I finally got an LFP battery ( pylontech 100Ah ). I was using a lead acid bank (LOTS of small SLAs and a pair of GEL) heavily degraded ( around 480 Ah total from which I was able to pull 90~110 Ah ).
I would like to purchase more pylontechs but I don't think that will be possible for a year or two . Meanwhile, I would really like to attach the old lead bank to my system to take advantage of some extra Amp hours.
I've read a lot of threads about people that parallel their LFP with LA successfully and another bunch of people that say that's not a good idea. I'm really puzzled and I feel this like gambling.
LFP is EXTREMELY expensive here, meanwhile my Lead acid bank was almost free (mostly decommissioned UPS batteries). If paralleling is not a safe bet I'd rather keep from doing it.
I have a few fortek "100A" solid state DC-DC relays (which many say they're cheap garbage) which I could use to enable/disable banks so that they won't coexist while charging and discharging....
Does that make sense ?
What would you do in my place?
My ultimate goal is to have three pylontechs paralleled (300Ah LFP) at some point in the future. When that happens I would probably discard lead acid.
Thanks in advance!
