What do you think about this battery? It seems to have connectors for both Futaba and Spektrum.

in my case I want to use it for my DX-7.

It should just be "plug & play" shouldn't it. And of course, I can't use the standard charger connection on the radio any more. I have to use the balance contact on the battry instead.

I've used a GE Power RC pack (11.1V 2200mAh - Ebay), it fits like a glove.
I fitted a diode inline with the positive lead which means I can leave the DX7's charge jack alone with no risk of battery damage if the old charger gets plugged for some reason and it drops the max voltage to the system to 11.8V.

I also fitted a charging lead between the diode and the battery. I do drop the battery out of the tx to charge it but I leave it connected.

Works well for me.
