well that blows my mind. i thought the 29 amp limit was for the motor to regulate current from the batteries. guess i was wrong. i just didnt want to see that yellow light flickering when it comes hot off the charger and im trying to get it moving at full throttle anymore.
dequinox wrote:Hey def,
Hows that bike treating you? Everything working out alright since the little battery incident you had? Amberwolf is right about the SLAs...you don't want to use them at 30amps for very long. They tend to crap out quickly. I've been keeping my draw at 20& below and getting about 5 miles before the performance noticeably drops off from my 12v12ah pack. The day shall come soon when I invest in lithium!
amberwolf wrote:Depends on the motor, controller, and batteries, but I know it works that way with the DayGlo Avenger MkII's Fusin hubmotor and NiMH pack, which is only 36V 9Ah. The controller tends to limit peaks to around 16A, but that's a lot for a 9Ah NiMH pack. If I help it by cranking during startup, too, in a nice low gear, I can save a lot of power--probably at least a couple of Wh per mile. Problem is, that's tough on my knees, so I let the motor do almost all the work, and live with the Wh loss.

id like to try and get a pack for my bike because im not ready to go lithium yet, for financial reasons and for the fact i tend to be neglectful(i forgot i left a soldering iron in the wall overnight the other day. imagine if that was a lithium battery, that situation couldve turned out bad )
ive ran across a thread knuckles made about building a NI-MH pack out of 10000mah tenergy and powerizer cells and said he had good results out of them. id like to try and do that but everyone doesnt even look at them and say just to go lithium.
dequinox wrote:Nice! I'm about to go up to 36v myself, can't wait to try out the higher voltage. Unfortunately I'm still stuck with lead for now... but I'm looking at the Foxx Power cells from ebay...and purchasing one of their packs. I figure sure I could save about $100 by assembling it myself...but it looks like they do a good job so I'm going to differ to their pack-building skills. Knowing me I'd melt a wrench!
amberwolf wrote:Well, that's good (the offer); I've had stuff broken (or lost) that I loaned out, with no offer to do anything about it. When I've broken stuff I offer to repair/replace it, most often they turn me down, having loaned me the old worn-out tool in the first place.
I guess it's different if it is something you *expect* to break anyway, like a lot of stuff on CrazyBike2 I figured would fall off every time I started riding, but didn't. Also didn't break whenever I had other people ride it. (though most are afraid to get on it because it doesn't look/ride like a normal saddle-bike, and some because it looks like a pile of junk. )
