But with respect that's 12 volts. I want 13.8. Plenty on Ebay for not a

The most popular official voltage is apparently 13.5VDC, not 13.6VDC.

13.8 is the usual voltage on a car with the engine running and things
stabilised. But of course most equipment will tolerate a wide range and
still work.

I like 13.7.

14.0 volts is the best. You will lose a tenth or so in the leads and
connectors
