I'm an e-bike enthusiast & small E-BikeKit Dealer in PA. Although I have a web-site through which I sell E-BikeKits & bicycle accessories through amazon the only "real" income I make is selling the e-bikes I build using Jason's kits, Ridekick trailers. & service & repair work. This year I really want to get away from lead cells & use almost exclusively lithium batteries. (a pipe dream I know)
Although I don't post much I've been an avid reader of this forum for some time. As a matter of fact everything I know about e-bikes & lithium batteries I've learned here... & I still don't know nothin.
Without getting super deep into the various lithium battery chemistries I need some help in making a decision on what to order & from whom.
At this point I'm down to trying to decide between LiNiMnCo & lifepo4 & USA or China.
So my specific questions are:
What is the difference & advantages/disadvantages of LiNiMnCo versus LiFePO4? I've had good experience with Headway LiFePO4 batteries.
Are batteries sold as Li-ion batteries actually a unique battery chemistry or simply a generic name for one of the many available lithium chemistries?
Is there another battery chemistry I should be looking at?
Has anybody ever used battery packs from Xincchi Photo Electric Co. http://xinchibattery.zxq.net/? I've now had several email communications from them & they have been extremely responsive, helpful & understand our language perfectly. I've had mixed results from other Chinese vendors & don't like the unfair advantage they have over US manufacturers. I.E. little or no liability worries. The language barrier has also been a real problem. But even with a healthy freight charge the price savings is substantial enough that I can't not consider them.
Personally I'll spend $200 more for a US built battery in a heartbeat but when your starting out by trying to up-sell a customer lithium over SLA & then add another $200 for "Made in the USA" on top of that... well, it's tough.
My serious contenders, a side from Xincchi at this point are: Batteryspace, Ping & Headway Headquarters (a US Headway seller builder). I'd love to try the Allcells from E-BikeKit but there not even in the ballpark with their prices & as neat as their PCM technology is I think it's over kill for an e-bike.
I only buy 10 batteries at a time so I'm not exactly getting container load pricing.
Thanks for any help you can offer me.
