[RE-wrenches] Is it OK to add EG4LL-S alongside Fortress e-Vault Classic?

[Zeke Yewdall]

FWIW, I have some evault classics running in parallel with a hacked
ReLion/Iron Edison battery (it had a BMS failure and the BMS was replaced
with a JKBMS).   I have victron smarthshunts on each battery, connected to
a cerbo, so I can track how all the different batteries are sharing.  So
far, one of the evaults tracks along very well with the ReLion -- the
Evault contributing a tad more current (it's a 360AH vs the 300A ReLion).
The other evault has something wrong (haven't gotten out to the site yet
with the fortress tool to talk to its BMS, but it's acting like a bad cell
perhaps -- only showing about half the capacity as the good one).  But the
good one and the ReLion track very well with each other every day.  It's
all open loop with some SolArk 12k inverters.  It gets up to 55.6 every day
for a few minutes, then floats at 54.3 or so for the rest of the day.  Been
operating like this for two months or so now.   So.... while I'm sure that
it's not recommended practice, it does seem to work to parallel two
different 16 cell batteries...
