The dimension enginering one wont monitor all 4 cells in your 2s2p pack either. It will only read the voltage of each parallel set. The way I understand it is, in paralell the cells tend to seek a level with each other which is why lipos that are 2p or more are only wired to balance the voltage of each parallel set of cells vs the other parallel sets.

If you balance your packs regularly using a standard cell balancer when you charge them you wont have any problem using a cut off that just goes by the total pack voltage.
