Lynx Smart BMS sizing and fusing with Smart 330AH batteries

  1. 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.
  2. 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.

  1. 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
