Here is the starting battery I've made for the MGeo.
I'm using the A123 26650 2.2ah cells, soldered them up into 3 in parallel, 4 serial, for 12v, and made a plastic box to hold them tight.
max 210amps, and 6.6ah. The G10 seems to draw less than 100amps
when starting, the lithium battery has no problem at all.
You can see how tiny it is, it weighs less than 3.5lbs! And I can fit it right next to the starter tucked in down low next to the frame rail.
No active controls, just the bare cells, so it charges from the 14.50 of the alternater, and can be discharged without limit. Well see how long it will last, the cost was only about $120ish, so not too expensive really for saving up to 30lbs of weight.
