TLDR: Excluding ventilation, price, and weight, what’s the downside to adding a couple 3kWh+ portable batteries (Jackery, Ecoflow, etc) in the remaining trunk space to charge when not around a station?
Short story long:
I’ve seen a couple folks mention swapping out their hv cells from the HVB to get better efficiency, but haven’t seen anyone post pics of it actually being done. I live in a place where there isn’t a good free/cheap charging network and travel just far enough to work where I switch from full EV. Good 3kWh+ portable battery stations have a 30A connector plug if you needed to get a low level-2 connection to charge quicker, but with 7+ hours parked, I’d might as well just use the level-1 to pull from the 2 portable batteries stations throughout the day with a neutral-ground plug and the charging cord. Yes, I know it’s, $2.5-3k each and I’d need two that would take up the remainder of my unused trunk, but my company won’t put in a station even me and the other EV guy offered to split the equipment cost. I also go camping a lot and the portable packs would be a great upgrade when I need the 4x4. Again, other than the initial cost, trunk space, and ventilation, what are your thoughts?
(As far as weight distribution goes, they aren’t even 100lbs each and that’s not a significant factor even when accounted for securing them in the back seats or floorboard then putting them in the trunk when parked or just leaving them in the trunk the entire time.)
