Alrighty.. test no.1 : Voltage of all cells range from 3.240v to 3.332v, majority are 3.331v
Each cell has a barcode sticker, numbered, not all in sequence, ie: 0005 to 0485 etc.. no dents, no dings, so far so good !! best looking cells i've had my hands on so far ! 8) sweeeeet.

Mmmm....new batteries....SCHWEEET!!!
Yup, that's the way to pack stuff.
My batteries arrived just yesterday too from China. But I was horrified to see the packaging job on mine.
Totally different the way they pack stuff there huh?

Ypedal,
They look soo nice. You gonna give use the skinny on performance and stuff in due time?
My guess they are from Yesa batteries.
Hope they work good for ya, and continue working well after 2,000 km's, some of us had our 48 volt batteries drop a few AH's after few months use, but balancing helped a little, maybe a good BMS might bring them back to the top.

I suffered one dead one, but not being too technical I'm not sure if it was something I did, so I paid for a replacement (from Cyclone).

You are Correct !
I tried buying them thru Lifebatt, minor issues with paypal fees and unwillingness to work things out like a proffesional outfit should, my money was sent back.. so..
I found a very helpful contact at PSI who was great to work with, prompt replies and the shipping was quick and easy. ( I had a few problems wiring the money, but my bank is run by idiots and this is none of PSI's fault. Once money was received, the cells shipped.. got them 3 business days later ! )
Now it's time to put these babies to the test !!!!

Not cheap.... after shipping, transfer fees, duties, brokerage, gst, bod dave and john's share...
aprox 40 $ per cell at my front door... including a one 72v BMS.. but no charger.
48 cells = 1900 $
This is enough cells to build 6 x 24v 10ah packs. 8)

NOT lifebatt... PSI !! :wink:
Edit to add : The Chaos is getting 3 x 24v packs, and the other 3 packs will either go on the Chopper, BMX, or one of my other projects in the works !!!!
The plan is to build the packs to be mountable to any bike in my collection , quick on , quick off.

Forgot to post these yesterday.. the cells were provided with copper tabs, nuts, washers, and black caps for the threaded ends.
Got my caliper out and the copper is 1mm thick ( 0.039" ) 8)

I plan to use Gary G's and Fechter's BMS with these cells, but PSI offered this BMS kit, each board monitors 4 cells in series, communicates with a " Display " board and has all sorts of nifty features in cluding a " Buzzer " alarm, i'm sure i'll put it to good use..

Ooooooooooooooohhhhhhhhhhh... more shiny parts... BLING! BLING!
(What can I say... I'm just a simple guy... things like these just turn me on.)
Next step, to build these babies in packs.
I may change my mind, yet again, but right now i'm looking at building these cells in 24v 10ah each. 8 Cells.
Gary built his packs using " G10 " fiberglass board :

Yeah.. i know.. but i have not seen the surface of my kitchen table in months, my house has turned into a horrible mess to the point i have forbiden myself from bolting these cells together until i clear a path and organize myself a bit.. ( should have that done tomorrow ! )
My timing is just about perfect, i happen to be on vacation for 2 weeks !
I have, however, weighed the cells from 2 of the 6 boxes, they are not all " exactly " the same weight, range from 361 grams to 367 grams, majority 362g. I don't yet know what impact that has, but will make note of them all.
