## Questions & Answers

**Q: Why do you need this and a bms? the bms is supposed to balance as well?**
A: Most BMS will only balance while the batteries are charging. The active balancer works all the time. It takes current from a battery with high voltage and sends it to a battery with lower voltage.

**Q: can the 20s also be used for a 14s and 16s battery and Lifepo4 and LI**
A: I cannot say for sure-- but I wouldn't think so.  The unit comes with the number of leads to match the cells and I don't believe it would function correctly without the same number of battery cells connected.

**Q: Will this balancer work without a BMS?**
A: Yes it will. You can actively monitor the state of your battery via blue tooth app and it works quite efficiently. Good for older out of balance battery packs.

**Q: Why does daly balancer show diferent voltage on the app from my original bms? Some times in 30 mV diference**
A: Probably the accuracy of the voltage reading.  These are not "industrial grade" instruments. they are consumer level.  
A 30mV difference is not too big and nothing to be concerned over.
