On the Metro
, the front & rear packs have same capacity, so I'm assuming same Sanyo cells, yes.
On the Excel
they will likely be different
cell types, and perhaps not
Sanyos; and forget the Power/Energy thing, sorry, a distraction. What I mean is the following;
I expect front pack(in-frame) will have a higher available discharge(and recharge) rate than the rear pack, probably a higher Amp limit than the rear. The rear pack will never
? power the controller directly; only the front pack will do so. Just guessing that the rear pack will maximise energy density
over discharge rate(see below)?? Or ...perhaps a little LiPo in the rear pack??
Hmm, just found this:
Ã¢â‚¬Â¢ IDEP Technology. Ã¢â‚¬ËœIntelligent Dual Energy PowerÃ¢â‚¬â„¢ system uses a removable, portable lithium-ion battery to store electricity and supply it at a stable rate
to an internal lithium-ion battery for:
- Greater range. - Battery life.
- Ease of charging: the portable power pack will recharge the internal battery. Charging one battery(secondary) charges the other(primary). Ã¢â‚¬Â¢Battery. Lithium ion battery technology. Main battery 48 V; secondary battery 33.3 V.

First time I've seen the 33v reference; what's that about? is it getting boosted from 33v to 48v to charge the primary pack?
One way to isolate the pack I suppose.
As I recall, one or both packs may not be of Japanese origin, though I think they're both from the same company...
Grain of salt time; heard these titbits here and there, so may all be bogus
I think we'll all know the real scoop before years-end.
It feels a little funny being on something light enough to still be a a "Bike" and having feet on platforms, no pedals.
I DO think I could get used to it though.
Just realized I've veered off Metro onto Excel; is there an Excel thread yet?
