIY Battery Easier!
Yes, absolutely. Using the BMS and balancer together provides optimal performance. Most BMS systems are intelligent and can display battery information, but balance performance may not be satisfactory. Adding the balancer solves this problem.
The power consumption is very low, only 50mW.
Normally if you don't use 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 to disconnect 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.
Lithium battery, lead acid battery, super capacitor systems.
1-2 business days if in stock. 1-3 weeks for volume orders.
