Thanks Ron, and amberwolf, sometimes I stare at a design so long that I can't see the obvious.
Thanks ambewolf for the Aussiejester link, Ive seen those benders at HF, but always thought they were a bit
wimpy looking,.. good for small stuff. It's amazing that he was able to bend the large tubing.
He has amazing building skills! Beautiful bikes. Gives me hope.
I'm thinking that between one of those benders and a curved wood bending form, I should be able to do it.
The curves are pretty mild. The top and down tubes are the problem tubes, the small tubes are easy to bend.
I designed this battery case for the big Milwaukee 12ah batteries, but got to thinking that maybe I should take another
look at the 18650's option. Probably a lot cheaper than the packs, and possibly more Ah with single cells,..plus,
a lot thinner profile, at only 3" wide. I'll have to give up the one hour charge though.
I don't know a lot about them unfortunately,.. having spent all my time with drill packs, maybe you could suggest a
good choice for a cell,..Panasonic? Samsung? 3000ah,..3400ah? Whats the best value?
Meanwhile, I'll start searching the ES for battery pack builds like this.
Keep in mind, I'm just thinking about this.
I drew up a mock fitting to see about how many cells would fit in this case,.. so that I could keep the option for both,
and came up with about 150 cells. Perhaps I can't pack them that tight? Need room for end caps?
With the 3400ma cells.
At 37-40v, it would be 15 sets of 10 cells, 10S-15P for 51ah.
Or, at 55.5v it would be 10 sets of 15 cells, 15S-10P for 34ah.
Both of those would kick the drill pack's ass,.. any insight to all of this?
I know I have to tackle the BMS's yet. I'm just thinking out loud at the moment,..feel free to shoot it down.
