Doing a load test on my battery bank 4 Rolls S-555 series/parrell for 12 volts, constant 60 amp draw. The voltage will swing between 11.9 and 12.3 volts, keeps cycling. Any thoughts on this? Thanks

Hi All
I see some views, but no comments. FYI here is the answer I got from Rolls.
"While under discharge, the voltage will ebb and flow; this is normal, and only a four-tenth of a volt fluctuation is well within what I would expect."

That makes sense to me, straight up voltage readings are really only considered accurate when there's no load anyway, presumably for this reason. Nice to have a manufacturer get directly back to you, +1 for Rolls.
