Anyone else charging their ST16 battery on a regular lipo charger? I'm curious because the readings I get from the ST16 (in pad mode), a battery tester and the charger don't match up. Here's the readings I got: 51% left in pad mode on the ST16, 35% left on the battery tester (HK-010). When I charged it back up, I put in 3140mA which is about 36% - 3140/8700 (64% left). I know the battery readings aren't totally accurate, but these are way off. Maybe this battery isn't actually 8700mAh. Anyone got a clue?
