Hey guys, I’m about to look at building a 10S4P pack using LG HE4 cells. I’m wanting to be able to take my board on planes so I’m looking to build the battery in such a way that it can be pulled apart into 5 separate 2S4P packs to take in carry on, then easily be plugged back together via bullet connectors or similar.
I was originally looking to solder the cells together with nickel strips but the only place I seem to be able to find them is on Aliexpress where shipping takes close to a month to get to NZ without paying crazy amounts for shipping which isn’t really ideal so instead I’m thinking about using 12 to 10AWG bare copper wire, preferably stuff that’s made out of a few strands at most to increase rigidity.
As I don’t have room to use plastic spacers between the cells, I’m thinking about hot gluing them together into two parallel groups of 4 cells, possibly along with bamboo skewers running down the gaps between the cells to help strengthen the 2 groups. Each pack will then be covered in the same sort of heat shrink that’s used on Enertion’s space cells.
I may also look at adding a fuse between each of the 5 packs, possibly the same 40A blade fuses that the space cell uses?
Would be interested to hear what you guys think about this idea. Cheers
