I have two group 24 and one group 31 battery from power queen. One of the group 24 batteries was pretty much toast right out of the box. The BMS would only allow 3-4 volts to the terminal when you weren’t pulling a load from the battery. I figured I would put it back on my lifepo4 charger and see if that might resolve the problem. Long story short the battery charged up to 100% SOC then the charger would click on and off over and over. The Bluetooth feature stopped working and the terminals wouldn’t show over 7 volts when pulling a load or no load. Needless to say to say my group 31 is starting to act strange. I’ve had it for about a week with 2 cycles on the battery and it will not turn off when using the app. You slide the “turn off” slider and you get a never ending spinning circle. Power queen really needs to address these BMS issues, I’m now looking into another brand of lifepo4 battery.
I enjoyed that, but... Since it's "deep cycle" I was hoping it could be taken closer to 0 and not have it's life shortened. So why call it some whiz bang term if it's not. It's just about the same on that front as the rest. Zon published claims says 15,000 charges if never taken below 60%. They forgot the comma in their 15000, yes every detail matters or people lose confidence right up front. Then the app's not up to snuff. Thanks for the look-see. Good video for sure. I've bought 2 100ah Eco-worthy in two years, both fine. I'm in west Texas so no cold issues. If I were in Michigan I'd put them in my heated space with me now that I learned the 32 degree issue. Thanks loads.
Thanks for sharing the technical details of what happened
Very informative! Thanks for sharing this with us 👍
Great info as always

Fantastic video! I sent an email about something we think you’d love. Can’t wait for your reply!
It might be something a firmware update could solve.
