If anybody makes a wall wart well suited for trickle charging a 1700 Mah NiCd/NiMH pack, I sure haven't seen it. Wall warts generally can't provide enough current to charge that large of a pack sufficiently. You need 170 Mah or so for the charge rate, and most wall warts typically charge at 50 or 75 Mah.
Hmm....
I regularly charge my plane's packs up to 4000mAh 6V on a lowly 4.8v 50mA to 100mAh stock JR chargers.
I may leave the charger on the plane for a few days or so, but my Accucycle shows that the battery does put out faily good capacity.
1700mAh packs?
At least half of my planes have 2000mAh packs or greater and all charge just fine with the "trickle" charge rate of the wall wart.
I don't have to worry about leaving the charger on too long too.
( For safety I also use an extended range meter with load at the field... ).
BTW: Most wall warts put out a higher voltage than the targetted pack...
