hi, I am looking out for reliable LFP batteries for home power backup.
looking to add batteries in a modular fashion , meaning expand capacity from time to time. Currently using  12v 1100Ah Lead acid, but willing to start with lower Ah  capacity with LFP packs.  My invertor has separate modes for leads acid and lithium batteries.  please share options and price quote. Thank you anticipating your reply.
