I am looking into a method to charge Li Ion batteries arranged in a 3S layout. I have a BMS board already connected to the batteries, but I then read that it does not handle the current limit input, meaning it can suck down as much current as possible. amazon link to bms
I looked into the documentation on the page but it is quite sparse. I am trying to feed 3 3500mAh batteries in series, 3S layout connected to a 40A bms. I am looking at a way to fill these batteries safely. Can more information be provided than what is in the documentation about how to use it and if it would fit my needs.
You might consider using a RC battery charger rather than using the BMS for charging. Something like the product in the link below would be safe and reliable for a 3S battery.
You could still use the BMS for your load though. I’d rather go with a reliable purpose built charger than a random chinese board off Amazon since these type of batteries can fail in spectacularly firey ways if not charged properly.
Thank you for finding that device. That is the type of thing I have been looking for. I need to read up a bit more about it as I plan on embedding it inside my robot so I don’t have to fiddle with it, but it is at least a start
