DALY 4S-16S BMS 15A to 200A Protection Board with Balance Wire and Temperature Sensor for Lithium Battery Pack（LifePO4 16S 48V,100A）

Good Simple BMS and it's tiny for a 29.4v 60A. I've used two of these so far on 7S 70ah Li-ion battery packs for my grandchildren's 24v ATVs. Only needed 30A draw but I like to double that for a BMS to be sure it lives a long life. I also run 5 amp flying capacitor type balancers on battery packs over 10ah. Otherwise it would take a week for the BMS to top balance a 70ah pack.

Seems like a nice unitI installed it on a battery that was flooded during Hurricane HeleneThe old BMS was toasted of courseThe four cells were showing 3.3 volts so I installed the DALY BMS and it is back on service !Hopefully it holds up... Time will tell.

Had to send the first one I bought back, It was reading slightly lower voltage on the output wires than the pack. Once I put load on it, there was no power. For some reason the BMS was shorted /triggered from the factory, I tried turning the bike on multiple times and could not get it to work. I returned it and got another one, This time it was able to come out of it after 3 times turning the switch off and on. I have had other DALY BMS' in the past that did not have this trouble out of the box....

Son de buena calidad porque pedí otra marca que eran más barato y luego tuve que cambiarlos por esta. Que es mejor calidad

Perfect, simple

Installed this in a 12v 200Ah LifePO4 that I bought but had a dead BMS. I got all the cells up to proper voltage and then installed this in about 30 minutes.Works great, good BMS. Comes with a sheet showing and listing installation directions.

Lo instale en una batería de s3 y no me esta dando voltaje, porque?

Positive: a small solid package.Negative: the included NTC temp sensor does not prevent charging below freezing. Leads for cell monitoring too short for my 2P4S setup, no crimp lugs included.This BMS does the absolute basics only, nothing beyond that. No app support. No settings options. No low temp protection.
