serv13: Correct battery charging limits #462

Open JBombNZ opened 3 months ago

JBombNZ commented 3 months ago

The battery on the new serv13 takes forever to charge. The limits are set at src/board/system76/serw13/board.mk line 40 to 2 amps. I have doubled this to 4amps and flashed it to my laptop and its now a lot faster but still 2 to 3 hours to charge at about 25W.

Can System76 finish the config for this laptop. It has a # TODO: actually bq24800. The bq24800 data sheet says it can do 8 amps but I don't know if the battery can handle that. What is System76's recommended configuration here?
