I'm sold. These little guys just work. Latest build is a 4S2P 12v LIFEPO4 and the cells have been as much as .20 out of balance while charging. Within a couple hours they are exactly the same. I've read some horror stories with these and the main thing to.prevent problems is to install these before the battery pack is a mess of mismatched voltages.

Balanced like a champ for 10 minutes after I got it installed on a 16S LiFePO4 pack. Would be a great unit, if it didn't let the smoke out and stop functioning.

I found this battery balancer very useful and effective. I used it daily for months, but it died due to my error. Please triple-check the battery pack's resistance. I failed to notice a dead battery with high resistance, and the capacitor exploded and melted my silicone mat. The photo shows the melted area on my mat.

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.

This Active Cell Balancer is great! I had a very unbalanced 12 Volt (3 series) Li-Ion battery pack and it gradually brought all 3 cells to the exact same voltage (within a couple miliVolts of each other). What I really like is that it balances the cells regardless of their voltage or state of charge (unlike the passive resistor cell balancers which only work when the cells reach 4.2 Volts). This is my favorite feature since I only charge my cells to 4.0 Volts (approximately 80% state of charge for long term life). I performed a very careful measurement of the quiescent current and it is less than 10 mA (so no problem for my setup to leave it running continuously). A great product!
