    It solved my problem. I also uploaded the .xml I used in my post from Apr 12, 2023

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    I have the 850C. I scrolled through the display menu but didn't figure it out. Otherwise this thing is ready for the owner. I set the light to go on automatically and turned off the sport mode option. I rode it in the dark and the light turned on and seemed to work as before.

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    O.K. Don't know what I fixed but I copied some data from KB-79's xml and the error is gone! Now all I need to figure out is the speed settings. Edit: I think I figured out the speed. The only thing I can't seem to do is get the default assist to start on 0. I flashed it and read it and it...

    Just installed 1.3.1 and have an error 05H.

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Thanks. I did read it but assumed since I just bought this this year, I should look up the latest data. Right now the bike is almost unsafe to ride.

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    I just installed a BBS02B for my neighbor. Biggest issue is the PAS overriding the throttle. My personal bike, which was done some years ago with a Luna kit, doesn't do this. You can PAS and add throttle if needed. The throttle is unaffected by pedaling. I usually have PAS off. On this new...

    Luna "Tiny" Sinewave Controller with BBSHD

    PS: I just installed my original 2013 GNG controller and the bike is up and running. So there is no issue with the bike.

    Luna "Tiny" Sinewave Controller with BBSHD

    I have a GNG motor I'm trying to get this controller to work on. I recently had my 35A GNG one fail. I used the same picture above to wire it up. I have a hall / phase combination that can get it around but it's not smooth. The motor will not RPM. I can put it in a tall gear and the low end...

    Exploring options on electric car build

    They make plastic coated copper tubing for underground use. I am assuming the price for 1/2" tubing is cheaper than 1/2" stranded wire. I seem to remember from school, many decades ago, current traveling on the surface of the conductor. I have not researched it much since. I figured I...

    Exploring options on electric car build

    I got the bug to build a fast electric car. I have put out the word to my local used car dealers to keep an eye out for a wrecked Tesla. I’m open to other motor options. I know the Tesla motor has the power. The chassis will likely be a Factory Five 818C. This would be a cheap, light easily...

    Tesla-Powered Kit Car Runs 9-Second Quarter Mile + M3 PMAC

    I have been tossing around the idea of building this very car. I have enjoyed my ebike so much I have a hankering to get an electric car. I have had a ludicrous desire for some silent thunder. I figure with the recent weather in Texas, there may be a flood of cheap Teslas on the market...

    BMS limiting my charge to 54V

    I'm back. I have been using the pack despite the voltage not acting right. I have been charging it to 52V through the BMS and topping it off through the output port to 54V @ 1 amp. I babysat the battery and verified that it will stop charging on its own. I have been doing this only for long...

    BMS limiting my charge to 54V

    The pack is 13S 5P. It started life as an eZee Flat battery. I swapped out the (3 year old) cells with new better cells. My current charger is from Luna and is 48V with display. It shows 54.6V when not hooked up to a battery. Currently the battery is installed in the bike and requires a...

    BMS limiting my charge to 54V

    I don't think I can measure each cell, the battery is welded together now. I had the battery opened up a while ago to fix a bad solder joint on a balance wire. The cell groups measured all the same then. The battery has been together since November 16. Assuming the BMS is doing its job, if...

    BMS limiting my charge to 54V

    I replaced my old 22P cells with 35E cells. Lately it seems I can only get the battery to take 52V (48V battery + 48V charger). I tried different chargers including a 52V charger. Today I charged it again and like before, 51.9V. If I turn off the charger and start over it charges...

    Swapping old 18650 cells with new ones

    I assume it is balanced. It has a BMS, the original one from the pack. When I first assembled the pack it would not charge. I looked inside and the balance wire plug had come loose. After that it has acted just like before. I will say it takes 5 hours to charge. With the 22P cells it was...

    Swapping old 18650 cells with new ones

    After first building the pack I took it out but only got 8 miles out of it. This was a cold day and though the power felt great, it cut out early. It recovered well and I was able to nurse it along as much as I wanted. It was cold and I was not dressed well. I was concerned that I could have...

    GNG Ultralight RC Mid Drive with Bluetooth control

    Me not being a fan of PAS I wonder how quickly the PAS stops helping once you stop pedaling. Also if it has a brake cut off option. The weight claim: 1.55KG MID DRIVE KIT UNIT (HIGH SPEED MOTOR, BOTTOM BRACKET, ESC CONTROLLER, PAS SENSOR, bluetooth connectivity) Not sure if it is a good...

    LightningRods mid drive kit

    My bike is based on a bone stock GNG belt drive from 2013. 48V 10Ah battery. It has been updated with your wide belt and 219 chain secondary. I think the stock controller is 20A max? I guess my point is the power I have is all I need to climb steep hills with my help. Many of the hills I...

    LightningRods mid drive kit

    If I may add my experience to the discussion… My bike has been fabulous since going to 35 to 1. Top speed is about 25 MPH depending how much I want to help. My bike is not built for top speed. My bike really shines when hill climbing. I have a fellow ebiker that I helped put a BBSHD on...

    Difference between reduction kit and regular

    When I decided to build an ebike, mid drive was the only option. My bike is for the woods and trails. I wanted hill climbing power plain and simple. After getting a GNG I started to notice the cadence was a little off. For me to keep up with the motor I had to pedal too fast. Changing gears...

    Difference between reduction kit and regular

    "Regular" is a bit vague. I have experience with BBSHD, GNG Gen2, and GNG belt reduction. All these systems have reduction of some type. BBSHD has a fixed reduction I believe is 21 to 1. On this you have no way to change it. Very quiet, arguably silent. GNG Gen2 has a planetary reduction...

    I helped with a BBSHD that had this problem. Changed the throttle and it was fixed.

    For the future Tangent drive? Bulk metallic glass..

    OTC: LQMT I watched this stock back in 2002 when it was an IPO. This looks like what your post is describing. I know they made golf clubs and cell phone parts. In the end it was costly and very limited in production ease. It would seem the material needed to be cooled uniformly and thus...

    Swapping old 18650 cells with new ones

    I bought some Samsung 35-E cells from Tumich. I started with some nickel strip from the internet but I didn't buy enough. To save time I bought some nickel shim stock from MSC and cut my own battery tabs. My friend Doug built a spot welder using a transformer from a microwave. A relay left...
