I have two Weize 100 ah Lipo 4 batteries that my 6 120 watts panels charge. I am wanting to add more battery capacity. These 2 batteries are about 6 months old and I have them wired in parallel as I do my panels. I would like to go from a 200-amp system to a 400-amp system. Can I try to find the same batteries and brand that I have now and add them to the other two wiring them all in parallel? I do not know if adding 2 new batteries in parallel to the existing batteries in use will cause a problem since am upgrading to a 3000-watt pure sine wave inverter from the 2000 watt that I am currently using. I am currently using a Renogy 60 am MPPT controller but also have an Epever 60 amp that I am not using at this time. Any comments on what I should do would be appreciated.
This is an edit to this problem. I find that I cannot purchase the Weize 100 ah 12-volt Lipo4 batteries anywhere. It seems they have stopped making them for some unknown reason. Tried to contact the factory with no answer. So I am looking at either getting two 200 ah 12-volt Lipo 4 batteries to get my 300 ah I am wanting or buying two 100 ah batteries of another brand like Chins and mixes them with my current batteries and then hoping for the best. Any comments and suggestions would be appreciated.
