The Current Spec Sheets say not to... Have seen too much evidence that proves it is not wise, especially when adding compression into the equation. The latest Seplos Standing Kits comes with special spacers (polycarb) & foam to put between the cells to provide the buffer they require for such an installation to alow the cells to actually have the space to expand & contract through their normal cycles. Sadly I just watched a video that borked the install process, over compressed the cells on their side which WILL inevitably lead to gross failure... Sad that some just do not have the common sense they ought to.
1 EVE 280AH cell weighs 5.6Kg /12.3 Lbs.7 Cells weigh 39.2kg/86.4lbs and you are putting THAT weight on top of the bottom cell. (without extra compression).
REALLY PEOPLE ! The Prismatic Cell Case is NOT ANY THICKER THAN A POP CAN ! You can squeeze them and get flex between your thumb & index finger.... Give them a shake and you'll hear slushing sound from the electrolyte within (as it should). Prismatic cells unlike Cylindrical cells have No Strutural Strength.
SERIOUSLY: How Obvious is it that having a stack of cells the bottom "one cell" will have to carry all that weight on top.. Then to further "compress" them, it is completely IDIOTIC... Come on, Kids in Grade 7 Science class know about cumulative weights & pressures...
Andy's Garage just showed HOW NOT TO INSTALL THE CELLS and over pressure them....
YouTube expert learning while doing, doing it wrong and getting his followers to do the same... Rather than sitting down and engaging Critical Thinking" as to why kit parts were included spacers etc and that when used properly would have held the cells "properly snug" and with the Mid-Plate (was missing in his kit) installed there would have been no heavy pressure on the bottom... Surprised it didn;t squoosh out & leak when he crushed them down with the plate - give a few days & some charging... for him to learn th stupidity of what he did. HE WILL NEVER ADMIT IT !
