PING! Known to use good prismatic cells, known to have less defects, known to be extremely helpfull in the rare cases of a defect, known to deliver advertized amp hours, known to do at least 2-3 hundred cycles without noticable loss of range when used under 1.5c. Or,, take your chances. Ping has good prices on his own pingbattery website, if you didn't already know. I have heard no evil about volgood, but if he is not using high quality prismatic cells, it just can't compare to pings batteries. Yes there are better cells out there than ping uses, but not at that price, and the bargain packs usually use 18650 round cells, that seem to have gotten a reputation for individual cells going bad pretty fast.
By the way, surely somebody has more cycles on a Ping version 1 battery than I do. Anybody got to 500 cycles yet? And how is it doing? Mine has around 200 cycles now, 90% to about 75% dod. Other than the cold, no noticeable loss of range.

Toyiko, if you are using a big motor, like one that draws over 30 amps while riding full speed on flat ground, you may not get the lifespan you want out of a Ping battery, unless you have one made that is bigger than 20 amp hours. Mine is lasting well since my motor only draws an average of 20 amps while I ride full throttle. With the less expensive batteries I think keeping the battery big enough to only draw Ic out of it is crucial. So the rule of thumb is, one amp hour of size for each amp the controller uses while riding full speed. That is not the same thing as the rating on the controller. My controller is a 35 amp, but while riding full speed, it delivers just about 20 amps, and only puts out more on hills and starts.

That should be the right size. I couldn't remember if you had a big crystalite or something else that needs bigger amperage than a ping can handle.
