can you run 2p using different C ratings?

[WhatRLaws4]

ok, so in short, is the following safe to run?
A 4s 5000mah 40c paralleled to a 4s 5000mah 65c for 4s 10000mah, then wired in series to an identical 4s 40c and 65c confirgurationfor 8s2p?

Better question, would you do it?

Like I said,
Mixing brands is a bad idea.

Only if they were all the same brand cells,
Than yes I would say you should be good to go.

Max amps told me the only deviation from identical is if the only variable is the cells. Say a 3s 5000mah 80c pack can be run in a series with a 4s 5000mah 80c pack for 7s. Makes sense, but i am not an expert.

Only deviation is cells. Brand same mah same c same plugs same friends of battery same
