Never got to use it. Maybe it is meant for an experienced user, Other than wiring order, has no information. Does it need to be used with a charger, Does the BMS have to be disconnected ? Do the batteries have to be fully charged ? When should it be used ? It is a new type of balancer (Capacitive) I don't have time to spend looking all over the internet only to see people arguing pros and Cons. I am using Daly Smart BMS, but it has a different plug for the balancer. It would be a good idea to use a standard plug, so you could just unplug the wires from the BMS, and Plug them into this device.

These things are amazing. They do a better (more accurate, and faster) job of balancing than my balancing chargers, and can be used for pre-charge, during charge and post charge balancing. I never liked using BMSes on my battery packs, preferring just to monitor conditions closely to get away with using simpler systems, fewer components to break down and the ability to over-power for short periods. I sure wish these had been available 20 years ago when I was actively building a lot of E-bikes and other battery operated systems. They would have made life much easier. Now, if the company would make similar modules that would balance 6 Volt Lead Acid battery arrays, I could vastly improve my solar power system for a reasonable cost. :-)

Works well and easy install

worked great to balance my 200AH RV batteries. Cells where ranging from 3.6 to 3.2 a few hours after installing this they where all the same.

Thank you!
