The maximum continuous discharge current for the BMS is 30A The over current protection current for the BMS is 90A 30A discharge current above to all controllers' limit current Varstrom used on the conversion kits. So, all the battery from Varstrom with the same voltage to Varstrom's kits will be the best combination. You can also use you own batteries, just make sure the discharge current below 30A. All BMS protecting functions includes Over current protection Over voltage protection Over load protection Over charge protection Over discharge protection Temperature control protection Short circuit protection Cell voltage balancing More Details for the Battery Case There are more details on the battery such as Voltage Indicator Board (Shows the voltage range for the batter, not the percentage capacity for the battery). XT60 Socket Connector, Charging Port, Switching Button, Locking Keys, USB or Type-C port, etc. You can refer to the option image for the details of the related battery.
