12V to 24V Boost Groundside Converter - Electrical - WARG Tim Gu
Did some math and found a few COTS options, updated confluence page, would like someone to review if the calculations/reasoning is right
PSU is rated for up to 480 W at 12V DC, so for maximum charging capability we would get a convertor that can handle 480 W
Might be able to get this for ~$50 on AliExpress
How fast do we care about charging the batteries? (how much power/current)
