The best electric vehicle battery choice today for all EV's is a LiFePO4, Lithium Iron phosphate / LiFe. The packs are put together by me. This allows better customer service on any repairs. Servicing a pack made in china resold by other kit sellers is not going to happen.

High discharge and long cycle life make these the premium choice over cheaper offerings on ebay, etc.

Diamond frame battery bag,

a FalconEV Exclusive ! $40

18" across x 11" down, 2.5" deep, 19" frame minimum

Points to look for when choosing a LiFePO4 battery:

Impedance - internal resistance; how freely the cell takes a charge and can discharge

The lower the better. 6 or less is considered good quality

C Rate - Discharge Rate; the multiple of the Ah of the cell / pack

There are 2 types; HE, Hi-energy - Hi-power

HE cells of good quality can do 3 C continuous and 5+ C peak discharge

HP cells ' ' ' ' 20C continuous and 40C peak discharge - a123

example: A low C rate of 1.5 on a 10Ah cell would be cheaper than a higher C rated cell, but it would take 3 X's the Ah size of the pack to = peak discharge ( 50A ) needed by most e-bike controllers

Differences; HE cells have higher Ah rating ex. Falcon 26650 cell is 3000mAh vs a HP cell from A123 is 2300mAh, etc.... HE cells average cycle life is ~2000 vs HP cell of ~1500

HE cells better suited for an range, HP cell better for extreme acceleration, short range purposes.

A typical EV e-bike controller is 30 to 50 amps, e-scooter is up to ~100 amps, well within a quality HE cell capability.

Charging - for 10Ah pack - 3amp = 4 hrs, 4 amp = 3 hrs, 5 amp = 2 hours

Yes, there is a difference, material quality, cell assembly and electronics A cheap low quality cell that only puts out 2 x's continuous of Ah rate is a waste of $. the short cycle life and excessive voltage drop will leave you stranded. spend a little more $ to get a LOT more quality,

These days it is a very rare thing when something is actually better than advertised. The improvement these batteries make over my old SLA battery actually exceeded my expectations. I could go into great detail however I suspect you already know what I mean and you’ve heard it before. Long story short: worth every penny! Give me a couple of weeks and we’ll get started on the other evglobal battery.

Thanks again.

This- from a cheaper quality cell from Headway Co.; notice the lower Voltage levels at each discharge rate, and the early drop off = high resistance

LiFePO4 LiPo

The advantage of using lower resistance, faster charging, no heating, no swelling, higher discharge cells; Is using fewer Ah to meet the peak curent demand of the motor. ie. however many Ah of a thundersky or SE pack you are thinking about, you can use less high Ah cells to achieve the needs of the motor. With the thundersky or SE cells, you are forced to buy more or bigger Ah cells ( at more total cost ) to get this along with desired range. The same can be acheived with fewer / smaller cells that are higher rated. This brings the $/Ah/distance down close to whatone would pay for more/bigger thundersky/SE cells; along w the advantage of less weight, less space required.

Remember- dont be "penny-wise and pound foolish ( cheap up front but paying more in the end )
