SOLD!!!!!1-S QNBBM Single Cell Battery cell Balancer for Lifepo4/LTO (16 total for sale) in S Carolina.

[Shawn Hayes]

I have 16 of the 1-S active balancers for sale. All brand new, never used. Can be used for LiFePo4, LTO and possibly other batteries. You’ll need to be more familiar with these, since I never used them I’ve forgotten a lot of the details on what they can be used with.
I’m asking $15.00 each, plus shipping, if you buy them ALL!!
If you buy less than all 16 I’m asking $18 each, plus shipping.
Please message me with questions.
Thanks.

They claim anywhere from 2-10A of balancing current dependent on source/age. They are useful. I have them on my 14S NMC (3.7V) bank. Their ratings are a bit misleading. They only deliver the claimed rate when the difference between cells is 1V. If 0.1V, they will only deliver 1/10th of the claimed current; however this is still notably higher than any passive BMS, and they work any time the voltage difference is greater than 10mV. With LFP cells, it means they'll mostly only work when you want them to - in the upper and lower legs of the voltage curve.

Worth noting:

"Note: This balancer emits a very high-frequency tone that some people can hear if they are within 10 feet." - this is true. This might be annoying to some if installed in a quiet space.

At $15, if I didn't already have more than what I need, I would scoop them up.

Awesome info!! Thanks for your input!! I bought these thinking I’d use them. However, I think my setup is doing very well and no need to keep them if I’ll never use them! Rather someone else put them to good use!!
I researched and read about them on the forum, hence, I have 16.... lol
