DIY Expedition Camper large Battery System: Modifying Fuse Blocks

I cut down the studs on some Blue Sea MRBF Fuse Blocks to reduce their height for more clearance under my raised floating floor above my large 1,800 amp-hour lithium battery system. I have three pairs of 300 amp-hour battery strings in series to raise the voltage to 24 volts while the max current from each battery pair is internally limited to 200 amps. With that much potential power from each of the three battery pairs, I want to make sure that the wire directly from each battery pair is protected on its way to it's fuse on the Victron Lynx Distribution system, so I install a Blue Sea MRBF fuse block on each battery post and then install the large 2/0 battery cable to the Lynx distribution system for my DIY expedition camper's electrical system.
I installed six 300 amp-hour Chins lithium iron phosphate batteries and four Victron Lynx Distribution busses all connected as one main 24 volt distribution. Between each battery pair and the Lynx I installed a Blue Sea ML-RBS (Magnetic Latching Remote Battery Switch) which allows me to disconnect any one or all of these battery pairs remotely for safety when accessing the raised floor to inspect the batteries or in an emergency shut down. Being able to disconnect these high-out batteries from a safe distance is a very nice feature.
Recent videos show battery cable wiring, battery testing, and lots of other details about my DIY expedition camper build underway.
I recently built this Total Composites expedition camper on my Mitsubishi Fuso EarthCruiser CORE 4x4 expedition truck chassis, and am finishing out the interior cabinets, electrical and plumbing systems, and about to paint the entire exterior of this camper and the cab.

awesome. any considerations for maintenance (6mo re-balance) or replacement? does the top frame come off easily, how would you get at the batteries in the back?

[@vantripping]

Yes, the floor frame easily hinges up and can come off, but I see no need for any maintaince, since all battery pairs have equal length connections and share of charge and discharge currents, temperatures, etc, they should all last ten plus years without any issues.
