I'm in the middle a building a large battery using 18650 cells. While saving money to afford a $500+ Batrium BMS I've been looking for some cheap BMS solutions for the time being. I have came across a few cheap BMS is and I've noticed a similarity between a lot of them. a lot of them have a lot more room for more mosfets then are currently installed. from what I can tell all the mosfets are in parallel. I've included a picture and was wondering if one could install as many mosfets as would fit and if doing so would raise the current capability the BMS.
I'm thinking that adding more mosfets would allow the BMS to handle more current as long as I beefed up the traces with extra solder or wire leading to the pads for the load and battery connections. and if you notice the required resistors or components are already installed next to the missing mosfets.
if doing so would not raise the current capability then would it have any other benefits?
