big thanks to Maximus for sorting out a lithium battery for the barge......FMD its light but 290 CCA in a box not much bigger than a pair of 50's ciggies boxes.......I am amazed. Am looking forward to seeing how this little jigger goes at cranking over the barge.....
Given the weight of this battery - only 900g or thereabouts - its got me thinking about using these as the base for battery 'packs' in the electric bike - which from here on in will be known as the GPz72v.....
6 batteries per bank, 6 banks in total - each individual bank wired in parallel, all six hooked up in series - would see 72V @ 10,400 CCA !!!
hmmmmm total weight would only be about 36kg including the frame. This is the weight of only 2 large 12V lead-acid AGM batteries....
time to do some more thinking......
