Headway 48v 10ah - EVcomponents.com

[Ypedal]

I finally got my hands on a Headway pack !

Why ? well, I sold my e-BMX ( with rear wheel e-bikekit.com 20" wheel in it and a crystalyte 36/72v 35 amp controller with a soldered shunt for 50 amps, Cycle Analyst, etc.. ) I run it currently with a PSI 10ah pack, since my PSI packs are my original order from last season, and i've been experimenting with them ( no BMS, 10C discharges on the RC bike, some cells have been sitting for months, i have some with broken studs i've been messing with.. ) I want to keep them until they die for scientific reasons

The BMX, well.. that i don't mind at all, i will build another one next summer.. love the BMX....

On oct 1st, I ordered via http://www.evcomponents.com :

On Oct 3rd i got my invoice, paid immediately..

- 48v 10ah Headway pack with BMS 349$
- Shipping 95 $
- Paypal + 2.5%
- Duties and Brokerage 29$
- + Exchange rate to canada
Total : 520 Canadian $

No charger !

I requested a tracking number on Oct 20, my customer getting anxious to ride his new to him e-BMX, yes, we have had snow already !!, i was then advised that the container had just landed and it would ship by end of the week.. . Had i known this i would have advised accordingly and avoided pissing off my customer.. doh.

Last night, Nov 2nd, FedEx left it on my doorstep ( they attempted on previous friday but i was at work and they required their duties and brokerage.. ). I had requested USPS on my order as the online calculator does not yet determine shipping to canada, but i arrived Fedex...... all in all.. that's fine by me.

These cells are as fresh as possible = bonus !

Box was in relatively good condition, no holes .. good.. ( I always take pictures of anything i get shipped, i work for a shipping company and nothing says proof like a picture )

You mean that this isn't a box review? We get to see what's inside? Man that is just toooo coool for me.

Hey, now we know the info many of us really wanted to know. How much does it cost by the time it hits your doorstep? We can count on Ypedal to do an exahustive scrutiny of the thing, but it does take more than overnight to do it, and it isn't the weekend.

[Ypedal]

Lmao.. sorry guys.. got sidetracked last night ( had to format neighbor's pc and reinstall XP... never fun..)

Back to the pack !

So, i anxiously opened the box, I was expecting exactly what was in the picture on EVC, ie:

[Ypedal]

To my VERY pleasant surprise !!!!

[Ypedal]

I like ! No cracks, but a shake reveals indication of something moving inside..

[Ypedal]

Headway molded into the box, nice touch.. + and - also there ( a colorfull sticker would be a nice added touch for those of us with less than 20/20 vision.. but i'm happy with the box ! this will save me a wad of time and efford.. A+ ! )

Voltage as delivered : 53.3v ! ( good ! )

It's like one of those Russian dolls. A box in a box.

I would have shook it too!

Now open the black one!!

[Ypedal]

Yes Sir !! Under the hood we go !

Simple 4 screw, pop the top.

Initial Observations,

- BMS is loosely held on the pack with tape
- Pack is not secured to the black box and loosely moves in there
- Broken red plastic tab on bottom left corner

All in all, not too bad, easy fix, Tipped the box sideways and the pack came right out, i see on the bottom of the black box some glue residue and melted red plastic in it, so an attempt was made to stick the pack to the box, however not good enough.

A quick check of the Positive+ and Negative- wires from the BMS to the pack reveals that the + wire is not tight, the cable spins around easily, the negative wire is solidly attached, the bus bars seem ok, sense/ballance wires connected with copper rings instead of being soldered to tabs is one thing i like..

Imo, The pack wires need to be secured to the pack itself, and the terminals need to be coated in either hot-glue or equivalent to prevent vibration loosening, hollow spaces inside the box need to be occupied with foam or other matarial to prevent movement of any sorts, WHEN not IF i crash, i want this thing to stay together..


More later tonight after the day job...

[northernmike]

Thanks for this stuff! Keep it coming!

- Pack is not secured to the black box and loosely moves in there
2- Broken red plastic tab on bottom left corner

, but a shake reveals indication of something moving inside..

1 They tried with hot-glue but it isn't glue at all just melted plastic and couldn't hold a dead fly in place.
2 Those are the cause of the rattling sound you hear

Take that flat packing material and roll it up and you could stick that on the end on both sides of the bms. Another cut down piece could fit on the other end.


RE: reinstalling XP - next time just install Ubuntu.

[dogman]

By now they know they better not send Ypedal any duct tape wrapped batteries.

But i'm impressed, why the heck can't ping get some plastic boxes made for his packs?

[Doctorbass]

what is the size of that box?

I would be curious to see the Wh per liter resulting of that battery

485Wh 100%dod for what volume?
