The software license comes with the disc. Here is a link to the West Mountain Radio site where there is a comparison of the different versions: http://www.westmountainradio.com/content.php?page=cba-compare. Looks like the main differences are that IV has a lower minimum discharge rate and some chang...

Hi. I'm looking to sell my Crystalyte 3540 ebike kit. Comes with everything shown. 40 amp sensorless controller. Everything is in very good condition. I had this built onto a mountain bike, but never really rode it much. I doubt that the kit has even 50 miles on it. Location is in San Antonio, Texas...

sounds like a scam.

I'm reviving this old thread with a good story about Ping battery storage. I hadn't rode my e-bikes for about three years since I moved closer to work. The bikes have been sitting in a shed in the hot Texas sun without ever being charged. Well now I'm selling my house, so had to get the bikes out of...

I have no idea what the gas price is in Central Texas. I started riding my bike (regular bike, not my ebike) to work most days. I filled my truck a month ago and it is still sitting near full. It could go to $10 a gallon for all I care. In the meantime, I've dropped 10 lbs and am in the best shape I...

My trusty old Ping battery from 2009 is still going strong after all these years. Not made in USA though.

Oh my gosh, that thing is hideous!

I have a Ping battery that I have stored for over a year without charging or disconnecting the BMS. It held its charge just fine. I wouldn't worry about it if it's just three months.

I want to add a plug for the Ping battery. I have a 48v 20ah Ping that I bought in 2009. It saw a lot of use the first couple of years with maybe two 30-mile round trip commutes per week. The past 4 years it has only been used a couple times per year and sits for over six months at a time in my shed...

My old Raleigh Technium mountain bike had those. It's supposed to give you more power on the downstrokes. I thought it worked well enough. I didn't really notice it while riding.

How To Make $1 Million

Step 1: Start with $2 million

Step 2: Open an ebike shop.

That discharge profile looks pretty flat for lipo cells. Could it be some other chemistry?

It's hard to tell what the range is now. My round trip commute is about 10 miles. A few months ago, I used it on three consecutive days without a recharge and it didn't cut out. So still has at least 30 mile range. I'm still amazed that sitting in a shed in San Antonio fully charged hasn't killed it...

In short, yes, you can do that. Parallel would give you twice the AH and discharge current. You'd probably want to put some diodes on the positive power output wires to prevent one pack discharging into the other when they are not at the exact same charge. You'd also want to separate them for chargi...

That's interesting, seeing as San Antonio is a bit warm in summer. What temp would you say it's stored at? And apparently stored full too. This is the first I've heard of a Ping going much more than 4 years. If the battery is big enough, and the controller modest, it may be you don't notice the ris...

I have a Ping battery going on 7 years old. I don't ride it that much anymore but every few months when I pull it out, it is still fully charged and still has plenty of range. So probably number of cycles is the determining factor in battery life. Shelf life doesn't seem to be an issue.

The fingers wrote:Regular $2.35, supreme $2.57 per gallon.

That's pretty pricey out there in Cali. On my way to work this morning in San Antonio, saw $1.37 for regular. That's just insane cheap. Pretty soon they'll be paying us to take it off their hands.

Cows also produce tons of CO2 and greenhouse gasses. When it comes to CO2 emissions, I do my part by trying to eat as many cows as possible, and choking stupid people. I dont know if it will change the world, but I feel good knowing that I am doing my part. Cows are effectively carbon neutral. Gras...

The newer Electra Straight 8 models come with front disc brake and a choice of 3-speed or 8-speed rear hub. It would work pretty good for a geared front hub motor. Since you already have your bike, maybe you could call Electra support number and ask how to buy one of the forks from the newer model. ...
