While I have had a 50ah Amped Outgoors 36v for my Force and 2 Ionic 50ah for electronics for a few years in my boat, in my truck camper I still have 4 interstate gc2 6v`s and they weigh a ton
Prices have dropped for lithium materials it seems and there are a lot of funny named Chinese battery's around , I almost bought 2 Litime 100ah 12v`s to replace the ones in the camper, the ones with low temp cut off for charging at 32 degrees .
I didn't want anything with internal heaters like some claim to have ( Will Prowse ) says most of them are not worth it , But I do want bluetooth so I can see the temp of the battery and SOC
I wish Litime had bluetooth , but not yet , it looks like a lot use the same bms with the same functions , some now have bluetooth and by the looks of the app it may be the same one
Kind of seems like a c**p shoot to pick an cheap off brand , but it seems the main reputable brands haven't lowered their prices to reflect the lithium material price drop
So I investigated these as much as I could , haven't found any bad reviews , has low temp charge cut out at 32 but it works differently , cuts the charge amps way down and them off at a lower temp .And has bluetooth
In the camper I plan to use silicon heating pads under them
tied to a thermostatically controlled switch , if I have my solar running .
These seem to cheap to believe , We will see , I bought 2 of them
