Two Way Radio Battery Pack

I want to put 4 AA NiCad or NimH batteries in a holder (Radio Shack 270-383) and connect two set of positive and negative leads. One to a DC Power Jack (Radio Shack 274-1565) for when the battery pack needs to be recharged and the other to a DC Power Plug (Radio Shack 274-1567) for when I want to use their power. Will this work?

An AA battery (pronounced either "ay-ay" or "double A") is a dry cell-type battery commonly used in portable electronic devices. Electrical output of alkaline batteries in this size is 1.5 volts, 1800 to 2600 mA·h, while rechargeable batteries commonly output variably 1.25 V. The output of an AA battery is the same as that of an AAA battery, but AA batteries provide power for a longer period (hence their larger size). An AA cell measures 50 mm long, 14.2 mm in diameter, and weighs approximately 23 g (1.97 x 0.56 inches and 0.81 ounces).

The capacity of rechargeable AA batteries varies with the technology used. Nickel-cadmium (NiCad) AAs with a capacity of 650 to 800 mA·h are commonly available, while 800 to 1000 mA·h are rarer and more expensive. Nickel metal hydride (NiMH) AAs are available in various capacities ranging from 1400 to 2700 mA·h.

NiCad AAs are commonly used by people powering model cars or other (relatively) high-current-draw devices, where the older NiCad technology performs better than NiMH. NiMH AA's designed for high current applications are beginning to become available; these use different construction and have lower capacity (1400-1600 mA·h) than the highest capacity NiMH cells.

hold a wire in one hand and a battery in the other then stick the wire into an electrical socket. that should work let me know!

Pardon me if I sound skeptical about your license, but how did you pass you license exam if you can't estimate the range of this radio?

I have two 12 v dc motors run off a car battery, continually charged by a car 50 amp alternator run by the 6.5 h.p. lawnmower engine. One motor driving each rear wheel. I am controlling with a "Futaba" transmitter and reciever through a 12-15 volt 50 amp electronic motor speed controller to the two motors. When I hooked it up for a first trial, it resulted in three problems. I'll list them in order of importance to me but anybody answering any of them will be GREATLY appreciately by me!
1. There is no reverse function
2. When I release the joystick on the transmitter and it springs back to center, the motor should stop right? It doesen't. It doesn't stop untill I push the lever all the way towards the opposite direction from which I want the motor to turn. Kinda like even if there was reverse, I wouldn't have enough joystick movement to reach it.
3. The motor speed controller has a "BEC" 3 v battery eliminator circuit. I still need to hook up my 4 cell battery pack to use it?. HELP!

wow...too cool!

You sound like you're attempting to build a BattleBot LOL!

I'll bet if you hooked up with one of their engineers or designers or found a forum for the battlebots, you'd solve your problem. Some of the links below might have either forums or contact info for some people who already have them.

It would be cool to have a remote controlled Lawn Mower! I'd love to hear about your progress on this :)

For part 3 - "BEC" or Barrety Elimination Circuitry (I think) is a wiring that takes power from the main battery (think of the main battery pack on an RC car) instead of needing a piggy back pack for the ESC, so as I understand it you need the 4 cell pack to run the ESC. If I could get a hands on ans actually see it that would probably help.
