    Battery pack for full suspension bike

    Hey, Just wanted to show the burrito battery pack in a full suspension bike. This is the latest revision which is pretty secure. You can see me bounce the front end of the bike and the pack doesn't move much at all. A pretty good solution, I think, for those of you looking to electrify a...

    Electric Cycle Truck Cargo Bike

    Cycle trucks are a little unusual but I've been seeing more companies offer them lately so maybe they're making a comeback of sorts. They've been around forever. Anyway, my buddy Dale Saso has been building his own for years now. I had the honor of helping him to electrify his. I provided...

    My 36v LiFePo Burrito Pack

    There's been a lot of discussion about LiFePo4 cells for electric bicycles so I thought I'd chime in. I'm importing 2 amp chargers from BMS battery for use with Headway cells. The 10ah headway cells are rated for 5c continuous and 10c burst. That's 50 amps continuous and 100 amps peak...

    Do headway cells really need a BMS?

    Do headway cells really need a BMS? I'm thinking no. Here's why: 1. EXPERIENCE: I've used thundersky 100 ah batteries (which is LiFePo like the Headway) in my car for the past year without a bms and I haven't had a problem yet. Actually, i did replace one cell that was killed by a shunt...

    limit speed of 12 fet ecity controller?

    Hey, So i've installed a cute 128 and 12 fet controller on a trike which I'd like to sell. The problem is that it's way fast (18 mph) and if you take a turn that fast, you could get into trouble. So I'm wondering if anyone had an idea on how to limit the power on the controller or maybe...

    Can you go without a BMS if you're careful?

    So, I'm working on my car conversion. I'd like to use Headway cells 24s8p that JD's been using. The thing is that BMS circuits are expensive for that high a voltage and current. I'm wondering if I can go without the BMS if I'm careful? I can monitor the cells with a DMM or a monitor for RC...

    66v 80ah lipo pack for car conversion, why not?

    I'm thinking crazy now... I'm not an expert at rc lipo packs so I'd like to know how you would charge 66v 80 ah lipos. config is 3s16p (48 pcs) of the 6s1p zippy 22v 5ah. what would you need? 3 chargers at least but how would you connect them? can you string chargers together? How do those...

    drop in top speed due to cold?

    Hey everyone. I noticed a drop in top speed from around 33~34 mph to 32~33 mph. It doesn't accelerate as hard as well. Anyone notice this too? I have 1500 miles on a Pheonix racer with 56x15 ah (more like 53x12ah) milwaukees. It's started to get cold around here and I wonder if this is...

    My 54v/15ah Milwaukee pack for Revive

    For the longest time I was going to get the Eonyx pack from electricrider.com but I decided to stick with the milwaukee packs. Mostly because of cost ($1600 for the pack I wanted) and partly because their 20 ah pack is huge! It would be tough to figure a way to mount it to my Giant Revive...

    does internal resistance cause imbalance?

    So I've got my pheonix racer going with my 2s3p milwaukee v28 packs. after a short ride, I'm getting an imbalance from packs connected in series. One pack has 3 bars showing and the other pack (which is connected in series to it) is showing only one bar. The only thing I can think of is that...

    what is acceptable difference in voltage between packs?

    Good afternoon fellow collective members, i'm using my milwaukee packs and after 1500 miles or so, they are showing their age. part of the problem, i think, is that i didn't buy them all at the same time (4 packs bought 11/06, 2 packs bought 3/07, 2 packs bought 5/07). i've tried to even out...

    I'm procrastinating on some work I have to get done today... I was thinking that a with such a wide range of performance capabilities, it might be somewhat useful to classify ebikes. Class A - peddal assist Class B - power on demand top speed below 20 mph Class C - power on demand top speed...

    rode in rain yesterday-- no problems

    Just thought I'd say my folder with 406 and v28 batteries had no problems in the light rain we had yesterday. I had my $5 rain pancho on and except for my lower arms and legs, I remained dry. So far, i really haven't needed a 2nd car. The bike has worked out great. We'll see what happens...

    What is most important consideration for a ebike build?

    It's an interesting topic for debate, I think. When building a bike, what is the most important consideration? 1. the BIKE 2. the BATTERIES 3. the MOTOR 4. the CONTROLLER I'm going to go on the record first by saying it's the batteries. The size and weight of the batteries might limit your...

    Picture of my 2s3p milwaukee battery cable

    I kind of have talked about it already over several threads but i think this deserves its own thread. Here's a picture of my 2s3p cable. It's for the milwaukee electric v28 battery. Each battery is rated for 28v and 3 ah which, when multiplied by 6, is approximately 500 watt hours. This is...

    New folding ebike! (isn't it pretty!)

    Hey fellow ebike collective members. I put this together last weekend. It's my new ride. Dare I say it's the cleanest and most stealthy install ever! I'm using ebike instead of driving so I though a folder would be convenient for when my wife picks me up at work of if i'm able to hitch a...

    waterproofing your ride

    I guess this might be a better question for xyster but I was wondering if anyone has experience riding in the rain. I've got the go-hub and I'm using my ebike in lieu of a 2nd car. It's going to start raining here in a few months and I'm wondering if there are things I can do to get ready for...
