As soon as I pulled the batteries, it was clear they have the internal heating option, so hopefully rules out one possible cause of failure.
I tried individually charing one of the batteries with a Victron IP65 charger and no luck. It reads about 2.5 volts after charing, but can't get above that, so it seems the BMS is still locked or there's a bigger issue. I also tried the flash charge method, which didn't seem to do the trick either.
Sounds like it's time to contact ETI / Hublion.
Agreed. It's become a moot point for us. We are fortunate enough to have a heated shop where we store the 5.0 and since the batteries are under the dinette, even when we travel in very cold weather, we will keep some heat going in the coach.I don't follow why a RV would not have heated LiFePO4 batts................?
Granted, my heated batts were factory installed in the front storage box, when they still did that, but still...................
If you measured 2.5V after a charge, I fear your batteries are beyond repair. The BMS should either be ON or OFF, and a fully discharged Lithium battery is about 10V. The 2.5V reading implies either the battery pack is failed, or the BMS only partially activating. Either way, it's time to contact HubLion.As soon as I pulled the batteries, it was clear they have the internal heating option, so hopefully rules out one possible cause of failure.

Wow. Good to know and a pleasant surprise. Thanks for sharing that.Per ETI:
If your Escape came from ETI with HubLion (not Go Power brand, didn't ask about those) batteries (black or green top) , they ARE heated.
Ah - I had the state and town set in my profile, but apparently it was only pulling in the town. Should show the correct location now.Where the heck is Pomfret? When I click on the word, Google maps shows Winnipeg but I’ve lived here all my life and have never heard of it.
Unfortunately I don't know and Hublion support didn't know either. I suspect something with the battery heater not functioning and the BMS still allowing a charge to go through.@vtabv So what was wrong with your batteries and what caused it? I am just wanting to avoid having that happen to me. Glad Hublion is taking care of you.
