From a comparison of price/how long they last each charge/life?

Several ev manufacturers use the AGM type of battery. Zenn, Miles and a few of the Smart car Chinese knock-offs use AGM, professional judgement. Consider that the lead-acid battery is completely recycled, lead, acid and plastic. The AGM is sealed, no maintenance, lower sulfication. Cost is about 3X the flooded cell, less than 1/2 cost of Lithium. Safety is a big issue with flooded cells. The AGM battery size is considerably smaller.

For comparison of Cost/Capacity/Life look to golf carts. Batteries optimized for this industry are well suited for EV use. They are almost always flooded lead acid type, mostly 6V.

with the research i have done the best battery is the NiMH the reasons are they are the a fairly light, have long range and have a life span of 5000 full cycles
the only disadvantage is that they are hard to find a place to purchase. one place to get them is in a Toyota Prius.

That's because Cobesys who is owned by Chevron and Texaco own all the patents and I don't think they are planning on giving out any licenses any time soon.

Hi,

We think now the best battery for ebike is LiFePO4 battery.
It can use a long time and no pollution.

Hi cammycc,
I'm very skeptical with Chinese made products. The product quality sucks. Do you have any unbiased/unfiltered testimonials regarding the quality of your product? I'd rather pay double the price for Japanese, EU or US made quality products.
