Hi All,
We took delivery of our new 21C in December. We have the Zap pack with 4 Hublion 100ah batteries.
While I understand that in cold climates it's best to store the batteries inside during the winter, I was a bit intimidated by removing them until I learned more about the electrical systems, so I kept the trailer plugged into shore power during colder weather, since I thought the batteries were equipped with an internal heater and BMS that would protect them in colder weather.
The batteries won't take a charge and I suspect the BMS was triggered and I'm hoping the batteries aren't cooked. Lesson learned - I will move them inside next winter.
I've disconnected them from the system and confirmed 0 / near 0 voltage with a multi-meter. Some online research suggested that it might be possible to reset the BMS by charging them with a standalone charger. Yesterday I connected one of the batteries using a Noco Genius 1 charger. Since it didn't recognize the battery, I used the option to force charge for ~7 minutes. This also failed to wake up the batteries.
I can't find a manual for the Hublion batteries. They don't seem to have any external button to reset the BMS. Anyone have any ideas on what else I should try?
