Some of you may remember a few months back : E-Bikekit.com

Since that time, I’ve been keeping in touch with Jason and his progress. A short wile ago I got an email asking my opinion on a battery pack.. One thing led to another and I received this last Friday !

[Ypedal]

Nicely packed in foam, no loosies no rattles.. NO DUCT TAPE !!!!!! ( except on the outside of the cardboard box.. .. This being the prototype i'm assured the shipment on the way will be boxed in nice new boxes.. hey.. i've been working for a shipping company for 12 years and i hate seeing sub-standard shipping practices )

Notice the metal plate on the back, once you secure this thing to a strong bike rack, the pack slides on and locks in with a key lock. Pretty slick...

It appears you were posted a block of polystyrene

I just looked at the site & found this photo amusing:


I agree with this in principle, however bikes are generally converted and don't have a dedicated slot/spot for packs. Thus it's not surprising that the lowest cost packaging option is taken by suppliers since customers have a variety of individual mounting requirements.

Solid, no cracks, no dents, the aluminum box is well built, fit and finish is good on this thing. I was aware of this thing being on the way for a while now, but chose not to say a word until i got it in my hands, I've had this happen to me in the past, big hype and great expectations.. then get a pile of crap in the end.. This is a nice refresing change..

ahaha, too quick on your edit.

the block has been split apart & the contents revealed.

Looks good. Prismatic cells inside, eh?

Yes, and no.. i have a serious gripe with the duct tape.. too fragile for batteries this size..

Jason started out with Golden Motor kits and Duct Tape covered batteries, this is absolutely a big step in the right direction.. There is also a new hub motor kit on the way as well, no longer GM, am waiting on details of that as well in a few weeks or so..

Took me a while to find it.. but next to the carry handle is the usual RCA charge port..

Handle is strong and sturdy.. so far so good..

[Ypedal]

Soooo. the obvious question.. WHAT'S INSIDE ???

[Ypedal]

At the other end is the BMS..

I have not come across this bms before, it's compact, surface mount components..

Closer view..

[Ypedal]

It's a tight fit, no wasted space !!!

It looks like the battery Golden Motor sells on their website.

ha.. that must be a recent addition to their site.. i had not seen that and i check it fairly often.... go figure

..

So how does it perform ?

Plugged in the 2 amp charger, sealed unit, no fan. Green light comes on.. Good.

Made myself an RCA to Anderson connector so i could install one of my Cycle Analyst meters on the charge side.. and topped it off. It was fully charged as it only took about 5 minutes for the charger light to go from Red to Green..

Cycled the pack half a dozen times at 4 amps.. checking for the usual sings of problems.. no loose wires.. no unusual heat.. all good..

Then went for a capacity test... ( sorry for the blurry pic.. hard to focus on an lcd screen )
