Hello. I have been off-gridding for years. I’ve been using AGMs, but my current 2pc bank is slowly dying and 250ah nameplate is really only producing about 60-80 ah. I’m considering going with 4x 180 prismatic, since (pre-covid) I travel to up to 5 different locations per year, and weight and space are issues. I am a sculptor/jeweler and I run a workshop full of tools, off a 2000w Inverter@12v. I would like to have 120ah per night and ideally double for bad weather. Eventually, I plan to go to 24v system, but I can’t buy the inverter right now. So, questions re lifepo4. If I buy 8 prismatics and configure for 12v, can I later reconfigure for 24v? Will I need a different bms for each configuration? If I buy 4 cells now, can I buy 4 more cells in a year, or would that be as bad as using a new and old agm together? I’ve lost my entire industry to covid, and am struggling financially, so I would prefer to scale up, if possible. One way or another, I need new batteries very soon. Thanks folks, and if there is a good source for prismatics near Houston, Tx, please let me know. #toddthecarver
