Extra battery

Currently, I’m thinking of a way to fit multiple 18650 cells into a housing that would go along the width of the laptop and use only 2 expansion card slots (one on one side is only for stability) with a Buck-boost converter to convert the charging voltage to the appropriate voltage. For this, I need to know the exact voltage it requires.


@Kieran_Levin mentioned here that there is an internal buck-boost capable of 5-20V.

Yep so that makes it a bit easier.

@Samuel_Murray I thought the same thing but was corrected on DC plug expansion card for compatibility with more power adapters - #7 by GameFan
