Well thats the crux of the problem. With Chevron's actions its illegal for me to have larger batteries (ok there is one slightly larger but the cost of this cell is so much more than the D cell its not worth it and would NOT appreciably reduce the number of cells I would need but would quadruple the cost.)
Well there is no "larger" nimhs for all intents and purposes that I am permitted to purchase. so its D cells or no NIMH chemistry sadly.
The issue is "CAN" it be done. if an effective way can be found to charge them affordably I would like to at least try. Small scale first off course.
The advantage of nimh is I can use almost ALL the capacity (50% of the mass of leads is dead weight because you can not go below 50% capacity without gravely harming the cells. Nimhs do not suffer from this.
Nimhs will also last a lot longer. SO the time from pack to pack replacement will be a lot lower.
It also means I can buy in lots and slowly upgrade the pack.
I m just trying to find out if it CAN work. IE what kind of amps to I need to move say 3000 pounds 60 miles on typicaly relatively flat terrain with an average speed of 45mph.
I have no idea how to figure this out.
