QNBBM balancers are designed to actively transfer energy from the highest charged cell over to the lowest charged cell. A voltage difference of 1V will draw a current of 3A, a 300mV difference will draw 1A. Using these balancers in a high capacity bank with slight capacity differences helps get more usable capacity out of the bank before the lowest capacity cell nears empty by transferring energy into it from other higher charged cells. LED lights on top indicate whether the balancers are in balance with each other, are charging other modules, or are receiving a charge.
There are two types for sale, 12V and 3V.
Voltage range per type:
12V: 9V-15V
3V: 2V-5V

Found them through internet search. Requested mobile installation. They called back within 2 hours to set up an appointment. Turns out they had a shop near me, which saved me 50% on installation cost. Took about an hour.
Prompt, quick, professional service. So much cheaper than getting another car. I would highly recommend their service to anyone who needs a hybrid battery replacement.

I was so grateful that my friend told me about this company. What I thought was going to be a $8,500.00 repair, as quoted to me by my regular auto shop, turned into a $2,400.00 repair. I will be forever grateful to Greentec EV & Hybrid Batteries. Thank you guys so much. Their customer service was excellent over the phone, and my experience with the technician that came to my home to do the repair was also excellent. I can’t thank you all enough. You really saved me!!

The hybrid battery on my Prius started dying and I managed to drive to the shop so I left it with them and told me they’ll finish it by tomorrow at 11am but they done it a lot earlier and faster than I expected. The car was running great again with the purchased of 12 month warranty remanufactured. I’m highly satisfied with the work they’ve done and I recommended them big time.

I purchased, but was unable to get any information on or instructions for installing them, so unfortunately I put in for a return.. if I need them, it would be nice to have been able to use them (your website shows for my application, they are necessary). So far have had success when buying batteries and customer service overall with GreenTecAuto. Will recommend their batteries for sure.

I am running two strings of 4 of these equalizers with 8 valence batteries….they are doing what they are supposed to do. Initially had a failure out of the box, but Greentec took care of it. Thank you.
