  Batteries and whatnot

  I guess an advantage of using one lithium battery at a time is reduced weight - no reason to bring a backup lithium if you're only going a few miles.  Is this why you changed the original plan of using the lithiums in parallel?  Or maybe that's still the plan once the SLA's are spent?

  In theory adding an ultracap bank in parallel could result in better acceleration and reduce load spikes on the batteries, resulting in longer life.  I've not tested this in practice, though.  Have you considered trying something like this?

  The ultracaps are expensive, but I'm less concerned about today's cost than seeing what can be done with tools that are currently available.  Costs should come down over time.

  My 'ideal' bike right now (starting with my old steel-frame mountain bike) is something like a few of these 36v packs in parallel with an ultracap bank, perhaps with a controller to balance loads.  How close we get in the real world remains to be seen...Thanks again for sharing your experience!On A home-built electric bike is working like a champ posted 3 years, 2 months ago 35 Responses

  Thanks for the update

  Enjoyed reading the progress you've made on the bike - I've been trying to figure out something similar, and your battery/cargo carrying solution seems one of the most effective around.

  How do you secure the batteries while you work/shop/etc?On A home-built electric bike is working like a champ posted 3 years, 2 months ago 35 Responses
