The QINIZX 4S/5S/5A Active Equalizer Balancer is a high-precision energy transfer module designed for Li-ion, LiFePO4, and LTO battery packs between 30-200AH. Featuring a max balancing current of 5.5A and voltage accuracy within 5mV, it actively equalizes cell voltages using a flying capacitor charge transfer method. Its ultra-low quiescent current sleep mode (<0.1mA) and under-voltage protection ensure efficient, safe operation. Built with a 2OZ copper PCB and low-resistance MOSFETs, this compact board (2.71x2.28x0.63 inches) is engineered for durability and optimal battery longevity.

Si me funciona muy bien
Yo el puso en un pila de 12s y 48v si hace su trabajo

Has no info on how the maker intends me to use it,
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.

Worked for 10 minutes, then burned up.
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 wish these had been available 20 years ago!!!!
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. :-)

Balances your Battery Pack Continuously
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!
