Ypedal, have you used this crimper:

It's the one I have and I can't imagine using anything else. It's got a slick ratcheting system that makes it impossible to muck up the crimp and has some serious leverage to achieve the correct compression force.

Next batch of Andersons i order i'm getting one, used to only be the APP unit ie: 100$+ but now there is the 40$ knockoff that i've noticed.. I got the hang of the cheap unit by now ( after 100's and 100's of them.. ) but the fancy tool look cool as hell ! :wink:

Don't even bother waiting. Order it straight away. It's very well made and holds the contacts in position. You just slot the contact in place and if you're wire is already stripped you just slide it in and ratchet down the tool. It doesn't release until the correct force has been applied. It can be done in a matter of seconds and it's quite hard to screw up.

I've only used the 45A contacts but I assume the 15 and 30a are just as easy if not easier.

Cheers!
 
Went digging thru my parts stash and found an Axiom rear rack.. gives a rough idea what to expect for scale, one would have to get a bit creative to mount this thing but this is fairly easy to do.. a few spacers and zip ties. or hose clamps.. better yet.. nuts and bolts.. Could also be side mounted like a pannier style..

So far i have aprox 30 cycles on the pack, most are 50% DOD, 3 full cycles to BMS cutoff.. one of wich i had the charger plugged in while i was discharging :oops: no harm however.

This pack being No.1 down the pipe, has some minor things that can easily be done to improve it, it would have been suitable out of the box, but why settle for less .. Jason has been reading this review and we have gone over many of the things i've pointed out . I"m assured that future batches will be improved and the product will evolve. It's not easy dealing with ebike factories, getting them to do certain things, as simple as they may seem .. I've ordered all sorts of stuff from China and other ebike vendors in the past ( see my projects page for an idea of a few things i've had to deal with ) getting a kit up to snuff is not an easy task ! :wink: and i have to give Jason credit.. he's one stubborn and determined sob to put up with all my nit picking so hats off to him for that ! 8)

Now this leaves me to the next step, a test run on the road ! :D

Slight problem however is that i'm stuck in the middle of winter so this will have to be a winter wonderland test.. more on that tomorrow !!

Upright view of the pack, with handle .
 
Come on stop blaming winter, snow and hardpack definitely make it the absolute most fun time of the year to get around using a bike, eat up your porridge so you can become a big hairy ebike dude! But seriously I'd "review" the hell out of it anyways, looks pretty sweet, like a perfect match for my P2-A w/20A controller. Especially compared to lead.

A few thoughts on the batt: It's nice that alu case would transfer heat well but that works both ways, and some batts choke pushing teh amps when it gets cold out, so how about freezing it to -30 and checking if it can even make that fuse pop, or something? Also, since it fits on the rack I wonder about carrying of passengers on it, seems like it may bend the holder plate thing and make the battery hard to remove/non-removable... Or would it? Also I see how it slides on but it's unclear to me how it clips onto the holder plate thing, I'm assuming something plastic has to do with it, meaning it'll conveniently snap off when it gets cold out? *chin scratch* In any case looks like it could use a piece of plywood to take the edge off the edges.
 
1st Ride of 2009 !!!!! :mrgreen:

However, a short one.. :oops: .. It's -30 celcius ( -22f ) out here today, but i can see some pavement !!!!! so .. well.. that's good enough for me !

Electrical taped a Cycle Analyst to my handlebars, pumped up both tires to 40 psi from like 10 ( yeah.. it's been that long :shock: ) , toque, gloves, winter coat, boots, tinsulate neck guard, backpack with battery pack.. and away i went. :D

From a full charge, 41v, slowly rolled down my iced driveway, all the time i've been spending on my unicycle paid off :eek: .. spun the front wheel a few feet :twisted:

Voltage dropped to 36v at 20 amps off the line, and i managed to burn up 1 ah in about 5 minutes. voltage settles flat at 34.4v ( 12 cells means 2.8v per cell ).

At this point i contemplated getting my ski-doo suit and full face helmet to try and stay warm ( i could pedal.. but Ypedal when you are testing batteries !! Bading .. tssss )

Pointed for home base while i could still feel my legs.. at least a little bit... :lol:

Pack was warm, not hot, BMS did not cut out at any point, i went up and down my street with brakes on both ways, 20 amps for 10 seconds + without incident.. cool.

I need to redo this road test when it's warmer.. more on that one later this week ! Hopefully.
