LifePo4 Voltage at .5C - .6C Discharge
Our two GC2's (with 100% charge) drop below 12v while under a 100a - 125a load. When they reach 50% (at 100a - 125a), voltage drops into the low 11's while under-load. What kind of under-load volt...

What kind of under-load voltage can I expect with two 100ah LifePo4's (paralleled) with a 100a - 125a load? At 100% charge? At 10-20% charge?
To some degree it kinda depends on the nature of the load your battery is subject to - not all loads of the same amperage react in the same way - inductive loads are the most severe...
Having said that, given the LFP scenario of which you describe you should have no problem... With only one Aims 100a/hr LFP, I’ve seen about a 95 dc amp air conditioner load (Coleman Mach 1 p.s.) down to an amazingly uber low 6% SOC - but for the record this was inadvertent, not done purposely and with concurrent solar...
Along with a faster harvest recovery, this is another attribute of LFP’s...FWIW, my former set-up was with two GC’s in series, and now with just one 200a/h Aims LFP..
