Default xmitter battery

What LIPO battery would be best for a Futaba 7C transmitter? Thanks Dean

Since your TX was designed for 8 nicad batteries which we call 9.6 v, the ONLY modern battery I would use is a 9.9v LiFe battery and the proper charger. Do not charge it with the old charger.

Using a lipo in a TX not designed for one, cost me my best TX, even though many many people said they had done it. And to be fair, mine worked until the Vreg went out and fried the entire board

As Wildflyer .... only consider LiFe battery if determined to change...

Just out of interest - why change from NiMH ?

I know its old hand ... but TBH - in some ways I prefer NiMH .... radios designed to have charger plugged in without need to monitor balance etc. No need to storage charge ...

If using individual cells - easily obtained new ones in local supermarket.
Easy to make your own pack using common holder and tape.

But I do have LiPo in some of my radios (9X .. 9XR) because they can be set to use them ... but those LiPo's are ex flight ones that no longer give good flight performance. But good enough with the low discharge demand rate of Tx.
