If you mean, hook up another dump load controller and battery to the dump load of this controller, and tap off that--yes you can. He's mentioned this before on his site and this site.
Actually, I do something similar but without the extra dump load controller. Just tap off this battery to charge another set of batteries, this time charging the Maha c401fs which has individual aa and aaa cell charging. It works really well and is alot simpler than using the dump excess. If you were actually charging another, separate battery with different capacity than the first, then the dump load controller on the excess of another is the way forward. If it's the same type of battery and capacity, obviously you can charge them in parallel. The reason I can tap off the battery is that the maha charger is just an appliance connected to the battery as opposed to another battery connected to it--if you catch my drift.[ Parent ]
