Some of my setup modifications i have made are:
Placed a layer of compressible insulation between the battery cell faces.
Installed 6mm to 10mm aluminium flanged studs on cell terminals. (All connections torqued to 4Nm)
Installed flexible braided busbars across cell terminals and from cell pack to fixture points, thus relieving stress on studs due to movement.
Installed a three point compression fitting applied to a flatplate to distribute compression evenly, rather than application on the outer fixture bars. Belleville washers centred over non threaded bolts(so no thread hang ups or galling).
Created a relay board with SSR's to directly control the remote on/off functionality of victron inverter and SCC(such that i dont need contactors) using a Chargery BMS. Also powers down the BMS in the event of an over discharge event or low temp disconnect. (Uses the BMS two signal assistant on inverter/charger).
Installed a three point disconnect switch with inbuilt precharge circuit for inverter surge protection on initial power up.
Installed a seperate disconnect switch on the negative line, to completely disconnect everything bar the two shunts.
Chargery shunt only used for OCP. Chargery BMS externally powered to maintain most accurate voltage measurements of all cells.
Victron shunt installed to accurately monitor pack capacity.
