What's the BEST battery for eBike?

[Just]

Hi All,

I have Cyclone's 1200W motor, which works from 48V battery. The continuous current is ~25A, peaks up to 50A.

I wanna to use 10Ah battery for this system.

What battery cells would you recommend? The cells should support at least up to 5C of continuous current.

Thank you!

Go for Headway and 50A bms

Yes, I actually used till now the 38120S 10Ah cells from Headway... They are cylindrical, take some place and a bit heavy...

So, now I'm seeking for some good cells to replace the Headway's ones....

If you don't mind burning down your house then HobbyKing Lipos should meet your demands. That is what I am going to use as my secondary battery.

Waw! LiPo are dangerous! I would avoid them.. Are there other options?

Nope I love Headway and I will stick to Headway.
Untill there is something better.........

I like the screw feature, I can rebuild the pack easily without soldering....

Cells in www.ev-power.eu are also with screws and they are rectangular (better than cylindrical ones). Not sure regarding their life cycles and internal resistance - they don't publish these vital parameters.
Why did you recommend this site?

What's the official site of the Headway batteries? I'm a bit confused regarding these batteries. There are many companies sell these cells? Is the Headway not a trademark? Is the company USA-based? China-based? Other?

Well I have bought small battery for my battery charger.
It looks much better then Chinese Ebay ones and the choices are big!
But the prices.......


Also if you look at Headway specs, Headway is much better for your money

Well I thought I should insert a few statistics on the GM LiFePO4 batteries. Ive done some calculations. Of all the LifePO4 batteries I sold so far.

Less then 2 percent Key switch failure.
Less then 1 percent Cell failure.
Less then 1 percent BMS failure.

Without getting into exact numbers the LfePO4 48V10AH battery is the number two seller on my website and the 36v12AH battery is number Six. So I have sold a lot of them. Also I have sold quite a few 48v20AH and 48v30AH batteries.

Statistically I think the GM batteries are hard to beat. Also with the large square screw top cells, if you ever did need to repair your battery is would be very easy.

Yes I had one earlier type GM battery.
But it died very quick (within a year).

Also I like to see the specs of the battery, I like to know what I am buying....
Maybe GM should share those information.

Personal I think Headway are hard to beat.
A lot of power for good value and quality....
