The problem with most RC chargers is they have peak detection, which you don't want since these packs might false peak and they usually have some sort of safety timer, which might be turned off.
Important issue there, the wall charger is rated for 0.3A @ something volts but it's not constant(like 0.3A @ 7v, anything bellow is capped at 0.3A and anything above will diminish until the charger can't supply more amps), a proper charger will supply constant 0.3A which is what you want(my old SCE peak at more than 10v so a wall charger wouldn't charge those correctly). Usually the false peaks happen in the first 10-15 minutes of charging, my charger features a delta peak lock and it's been set up at 10 minutes most of my recondition attempts.
My charger arrived, it's currently charging a couple of 1700SC and GP3000 @ 0.5C(half nominal capacity), everything fine.
