24V 48V 60V BMS 3S 1A 2A 5A Active Equalizer Balancer for LiFePO4 and LTO Battery Energy Equalization
QNBBM Balancers equalize voltage for every series of batteries, preventing all cells from overcharge, insufficient charge, or over discharge. This technology 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.

Frequently Asked Questions
Q1: I have a BMS already, can I use the balancer?
Yes, absolutely. Using BMS and balancer together provides optimal performance. Most BMS systems are intelligent and display battery information, but balance performance may be unsatisfactory. Adding our balancer solves this problem effectively.
Q2: What is the power consumption of the balancer?
The power consumption is very low, only 50mW per cell.
Q3: If I don't use the batteries for a long time, should I disconnect the balancers?
For batteries unused for 2-3 months, recharging is necessary for maintenance. Since balancer power consumption is minimal, it won't significantly drain the battery. Whether to disconnect depends on your battery pack capacity. Contact us with your specific details for professional advice.
Q4: My battery is NiCD or other special battery with nominal voltage of only 1.2V. Can I use your balancer?
Yes, that is possible. We have solutions, such as using one balancer for two cells. We have many customers with special batteries where our balancers work excellently.
Q5: What are the applications of your balancer?
Lithium batteries, lead acid batteries, and super capacitors.
Q6: What is the delivery time for your balancer?
1-2 business days if in stock. 1-3 weeks for volume orders.
All long pleasant business starts from good communication. We welcome your inquiries and are always available to answer your questions. Even if we can't make a deal, we're happy to share information and learn from each other.
