100 amp charging source vs 2 grp31 AGM
My friend plans on running an obscene stereo in his new box on wheels acquisition. He wanted a dedicated power source for it able to power it for a respectable amount of time from battery power alo...

If the AGMs couldn't accept 100 amps at ~50% SOC, then amps would have begun tapering immediately. Instead 94 amps was held for ~45 minutes before tapering began.
Odyssey recommends a minimum 40% rate when deeply cycled. The northstar AGMs are close enough in design that a 50% rate is fine too. These higher Dollar AGMs like Lifeline, Odyssey and Northstar can take Huge currents, and I think they absolutely should be fed these huge currents when depleted.
The lesser$$AGMs which claim a 0.3c maximum should also likely have this rate approached. I don;t think the low and slow recharge regimen is ideal for AGM's, and certainly not for these higher $$ AGM's.
It also seems AGMs suffer more from chronic undercharging than Flooded, so this adjustable voltage PowerMax seemed the best option for not only a high recharge rate, but one which can hold Absorption voltage for long enough to complete the task.
I think 2 12v flooded 31's could also easily accept 100 amps at 50% SOC. I seen my screwy 31 take 40 amps for 45 minutes before amps began to taper. I've seen it take 75 alternator amps when depleted. Depleted batteries not being able to accept large currents doesn't cut it in my book and does not correspond with my observations.
