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)Which option to choose depends on PSU
We’re using the 12V PSUs that are currently wired to the chargers. What is the output power rating?
How much current do the batteries need to be charged with? Charger has 4 channels, up to 15A each
