I'm a nitro guy & have three gallons of experience. I use spectrum DX7 TX & the AR7000 RX. The stock batt. doesn't seem to yield much flying time (4.8v 1100mAhr NiCd). As of now I don't have a batt. meter (yet) & I've been relying on a Gem 2000 that a good friend gave me. I ordered a Hobbico HydriMax 4-Cell 4.8V 3600mAh NiMH Flat Rx. it should be here next week.

I wonder if my stock a/c wall charger work with this pack ?
I've been look'n at the Sentry LiPo/NiMH Battery Capacity Gauge.

Thank you for your help !

The stock charger is a 150 mah charger for the RX battery, if I remember correctly.

It will take many moons to charge a 3600 mah pack using that charger, could be as long as 24-30 hours.

You should look around for something that will at least charge at a minimum of 360 ma. Find a NiMh suitable, programmable charger...Triton, Triton II, Triton Jr, AccuCycle Elite...others.

And throw the blinking lights in the trash and buy a loaded meter.

NiMh and LiPo batteries will both go up in flames if not charged properly. They are less forgiving than NiCds. As the members above have suggested, you really want to get a programable NiMh charger. The Triton is one and there are many others. To prepare for the future you might want to get one that charges other battery types too. A nice feature of these chargers is the digital meter that will tell you how much you put back in. This can give you a good idea of how long you can fly and what the amount of drain is.
