Hi Everyone

My Mom has a 3.7kw MD Solar lithium battery installed and we would like to add more battery capacity. My question is the following can we add any other battery ie Pylontech or would we need to stick to another MD solar battery? On a side note there is nothing wrong with the current MD solar battery i just want to know if we have the option should we find better pricing with another battery manufactorer?? Thanks in advance for the replies. (Her system is a Victron Multiplus 2 5kw, with 12x 405w Canadian solar panels, Venus GX and Victron 250/100 MPPT, Solar MD Smart logger, Venus GX)

No, as far as I know it will have to be another 3.7kW SolarMD battery.

For the average user - no

For the intermediate user - kind of,if you match the cells and chemistry

For the advanced user - yes

Thanks for the responses guys. 

If I am not mistaken the Solar MD is an 16 cell battery and the Pylontech is 15 Cell. Really do not recommended to mix these two. Rather stay with the Solar MD batteries.
