Hi guys just converted from battery to ultra capacitor on my 2011 ec300e, the reason behind the move was expense and durability.
The original battery leaked causing minor damage to the air filer underneath, lithium batteries are expensive and my local bike shop refuses to sell them due to the amount of returns due to charge issues(poor bms).
The lead type batteries are reliable but heavy and the weight is carried high and again quality unit is expensive.

Bought a discontinued mb3765 model jump starter from jaycar for $50, ripped out the capacitors and wired it into where the battery would be.
This system is ideal on this model bike due to not having to charge the capacitor prior to riding, simply kick start the bike and it charges from the stator after its charged you can use the button or alternatively charge the caps before riding.the caps give 250cca and weigh around 600 gramms and should outlast the life of the bike.

Just posted this on a whim if anyone is intersted i wil post pictures and a ride report.
