This is a perennial debate. I’m building my own BMSes so channel capacity isn’t an issue On cruiserforum it’s long opined that parallel first serial second is best But looking at this recently for a future boat install 300AH , 12V 3 x nominal 12 batteries , ie 4s3P Advantage Each “ battery...

Hope this block diagram is visible note it’s not electrically perfect This bms is based on a battery by battery basis in this case each battery is 4 series cells resulting in a nominal 12v 100Ah battery The bms has a high side mosfet disconnect and uses an ATTINY connected to a dedicated...

I just looked at the video re the BBMS system First thoughts Hmm. Ok for big lead and small li. Not good as a solution where the only lead is a starter battery. Not ISO compatible so that’s Out for European Boats. ( that’s ok cause he doesn’t ship ) My own view is a system that actively...

Im looking at a bms project for my boat , so will design one around the esp-32C series which is RISC V based standard features * 5A switched capacitor based top balancing * CAN, wifi and BLE interfacing but no idea what protocols to do ( possible Victron VE.CAN ) possible RV-C protocol * ISO...

I was looking at my system design for my boats Li solution. Why has the industry not considered isolated dc dc chargers to do cell level charging. On a 3P4s system this is just four dc dc isolated chargers each handling a series string , the cell monitoring could be added as well to the...
