Project goal
Unlike powerbanks based on custom ICs this one called for a generic system which could support different types of batteries - li-ion, LFP, LTO or even lead acid.
Solution
To do this we had to get back to the first principles of power banks. Get generic high power charging circuits and then input voltage agnostic discharging circuits. The device supports 10W charging and 15W discharging on each port along with safety circuits and a custom charge indicator.
