This is interesting because when I brought up the idea of desulfating during discharge and recharge, it was soundly shot down. The claim was that sulfation is the very definition of discharge and that zero benefit from desulfators could be realized until the batteries are 100% full.
I still like the idea, though I have no data to back it either way.
BFL was pretty burnt on testing at the time, but I hope "we" can find a way to explore this idea some more.
And who knows... we have been basing our thoughts on our Vector desulfators. It's certainly possible that Wiz's rig here is superior.
Perhaps we could convince Wiz to remove the desulfator for a couple of weeks and see if he notices any capacity loss.
