been talking about this for years with different people on occasion but ive never done it until now.
This is a sectional, removable pack that can be broken down easily. i set it up in 2S 4P sections that can be plugged into the harness in any order. The magic is in the harness, with XT60s for the series connectors and XT30s for the balance leads. The harness makes it next to impossible to plug the pack in wrong, and it doesn’t matter which one goes where.
This method could easily scale to any sized pack.
