So I've been educating myself on these ebike battery pack designs, and once again YouTube has been my friend.
From what I can tell Lectric could easily offer an extended-range battery pack by using 18650 cells rated for 3.5Ah rather than 2.4Ah. One fellow on YouTube did extensive tests with a dozen brands of 18650 cells and found that (1) Chinese cells were junk, and (2) Sony and LG made cells honestly rated. And the LG cells were relatively inexpensive.
So it seems to me it would be easy to simply build new packs with branded high-capacity cells and you'd get 3.5Ah x 4 = 14Ah, or 14 x 48 = 672 Wh. Even a bit more than that if there was room for 14 battery packs rather than the standard 13 (would make a "52v" battery which apparently is within the tolerance range of 60v controllers).
I've only had my two ST Lectrics for a few weeks, but mighty impressed. I've turned off the PAS completely and rely on pedal and throttle as being far more controllable in traffic.
