One of the big downsides of the Tascam HD-P2 audio field recorder ist that it runs on 8 AA batteries. They don’t even last a day and it’s not very fast to change them all out in the middle of a production day.
So I decided to make an adapter to connect my 3S 3000mAh LiPos to it. I simply cut up the cord of its AC wall adapter and soldered two XT60 connectors to the open ends. This way, the AC adapter can still be used, but the new short adapter cord is perfect to connect to the LiPos. To be able to detect low voltage in the LiPo cells I simply hooked up a small LiPo alarm to its balance plug.
This setup proved to be very useful and the 3000mAh battery lasts at least one and a half days!
