Title: Replace Battery with external Power
Post by: PittsburghTrainPaPa on March 14, 2024, 04:19:09 PM

I would like to eliminate the rechargeable internal battery on the Tiny TV and wire it to an external 3 to 5v external DC power source. The external wire connection would have an ON/OFF relay .   Does this sound possible?   Reason the TV is to be installed in a model that I will NOT have access to once the TV is installed.

Which TV are you using? TinyTV DIY, TinyTV 2, or TinyTV Mini?

Yes, for the TinyTV DIY Kit you can replace the battery with a switched 3-5V supply connected to the JST SH connector. Note that 5V should absolutely not be exceeded on this input! It can damage the battery charging circuit. Less than 5V will not damage the battery charging circuit.

Thanks,
