I think the Bionx uses Lipo batteries. I think you get more charge cycles from LifePo4 but I'm not sure.

Yea... I haven't really been paying too much attention to price. I was fairly confident the price *was* higher because of the two main benefits for choosing Lithium Polymer: smaller size, and more recharge cycles. More money or less, it's worth it.

I believe my mind has been mixing up Lithium polymer & LiFePO4... I don't know what to believe anymore.

Rechargable lithium batteries come in 3 flavors right now..
- Li Managnese
- Li Cobalt ( often called LiPo )
- Li FePo4
BionX uses Sony LiMn 18650 format cells ( similar to laptop cells ) btw.
Li Cobalt , the 48v 10ah pack that puts out 100 amps that recumpence talks about, is great.. best power to weight.. only potential drawback and i think this is why it's not as widely used in ebikes.. = safety. If you don't treat them right.. abuse them. over discharge.. over charge.. etc.. they can go up in flames.. quite spectacularly at that... however.. that being said.. treat them right and with respect.. they are quite good !
In RC world, most people use milliamp hour packs.. at moderate to low voltage.. but on ebikes. you get amp/hour packs at higher volts.. like matches vs dynomite..
LiMn and LiFe, claim to be " safe " .. even if abused.. you may kill them prematurely but they are not supposed to erupt no matter what.
LiFePo4, now .. this is a whole new world of lithium.. lower Voltage per cell, more weight per ah.. but.. if the claims are true, they should last alot longer than the rest. still remains to be proven.
I've used them all.. and peronal preference at the moment is LiMn.

Well after much soul searching, I have decided to give back my Ebike.
The electrics had an issue that I couldn't fix.
Much credit to Steve from Zbike.
The guy has offered help all along the way.
