Nic's Kawasaki Ninja 250 EV conversion

[DRZ400]

I bought from HAC, good service. I paid about 1,250 for 11 modules...but I was an early buyer. Several of us are using the Leaf and Volt modules without BMS. If you do, you need to stay it the 4.1 to 3.7 volt range on charge and discharge. Basically you avoid the cliffs in the curve and give up a little capacity. On the plus side you will get more cycles from your cells. I have over 100 cycles on mine now...perfectly balanced. In comparison my 40ah CALB cells were all over the place, so I used a mini-bms with them. These are automotive grade premium cells. So tempting to buy a 08 on up Ninja...love the look!

PS: Don't know the state of your ICE motor but I got $750 for mine on Ebay. There's a sprint car class that runs them in Mi.

nic, phil,

did you do a pre balance with your leaf cells? I'm planning to:

- connect all in parallel, let them rest to same voltage
- setup pack and go straight to bulk charging, probably at exactly 4.1 per phil's suggestion.

does that make sense to you all?

[DRZ400]

Mine were all at the same voltage on arrival....3.85v. I bulk charged to 4.1 than used (2) single cell lipo chargers to bring them to 4.2 Some bottom balance....allot more effort though.

Cool thanks

Matt,

I just ordered my batteries, they ship tomorrow. I'll check them with a voltmeter but if they are balanced I'll let you know. Also, I don't plan on getting a BMS until I notice any irregularities charging or discharging. Saves about $360 too. :P
Next up is charger research, probably checking out Meanwell or if I really go crazy, get a delta Q quiq the 1,500 watt version and then I need to find a place to mount everything.

Does anyone have any tips on mounting the controller, contactor and the rest of the parts? I don't want to weld anything that I don't have to. Or buy a welder and learn to weld....

I put my SMP72400 controller, DCDC and contactor under the seat.

I put my SMP72400 controller, DCDC and contactor under the seat.

What DCDC to you use? I'm trying to figure that part out right now.

Nic, which do you plan to get?

Joe,
I picked up 11 Leaf modules.
I pick them up today because FedEx is terrible and can't seem to deliver them. Still no luck with a Charger algorithm for the Delta Q. Aaron said he used #164, but Delta Q won't program it for me unless I buy from them(for full price which is insane), and EVdrives won't program for Lithium. I tried to get in touch with Frodus, but he must be busy.

Rant over.

I am really excited to now figure out how to mount everything after I bench test. Last up is the charger and then I'm all set!

[Nicman]

I picked up a DC to DC converter from EV drives along with my Delta Q charger a few days back. I didn't realize that the charger uses the same attachment plug shape as most computer transformers. Not a big deal, but one more thing I have to buy.
Speaking of the Delta Q, I plugged it in to make sure it was working, and I put my volt meter across the ground and hot and was only reading 30v. Does the delta q sense voltage with the black and white wire?
I hope they programmed it right and I'm not willing to test it out on my $1,400 battery pack.
I haven't figured out where everything is going to be mounted, but I have everything except a some 2AWG wiring! Almost complete, just need to fabricate a battery bracket (easier said than done) and get some stuff that HAC didn't send. (They sent the wrong size terminal covers, and didn't send the right amount of copper busbars for my batteries.

I also can't find out what size key I need for my 50 tooth, 7/8 sprocket (50 pitch) to fit on to the shaft of my ME1003. Who sells just the key for the keyway? Is it even called a "key". Assuming it is, this is my first motorcycle and the first time I've dealt with sprockets.

Lots of questions for you experts out there!
Any help would (once again) be greatly appreciated!

Lowes or ACE hardware have an assortment of standard keys.
