The battery comes with a male JST type connector but I decided to go the more permanent way and just solder the wires directly to the switch I've already got wired up in my MTR.
Here's the battery compared to the 9v its replacing:
|The DC-4S is the charger for the LiPo, also very small!|
Anyway, I ground down the one corner of the top case on the MTR (not pictured) and passed the wires into the MTR that way. Unfortunately with these batteries, there's also a balanced lead that you plug into the charger to control the cell balancing. In my case, the charger I got actually charges through the balance wires so it works out OK, I don't have to remove the battery from the MTR in order to charge it!
I am getting 5w on 20m and 4.5w on 40m with the battery at 11.7v, which is about what I would expect since that was roughly what I got with my 8 cell NiMH pack which tops out at about 11.2v. I made a few QSOs on 20m and went outside for a glamour shot. That yellow really looks nice next to the blue!
