E-Bikekit.com 36v 10ah LiFePo4 Battery

[Russell]

The test results posted on the E-BikeKit website for their battery is pretty useless as it was performed at 0.2C. A 1C test would be far more appropriate because let's face it who runs their ebike at 2 AMPS

Frankly I think this battery is waaaaaaaaaay over-priced at $598 w/2A charger + shipping.

I'd have to agree with Russell. This battery is way overpriced. After a month of nearly total discharges two times per day four days a week (8X/week) the battery's ability to charge has changed. It used to take 5.5 hours charge, after running out of power completely due to a strong head wind, the battery now takes 6 hours to charge.

i gotta agree with jason on this. not everyone wants to buy a battery off ebay just to get it super cheap, no matter how poorly it is built.

he sells the battery as part of his kit so people get something of break there, and it motivates them to buy the battery as part of the whole kit when they see how much more the battery is by itself.

that is just what marketing stuff is all about, he's trying to get his customers to consolidate their buy into one order, from him.

his customers aren't people from the sphere, we are more like free vacuum cleaners for his excess inventory.

but he is really putting together something that works for the newbie from the first day, a complete kit they can put together and ride on with some confidence and reliability. he has done a number of little things that really add up . like truing up the chinese machine trued rims, and including the spoke wrench now too so people can maintain their wheels, and the torque arms so people don't end up ruining their brand new bike. educational videos and the talk back thingy. andersons for the phase wires so the connectors don't melt down. i think the 9FET controller is great value too, and the 9C motor just is so luxe compared to the other stuff and not so fat as the C'lyte.

this is stuff we all diddle with all day but the regular joe who wants to be a DIYer can quickly get freaked out by stuff they are not used to doing. like manual mechanical work and maintenance, and that is hard to get people through because they all clam up and say, 'i can't do it' so he is trying to cover all the small things that hang people up like that.

all imho, YMMV.

he isn't trying to sell to the low bid ebay crowd, and the pack has proven to be well built and proved out to full capacity in ypedal's testing, unlike the other ones, and he does stand behind the battery too, 100%, i know that for a fact.

This is a popular thread and we're grateful for the feedback. Russell, just to be clear..do you own or have you tested the E-BikeKit 36v10ah pack?

Regardless we would encourage using the popularity of this thread to suggest where people can buy alternative comparable batteries. The more options people have the better. If ES members have sources they want to post and also share their buying experiences it would be very helpful to our business and to our prospective and existing customers.

E-BikeKit has many satisfied customers and professional partners using this prismatic 10ah pack. We pride ourselves on being able to provide our customers with a high quality battery option that works very well with our kits to support legal USA standards. We offer excellent customer service, fast shipping, convenient ordering and a rock-solid warranty on all of our products including this battery. These are all important considerations when buying a battery. We also offer an alternative and more affordable 9ah cylindrical LiFePO4 battery for those interested.

As always we thank you for your feedback and suggestions and look forward to serving you soon.

No I have not tested your pack though I did follow Ypedal’s review. I'm glad you responded early on to Ypedal's test results and improved the connectors on the battery and while it may be a better quality battery than Golden Motor (I couldn’t say because I haven’t tested that one either) I don't believe it represents a good value at $534 +optional charger+shipping. Also while Ypedal’s test was good it did not contain graphical analysis of the battery pack at 0.5C, 1.0C and 2.0C so that we could have hard data. Just looking at the voltage sag during one of his videos however I would judge it average. When I went to your site and saw a battery performance chart I was pleasantly surprised however when I saw it was for 0.2C I felt either you didn’t know what you were doing or worse that you did know.

Since you asked for alternatives here are the batteries I would love to see in a back to back test. Unfortunately like most folks out there I can’t buy them all and test them out. Also based on this I would stick with my original statement that your battery is over-priced.

Actually I'm not comparing his battery to something won at auction on eBay, that would be unfair, I'm comparing the price to other batteries of the same capacity which are currently available. See my post above for some alternatives.

I agree that Jason is doing a great job as a seller, in fact I purchased one complete rear kit (on closeout) and another front motor with a controller (used at show). I sold the rear motor but like the front motor though it's in limbo right now waiting for the right bike. I even use one of the front controllers with my Bafang.

the headway from travis is the only comparable and travis is selling batteries cheaper than headway. i don't know how they can be making any money.

but if the charger and fees are included, i think there is not too much difference between the cost of what jason gets on top of the kit for the battery/charger and what travis is charging for their pack/charger/import fees, and shipping.

but most important to the customer is that they know they are getting all the pieces that will fit together, and people pay for that service for a reason.

my point was that jason is marketing to the rest of the world, not just a select group who spends their time doing this stuff for free. so he has to cover the cost of the stuff returned under his gaurantee too, since he is selling to people who expect they can send it back, for no reason except they get spooked when something goes a little wrong because the newbie goes dufus to the max. that part i can really sympathize with. i would not do it, i'm hardnosed that way.

Deleted. Thank you to all at ES.

 

[GoldenMotor]

The difference is, the connecting sockets and the mould.
ours have a logo embossed onto the battery.
the rest of the casing is the same.

oh also, the BMS and the cells are different.
looks nice.

