100A or 200A BMS?
For a self contained 12v battery, the enclosure restricts the ability for BMS to dissipate any heating. Most put BMS on top of battery since heat rises. Having a BMS on the side in a self contained battery will transfer heat to cells. Worse is having BMS on side of one cell as it causes more heating to that cell which degrades cell matching.
