Best deal on a 10Ah36V LiFePo4 battery pack?
I'm looking on purchasing this battery for the E-zip bike.
The best deal I have found so far was $568 which includes: 10Ah36V LiFePo4 battery pack in bag+BMS+2A charger ( 6 hours).
I was wondering if anyone has found a better deal?

That's right around what I paid for my 20AH pack.
Someone else posted this link, they may be worth checking out.

I noticed ping is selling several versions of this battery.
What is the main difference between the 10Ah, 12Ah, 16Ah and 20Ah 36V batteries as far as applications for the e-zip bike go?

Now that I've read up a little more carefully about over-volting E-zip Trails bikes, I'd be cautious about using ping batteries to do so.
Too much current draw.
Where Ping recommends operating a 36V 12ah battery at a current discharge of 12 amps, with occasional spikes to 24 amps, that Ezip will want to draw more like 30 amps, with spikes up in the 40s.
The ping pack has over-current protection that kicks in somewhere around 25-30 amps.
You'll be tripping that battery during no pedal starts and going up hills on a regular basis and worse, the ping battery might be worked too hard on a day to day basis to live a long life to see 1000+ cycles.
Although a ping 36V 20ah battery would be better, still you'd be operating it beyond its rated discharge rate of 20 amps anytime you dig deep into the throttle.
Sorry I brought up Ping, probably not the ideal choice in your particular application.
Those falconev batteries look like they could handle the current, but the math seems to indicate, using a 36V 10ah, you'd only get about 10-15 minutes of distance, no pedaling, heavy throttle. A 36V 20ah should double that.

It's on the second page.
I was calculating using a falconEV 10ah battery, and figuring current draw 30-40 amps.

If it means 450 watt output (which is all I would really care about) and lets grant it 85% nominal efficiency, the power input would need to be about 530 watts, or 14.7 amperes at 36 volts, 22 amperes at 24 volts.
In this case we could imagine a 36 volt 12AH BMS-controlled pack to probably cutout from time to time, a 15AH pack may not.

Right now the only LiFePo4 battery pack I'd consider would be one from Ping.

We have just started selling a new LiFePO4 pack we have been working on for months. A new USA "Dealer Friendly" 36v/500w kit that was made to go with the battery pack will be unveiled in the next week or so.

Yeah it does look good. Too bad there are no 48V packs available yet, better yet, split in half for panniers.
