Battery about to pop?

Right since installation in Nov 2022, I've had trouble with battery capacity and odd cell voltages. GivEnergy put this down to the firmware issues at the time and asked me to bear with it. I throttled-back the charge rate (my own intuition) and waited it out on Beta firmware.

I realised a few weeks back that the Release firmware is now available. (Bit irritated that Giv never told me...) I got that installed and removed the charge rate throttles. And now, every night, I get the cell voltage spikes shown above. I also get Overvolt warnings consistently every night during the same timed charge.

GivEnergy have said they'll put me on the list for an engineer visit, but they're not exactly super responsive. I've messaged asking whether this is just damaging the battery further, while I'm waiting to have an engineer visit arranged, but they've gone quiet.

So, genuine question - is it going to actually pop?

Cheers

Are you on battery firmware version 3013?

If so, I think there’s others who have mentioned this issue elsewhere on the forum.

The fact you get an alert has to be a good thing. The system knows and hopefully can take action to prevent damage to the battery!

If the alerts didn’t exist I’d be more worried.

It’s not ideal I guess, but fingers crossed, it’s ok.

Riscy had the same issue, GE downgraded me to 3012 and since then it's been pretty good. From what I was reading 3.65 is the safe upper limit and 3.7 is the fail safe cut off of sorts. While I don't think it's good for the health, I don't think you have to worry about safety. (Not a battery chemist so take with grain of salt)

Thanks both. Somewhat reassured... 😉

Yes, on 3013.

I had similar issues with the same messages, then eventually the battery stopped working. Giv engineer replaced the BMS and all been fine since. Apparently the BMS also learns each time you get a voltage spike, so it may just settle down. But if in doubt then go back to your installer
