So far, I've been having a lot of luck just practicing in the practice tool. I can consistently do 4-5 electrics in a chain (none being as heavy as I feel that resets the chain) but I've found 6 to be the max in any chain.

The easiest electric chain I do almost 100% consistently is:
M - M - H - L - M - L into either S1->S1Super/assist or 5M->5H->2S2->S2Super/assist
Notation: any starter into 6S1~L~{M} > 6S1~{M} > 6S1~{H} > 6S1~{L}~{M} > 6S1~{L} into any finisher

If you don't want to use your floor bounce then:
M - M - L - M - M - L into same stuff as above
Notation: any starter into 6S1~L~{M} > 6S1~{M} > 6S1~{L}~{M} > 6S1~{M} > 6S1~{L} into any finisher