Different=Better?

We've seen inside the e-bikeKit pack ..might need to start a new thread

 

[GoldenMotor]

No, not better. I didn't mean that. Our connector used to look like e-bike kits, exactly the same. However there was some legal issues on that type of socket, so we simply changed the sockets to legalize our batteries. Because chinese customs are all icky picky about our stuff, unless we give them cigarettes.

 

[chet]

Yes, the connector on e-bikekit is designed for 110V. It is the one part of my system that feels warm to touch after riding.

 

[maydaverave]

I am thinking about getting a e-bikekit with battery but am torn between the cylindrical 9 ah battery and the more expensive prismatic 10 ah battery. Is the cheaper cylindrical battery the same one that ypedal had all the problems with? Is one more amp hour and prismatic cells worth the extra hundred or so bucks. This is going to be my main transportation and I am willing to pay a little more for reliability. I want to get this right on the first try.

 

[Ypedal]

have both 10 and 9ah packs on the bench right now, expect more info by the end of the week.

The 9ah with 26650 cells is slightly smaller size wise than the 10ah with prismatic type, but both will power the ebk kit properly. I personally prefer the prismatic as far as durability goes but that's subjective right now.

Hang tight, more info on the way soon !

So you are also testing the e-bikekit 9ah battery, is it the same battery that you got as a surprise in the mail or is that a competitors and now you have the e-bikekits cylindrical battery pack? I don't mean to knit pick but I want to know for sure whats what. Thanks for the valuable information, I think it should help me put together a solid first ebike 8)

 

[Ypedal]

Well, i have 4 of these batteries on my desk right now..

1- original 10ah prismatic
2- other pack made with 26650 that ebk sent me to compare with the 10ah in this thread
3- 10ah prismatic with a dead BMS i plan to mod ( more on that later )
4- current 9ah cylindrical cell pack offered on ebk website.

no.4 looks very similar to no.2 but with different BMS and aparently better QC cells during assembly, i cleared the workbench last night and started charging them all up for a shootout test. :wink:

 

[torker]

Awesome, I was so excited I almost put in Ypedal as my username to login You are the man.. As you can tell I do this on a budget, catching all the sales, using sla.etc. So this time when I upped voltage I bought one battery. I now have three different brands on my bike. I'm really ready for 8 or 9 usable ah instead of 3 or 4.

Very cool. I have been waiting for a while for a complete kit with good performace and reliability to come out. Just waiting for one more pay check and your review then I will finaly have an ev

 

[Ypedal]

Ok.. tests are on the way, i spent all week cycling the packs ( this is a time consuming process !!! ) and also got sidetracked having to repair my mother's PC that was royally messed up..... but onward and upwards. Each pack got at least 4 cycles at 5 amps.

 

[Ypedal]

Update time :

1- Original 10ah prismatic, this pack has been thru the tests in this post, lent to the guy in Saint-John who ran it hard for a few weeks, left sitting for some time, lent again to another local while his eZee battery was replaced, sat some more and here it is over 1 year later.

2- Other pack made with 26650 that ebk sent me to compare with the 10ah in this thread, this pack was used by a friend for a few months with an EBK front wheel kit, removed the plastic end caps and wedged it into the trangle of the frame ( perfect fit, no brackets required . )

3- current 9ah cylindrical cell pack offered on ebk website. This one i received a few months ago and had not yet taken the time to put thru the mill, i took it apart for a visual inspection and it is constructed very similar to Number-2. However more care in assembly was taken, the spot welds look better, ballance leads routed with a bit more care, smallish BMS and generally well built all things considered.

4- 10ah prismatic with a dead BMS i plan to mod ( more on that later )..

My LBD setup ( Light Bulb Discharge )

 

[Ypedal]

During the week i was using one of my older style DrainBrain meters and found that it was odd that i was getting almost 12ah from the 10ah pack.. something was not right . Today i went to the garage and stripped my Giant bike of it's red Cycle Analyst i used in my earlier tests.. plugged them both inline of each other for comparison.

 

[Ypedal]

Results :

The 10 bulbs consume 300 + watts at this voltage ( 8+ amps ) . all tests were run until BMS lvc, room temps 20 celcius.

pack 1- Prismatic cell : Meter 1 = 9.844ah --- Meter 2 = 11.92ah

pack 2- other : Meter 1 = 4.441ah --- Meter 2 = 5.022ah

pack 3- current ebk round cell : meter 1 = 7.558ah --- Meter 2 = 9.184ah

So which is the true amp hour reading? Average out the difference? Glad to see that pack three has signifacantly better ah than pack 2 because I just ordered pack 3 the other day

 

[Ypedal]

Meter 1 is the one to go by, it is a more recent model with updated software. I should remove meter 2 figures really... :|

 

[maydaverave]

I got my e-bikekit today and installed it on a old bmx looking single speed small tube 26" frame. I went with the 9ah battery, so far so good. After I put a some more shallow cycles on it I will check the range. I have 1.5" tires at 60 psi and I am hoping for 15 miles but only time will tell.
