When they wanted to make a 1000 amp BMS they found that they had to use 10mm bolts and then that required them to offer a 10mm version of the Lynx Distributor to connect to it.
I think I may have initially thought that M8 and M10 were talking entirely about the connections of equipment and batteries to the Lynx nodes themselves. Meaning I may get a Distributor M8 to connect "smaller" loads such as the MPPTs, but a Distributor M10 as well to connect the multiplus 12/3000. Reading through the installation there is a buried reference that describes the M8 and M10 designations refer to the side bus bar interconnecting to another Lynx node/chassis.
Is that the correct understanding? Why would I ever use the M10 parts? Are the M8 parts also still 1000A capable (asking about 1000A in general, because there is the one BMS 500A (M8) and the Shunt says 1000A but is rated for up to 400A on the negative shunt/fuse)?
It seems all the M10 part numbers end with 10, such as 210 and all the M8 parts end in 00, such as 200. If I've understood the documentation correctly, and nearly all the Lynx parts support 1000A, why use M10 over M8? I'm ordering all new DC cables, so I can make sure all have the right sizing for their current carrying AS WELL AS all having M8(5/16") lugs. Is the M8/M10 mostly only a nuance to be careful of if using the BMS 1000A which is a M10 part and won't interconnect properly with M8 Power-in and M8 Distributor? I don't see any real difference on most of the data sheets except the torque specs on the M8 vs M10 interconnection xxxx .
If I am not using the 1000A BMS, which is a M10 part, I could/should just use all the M8 parts? (assuming I have all M8 lugs for DC loads and battery cables) Is there a limitation to interconnecting the M8 and M10 Lynx parts - meaning if you have one Lynx part that must be M10, then all must be M10 parts?
Based on my 12V system configuration and having all M8 lugs to connect
Configuration: M8 Power In -> M8 Shunt -> M8 Disti -> M8 Disti
Parts: LYN020102000 -> LYN040102100 -> LYN060102000 -> LYN060102000
(In my 12V configuration, I don't need a Lynx BMS and the Shunt will connect to a Cerbo GX)
