Battery Choice Opinion Please UPDATE
Updated 26 April ---------- Thinking of getting one of these to replace an old pair of wet 6s, where the price here is similar to new 6s. Not sure if it is suitable for RV use doing 50-90s some...

Sorry, I missed that above post from Mex before I started things. Too late?
Got it installed and on Trimetric, no charging, parasitic loads under an amp. Voltage 13.0 (Tri only does one decimal point)
Turned on converter set at 13.8, amps went to plus 8ish then tapered fairly quickly down to 0.4ish and below. Decided that meant battery was full. ??
Turned off converter, turned on 31.5 amps worth of lights and fans. Voltage dropped to 12.1 and held there for 15 minutes, then went up to 12.2 and held there for another 15 minutes and beyond-still there. I will leave that on for some more time, observe bounce- back voltage, then recharge back to full at 14.4ish spec (plus a bit for 52F temp) and let amps fall to near zip, then drop it to 13.8 float.
So far I think things look fairly decent ??, but I would like to do a full 10 hour run at the 20 hr rate (12.5a) to 50% SOC to get some actual capacity notion. Can't do that today.
