Battery Question
 

Hello!
I'd like to use a dual battery setup in my Jetmach 60. The engine I'm running is a JC BEE II KS.
The Turbine Manual says to use a 5cell 6 volt battery for the receiver. What's the best way to plug the Dual batteries into the receiver? (Ar7000) Do I use 2 switches etc??

Could I use a lipos with a regulator the same way?
Thanks

One battery gets plugged into the normal battery port. The second battery can be plugged into any unused channel. If you don't have a spare channel it can be connected to any channel with a Y. Both batteries need to be 5cell and on its own charging switch.

Yes, you can do the same with two Lipos. Each battery would need its own switch and regulator. I'd suggest using nicads or A123's and no regulator.

Bat Share. Don't leave home without it. Best thing to ever happen for a set-up like your wanting to do!!! I have several and love them.

Really would like to go with A123 but they're not recommended them for Kerostart?

That thread is referring to the ECU battery. Use what came with the engine, or a Lipo.
Your initial question was about receiver batteries.

oh ok! didn't realize that. So I could use A123 for the reciever , even though that JC recommends 6 volt?

RE: Battery Question
 

A 2 cell A123 is rated at 6.6 volts and will work fine as a receiver battery without a regulator.

Everybody has their favorite battery set-up and I don't wish to start a battery war here, but I use 5 cell nicads in all my planes and am in no hurry to try A123's. They cost about twice as much and weigh about half as much as nicads. A friend crashed because he was using a battery chemistry he wasn't familiar with. If this is your first jet and you don't already have an A123 capable charger I would recommend sticking with nicads, you'll have enough of a learning curve with everything else. You shouldn't need a lot of battery capacity batteries on a plane like the Jetmach 60.
