Hello. I'm going to buy a lithium battery kit or hire someone to build a pack for me. I don't want to get lost in the weeds over exact products, but wanted to know more about higher level construction methodology suited to my intended use.
The LiFePO4 battery would be used in a 23' long Sprinter 3500 based motorhome vehicle that's heading out from SE USA to South America for a 2-year, 40,000 mile trip. I'll probably endure 15,000+ miles of gravel corrugated roads in average to poor condition, compared to US roads. The battery is in a "step-well" battery compartment typical of Class C vehicles at the entry door. Weather conditions will range from 105F to -10F, so the batt would be heated. The battery compartment is closed (not open to the elements), well insulated, vented into the vehicle (with fans) and designed to house batteries.
QUESTION: What's important to improve durability? Should I be thinking about a particular type of bus bar, cell compression method, etc? I have no idea.
I could not find a "pair" of batteries, that would have offered redundancy, to fit. I need at least 300AH total energy storage. I'm not fond of having only one battery, but since this seems to be my only viable option, I'm thinking a "kit" or custom build battery would be best. Because I can repair it if it breaks and maybe take an extra BMS and a cell, or whatever makes sense, with me in the spare parts locker. At least this makes me feel a little more comfortable since all my eggs are in one basket with a single 300 amp hour battery. I hope this makes sense.
Thanks for any thoughts.
