I would like to charge my Li-ion battery from Dyson V6 vacuum cleaner with my solar system/controller (12V output voltage) with a step up converter 26.1V/3A. I already charge my apple computers and ipad pros, and all the other electronic stuff, which are all tolerant to current, as they handle current control themselves. However this one is trickier:
The original dyson poweradapter states 26,1V and 780mA. To step up to 26,1V can be easily achieved, but what about the current? My current step up module limits current to 3A. Do I need to limit the current somehow?
I appreciate any feedback. Would it be safe if I step up to 26,1V e.g. with a maximum of 1A only? Or do I need to fit the exact data stated by the original poweradapter?
Kind regards, Alex
