I’m looking for a cost effective LiFePO4 solution for a DIY solar system on my Class A motorhome.

Does anyone have first hand experience with these IMPROVE batteries? There’s a guy selling them locally (Ontario, Canada) for $600 but I can get them directly from the manufacturer on Alibaba for half that price (not including shipping which could hurt that). I’m just curious if anyone can comment on the quality.

I plan to build a 400-800w roof mounted solar array and would like to run two of these batteries in parallel for 200ah storage.

Any insight is appreciated

Thanks!

Chuck

No I actually found 2x 200ah KS2 LiFePo4 batteries for a great price so I went that direction

Can you share more details

I bought them used. They were beta test units that were virtually brand new.

They have pretty elaborate BMS which took some tweaking of the setting to get it to play nice with my Victron system but it seems like we've got the settings dialled in now and its working great.
