From 1091354c0eadc65ab86b814e85d26960058d8e3f Mon Sep 17 00:00:00 2001 From: Aseda Aboagye Date: Wed, 30 Sep 2020 15:08:44 -0700 Subject: waddledee/drawcia: Update default resistance The default combined Rbatt resistance is actually higher than what was currently specified. The wrong Rds(on) value was used as well as the sense resistor was missed. This commit updates the default resistances for these boards. BUG=none BRANCH=none TEST=Build and flash drawlat, verify default resistance is updated.
