    Atmega16 firmware dumping. Win EXE editing etc

    Ok, so not an e-bike question, but this is the only forum I know of, and have history on, and that I know there are people here with potential knowledge to answer. I will make this a long post, by giving the back story first, rather than dive in with my question. This is actually related to...

    Legacy Cytronex NiMh 12 pin wiring. Info thread and a story

    Just had the misfortune to have to look at a Cytronex bike , a kit built on a nice little Cannondale Motor labelled as 180W 36 volt front motor, geared Three magnets on RSH of motor and sensor on the crank Unknown controller looks 6 FET, stuck under th bottom bracket. two nice little switches...

    Trickle current for BMS balance charging

    Can someone confirm what I am thinking ...regarding charging LiPo with a BMS with a single cell balancing current of 168mA (+/- 20mA). BesTech HCX-D131 If I want to ensure a nice balancing charge, I'd set up a charger to charge at that sort of current, so if I set a charge current of say 125mA...

    Easy Cheap, sine wave replacement

    Long story short... Just trashed my 18 FET Lyen 4110 controller Connected to CA-DP V2 Is there an 18 FET , pretty much , plug and play 18 x 4110!Sine wave replacement? 24 s lipo, to about 140 amp peaks??

    New 'modern' Sine wave? controller to replace EB218?

    I killed my EB218 yesterday. This is on my first bike..from however many years ago. 16,000 plus miles 5304 26 inch wheels Lyen EB218 with R12 region mod. SO I need a new controller, that will be compatible with all my existing wiring..I don't use the bike much any more..it is now an...

    A2B Kuo / Edge controller voltage reg stage failure

    Any one any experience with a A2B Kup / Edge PAS folder bike? The controller in particular. More particular..the daughter board voltage regulator. A friend of a friend brought it in the other day. I have traced the problem that is killing the controllers..I think.. and I do have a second new...

    Fast4Ward Edge - A2B Kuo fault finding

    Also posted this question on Pedelecs.co.uk I have only managed to find two threads relating to this bike, both of which were dead ends. Looks like the Fast4ward Edge folder is almost identical to the A2B Kuo..but I can not be sure. The Edge has a handle bar display, but I can not see one...

    Big lead acid single cell capacities

    Just got hold of some lead acid single cell units from a scrapped aircraft tug. 36 of them...2 volt each XWBF17's OK,so they are old...2006. so they are unlikely to have full capacity ..but I wondered what their original capacity should be...

    BBS02 two power level question

    I have a friend who has a BBS02 on order. He has benign contact with our local driver and vehicle standard people. Now, they are happy that a bike if built; and 'designed' from scratch can have two power levels...as long as they are not rider accessible..so a handle bar switch is OUT. But he...

    BBS02 PAS....torque or rotation detection + Display question

    How does PAS work with the BBS02?system? Is it torque or just crank movement? Trying to work out how gear changing with the derailleur works. You need to change gear with pedals moving but under low load. But if the BBS02 system is running , because you are pedalling, it is going to potentially...

    BMS cell HVC and lipo life

    Being a latecomer to the BMS wsy of life, I have a quedtion I have not seen addressed before. All the BMSunits I see from BMSBattery have cell protection set at 2.66 low , and 4.22 high. So balancing is therefore only going to happen at these elevated voltages. We Lipo users all pretty much...

    Don't do technical jobs after a 12hr day with no food

    Lucky escape for my 12 FET Xlyte sensorless controller last night. When I saw what I had done last night, I just assumed I must have fried it, but out of a sense of futility I tested it and it is still alive. I had been up and around the farm since 0600, and done various jobs ; tractor...

    Artic silver 5 as heatsink paste for MOSFETS

    I have seen a few discussions about the use of AS5 on CPU's etc AS5 manufacturer say that it is not conductive, but should be kept away from tracks/ traces IC pins etc as it may be capacitive. Well without thinking I used it yesterday on the heatsink/ tape on the IGBT's (power output...

    8-80 volt out CC-CV board on e-bay

    Hi guys, just came across this on flea bay. Paired with a wall wart or similar Switched mode PSU, or any other dc voltage supply, to give a neat little charging solution. up to 80 volts out and up to 10 amps. Would need forced air cooling if run at high power levels. but might make a nice...
