    "Switch" ebike, battery with one bad cell

    Oh! I forgot to mention this: Would one of those ebike-system testers be of use? I've seen them listed at some sources for parts and kits. From EM3EV http://em3ev.com/store/index.php?route=product/product&product_id=87

    "Switch" ebike, battery with one bad cell

    A knee-jerk reaction would be to suggest looking at a programmable controller from Lyen once we accept the fact that it’ll be more expensive than you have paid for the whole bike. However, I'm sure there are salvaged and other replacement parts out there for less. One thing I do recommend is...

    "Switch" ebike, battery with one bad cell

    That's very good news. If it's a bad BMS, the pack won't charge properly through it and will go out of ballance again. The good news is that it might be easier to find a BMS for a S10 40volt pack. So, with which controller are you going to replace the existing possibly damaged unit?

    Programming the Bafang Middrive BBS01+BBS02

    Nice! Sounds like a good starting point for me as well. I'll give em a try when I get to programming.

    "Switch" ebike, battery with one bad cell

    I suppose you can separate that one cell and try to revive and charge it with your RC hobby chargers see if it can take and hold the voltage well. If so, perhaps the BMS is the problem. I can see where you made the deduction that they are Lithium Manganese or Lithium Cobalt because of the...

    "Switch" ebike, battery with one bad cell

    They look like LiFePO4 prismatic cells. The 4.1 resting voltage throws me. I would expect 3.2. From the photo it looks like BMS wire leads?

    That's an example of the true spirit of open source if I've ever seen one. Kudos to Kepler.

    Awesome build! It has me hungry for cake!

    BBS02 Cake -- FS mid-drive build, v2

    Yup, that's what I've been experiencing. On a flat my weight and gearing have me pegged around 30MPH. I'm going to experiment with lower gearing to see if I can reach 28-30 mph with a higher crank rpm so the motor is happier. Anyway 30 is honestly is fast enough for my nerves on the walmart...

    New Bafang Crank-Drives

    Awesome bike with some sweet upgrades. The FS suspension pivot design looks like it will give you no problems with fitting the Bafang to the bottom bracket. Since there was a flange connecting both the bottom bracket and suspension pivot on my bike, I had to use home-made machine bushing to...

    New Bafang Crank-Drives

    That is still a beautiful bike. Wow. I like the design which has the appearance of being built for the purpose with the focus on an electromotive drive.

    First Ride: Mongoose XR-Pro Bafang 8fun BBS-02

    Thanks. It's been great so far but I want to put it to an endurance test soon to see what it can do. Interesting! I'll give it a shot. Thanks for the link. I'll check it out. The pack which mounts near the steerer tube kinda looks like a motorcycle fuel tank! ;) The weight of the battery...

    Hm... I'll give 9 levels a try though I might switch back because my town is rather flat for the most part.

    Build of Bafang BBS02 from Greenbikekit

    Is 3 0f 9 about the same as 1 when using the 0-3 mode setting. I never have bothered to set it to 0-9 because I don't want that many button presses to go from low asssit to max assist. Stock: They still have 20 or so here in the states but I can't put the coin to it at this time. Christmas is...

    Build of Bafang BBS02 from Greenbikekit

    That seems to fit in with my observations. Just teasing 30MPH on a flat with the 11 tooth gear and a very strong torque with an enjoyable ride by keeping the gear somewhere in the middle of the 11-32 set on any of the controller settings (three stages in my case.) I might want to put those...

    Build of Bafang BBS02 from Greenbikekit

    Sweet trail rides you guys have! Just when I was getting all jealous that many bafangers out there have another hobbyist to share knowledge and good times, I find that I've convinced the fathers of two of the kids which school with my girls to electrify their bikes. One loves the idea of the...

    Build of Bafang BBS02 from Greenbikekit

    Wow, those are very interesting for the price. I'm flabergasted at how much cheaper and lighter they are. I might have to experiment with those in some future. The BBS02 does not mind 44.4V?
