200ampCurrent?
High current BMS are challenging. Personally, I would likely split it into 2X 8S batteries each with their own 100A overkillsolar BMS on it.
if you put the 2 sets of 12V 120 amp BMS in series to get 24V with this solution you are limited to 120 A ?Agreed. That's what I did. Two 4s batteries, each with a 120 amp Overkill Solar BMS.

This makes a lot of sense to me as an electrician I've seen what breaking high current ccts does to contact faces. Also it allows all cells to be monitored via BMS. Problem is I'm in the UK and doubt he is shipping this way..???2X 8S batteries, each with an overkill 8S BMS, in parallel could handle 200A. Additionally, the overkill is rated to 100% duty cycle (you don't need to de-rate from 100A), and it's very over-current tolerant.
i was thinking you want to go 24 V , so you have to go in series with the 2 sets and that solution is not good for youThis makes a lot of sense to me as an electrician I've seen what breaking high current ccts does to contact faces.

This will never work, the 'device' rating is still only 12v/120amp. You cannot double up 12v loads/devices/resistances to work in 24v mode it's only DC power sources (Batteries) that you can 'series' up..... Ohms law anyone....????if you put the 2 sets of 12V 120 amp BMS in series to get 24V with this solution you are limited to 120 A ?
