I asked her she said she didn't have a spare pack at hand so yeah.

Great post, I think I will go with the Headway packs, Victoria said they could custom shape them, and a 60v 20ah pack is just $90 more than a 48v pack. Which is more 'fuel efficient'? Using my 60vbattery, 48v motor, at 20km/h, or using a 60v battery, 60v motor, at 20km/h? I'd assume that the...

I got a price quote from Victoria about the headway packs, the difference from 48v 20ah and 60v 20ah is only $90. To run 60v I'd simply need a controller upgrade correct? (To be safe, as I think my current one will run it fine) But what about my motor, my 48v motor? Does a 48v battery have the...

Yeah you should see my suitcases when I come and go from the US. xboxes, laptops, iphones, ect.

Well I drew it on paper, I can fit 9 batteries in the current box, and maby stack the rest in the seat area. Some bikes around here have the tall SLA configs, where it's just SLA's stacked on top each other, and they go under the seat of a traditional bicycle type EBike. (Mcdonald's delivery...

Yeah the picture made me realize, with my current box, I can only tetris like 9 cells, in, and still need to find a place to stick the other 7. I could split them into three batteries I think, or make a small 2xSLA sized one, for 'tucking' into the recess, and then a 'tall' one so it can stand...

Wow that's huge, thanks for the pic, helps a lot. I think I'll go with these, they seem to be more plug n play. What voltage are these packs rated at? I mean, I know they swing from 2.7-4v, but what figure do I use for building, are these 3.3v also? When I build my pack, what baseline voltage...

yeahYeah I saw those. What the heck are they? Are they simply a lifepo pack in q ruggedized shell? On there it says they are lifeypo4. Do I still need a BMS for those ? On a diff site it said I did and then told me to buy a $700 Bms. that is definately way in my price range.

So 15S9P will get me to 48v, 20.7AH? I need 15*9, 135 a123 cells? Damn that's like 2 grand. Every 2.3 AH @ 48v costs $135 (using $15 as a base figure) Are the headway and umm ping battery packs using a123 cells, or some other cell? How do the cheaper cells (Chinese?) compare to a123? Other than...

Yeah thanks for the input, I'm going to buy single cells, and make a 20ah pack, all in one go, I don't wanna risk anything going wrong. I'm going to investigate this guy (http://item.taobao.com/auction/item_detail-0db2-863ced6543043cc214ee17c9037073f2.htm?cm_cat=0) He's selling A123 cells (he...

How much mah should the cells I use have? If I took the Headway batteries for ex, I'd need 16 sets of 4 cells?

Ok I understand it better now. I need 15 strings to get 48v and 20 1AH cells to get 20AH?? Is it better to use 1ah cells, or 2 ah cells? Does the AH matter much, as long as I get to 20ah? Does anyone know what my SLA's AH is now, just a ballpark guess?

Well put julesa and scoot, I wasn't quite planning on hooking two packs together, that's definately way too expensive for me. If anything if I got more cells in the future, I'd have the packs rebuilt or something. But I'm still confused on a few things, how many cells are in a 48v 20ah pack...

Wow their literally half the size of my current setup? You are saying that it's be harder for this setup because of the management issue? is that because there are a lot less cells to deal with?

I was looking on the VPower site, and they have (http://vpower.hk/B_LiFePO4/48V_20AH.html), another problem I have is that My battery box is 18cm Tall, 18CM Wide, and 30CM long, and the OPENING, for that, is 18x18x15, since I have two batteries, it's no problem, drop the first in, slide it...
