New to this forum, looking for information about LiTime lithium batteries (formerly Amphertime). Has anyone used a Classic 150 with these batteries and how did they work for them. I am looking at the 24v 200amp batteries (400 amp bank of 2 batteries in parallel).
I don't have those batteries but they should work with Classic though you will need to watch the charge parameters until you get them tweaked properly. By tweaking I mean the cables voltage drop offset on the Classic needs to be set properly at the top charging point.
Personally I would consider other batteries in the same price range because of these reasons - better warranty , better bms ( with communications,some smart bms functions, and monitoring software), probably better quality cells ( compare the specs carefully) , and ability to open up case if ever needed ( a metal case and not a glued together plastic one), some models have display screen built in, and the others might have better customer support. Also better connection terminals.

Also consider upgrading to 48v though I understand that might mean an inverter upgrade too.
