Tow vehicle not charging new lithium battery

On another note, I hate that the battery switch has to be on for the Ebrake to work.

The only justification that I can come up with is that it gives us a way to release the brakes after they have been activated and you can't reinsert the pin. Of course a better way would be to have a separate emergency brake switch to bypass the pin switch.

Or add a utility trailer ebrake battery backup box, about $54.   This one has self test and charge lights.  Charges from tow vehicle or cross charge from nucamp I guess.  Probably would need to address higher LiPoFe trailer battery voltage state with some sort of intermediary device.
