I purchased 3 x 200Ah (12V) Smart Lithium batteries to replace the AGMs on my boat. Also purchased the VE Bus BMS v2, Lynx Distributor, and already have Cerbo, Multiplus, etc. The batteries are to be connected in parallel.
Section 4.6.4 of the Smart Lithium manual has a schematic showing connection of parallel batteries individually to busbars with a fuse on the positive cable (for cable protection). Question: could this be a MRBF fuse on the battery post? Would a MRBF fuse be better than using a Mega fuse (has much higher Interrupt Capacity)?
Further, this section also states that "connect the cables diagonally to ensure equal current path through each battery". This arrangement would be far easier (than the busbar method) in my constrained location. Is this equally acceptable for paralleling 3 batteries? And can/should I place a MRBF fuse at each positive terminal post (I have never seen a schematic or video of this!), or simply connect the cables post-to-post, and then have a T-fuse (or ANL fuse), very close to the batteries, on the cable to the Lynx Distributor (for DC Loads & Chargers)?
Thank you for feedback and suggestions.
