- The decision on the BMS rating depends on your planned maximum power requirement. For example I have 12V 3000VA multiplus and maximum 12V loads of 100A so i am using the 500A BMS.
- The mega fuse has too low ICC (AIC). Class T is suitable. There have been some recent posts using Adler EF3 fuses in a Lynx distributor. The fuse rating depends on the wiring rating, the max battery discharge current and the max power demand. For example I have 2 x 300Ah 12V Victron NG batteries in parallel with a 300A Class T fuse on each battery with 350A rated cable and the Lynx NG BMS is rated at 600A short term.

- The battery protect on DC loads is optional. For the Victron equipment MPPT, Multiplus etc) there are 2 layers of protection, DVCC control and the contactor. If you fit a Battery protect from the ATD signal tjen you have 2 layers of protection, plus you can drop some loads before the contactor opens, hopefully keeping the BMS and GX device on line for a longer period. You could just rely on the contactor. I have a Smart Battery Protect.on my DC loads.k
