Hi @10tribu I'll prepare some pictures and write detailed instructions for you. Give me a couple of days to finish it.
Hello jn7, have you do that instruction ?
Hi @10tribu I sent it a couple of days ago thru reverb.com, let me know if you got that. It should be simple, but as noted you’ll need a soldering iron, solder and krazy glue.
i know this is old but i wish the kits were more popular
wow, this is an old topic 
, I wish I was on this forum 4years ago.
all you have to do is to add one of those bluetooth recievers/transmitters to the po. because the already have everything you need built in, usb interface, pass true chergeing, lipo battery management system, and as a bonus, bluetooth. so when you use it, it uses power from the built in battery, and when you plug it in, it charges battery and gives power to po. (same way phone work)
those things are small, so you can built them into the po’s battery compartment.
