    Basics of a Lithium-ion Battery Charger

    imho Even if 2x pins are ajoined on the receiving socket, dont mirror that on the input, it will limit the safe use of the charger to just the one single battery.. **Double and triple check polarity ;) XLR connectors are fairly easy to solder but the larger sized male pins can be a bit of a...

    Anyone own a big game bike ?

    Plenty of powerful options within the regs, perhaps the wheel size of the mirider was a factor in its disappointment off road? Im more than happy with my conversion which was no harder than changing a tyre, bolting on a few bits and tidying up the wires. A great option on a comfortable donor...

    Yose support staff are not native english speakers and rely on translation s/w But do respond promptly with real help/advice ( time-zones taken into consideration) in my limited experience of a single quickly resolved issue. After checking the above ( plugs fully inserted, pas orientation..)...

    tranzx system shuts off? raleigh stow-e-way

    Google informs me just how proprietary your sys is after i looked up the s/w sys you referenced.. So a 'simple' controller swap isnt on the table.. And my basic understanding of generic systems may not be fully applicable. Yeah roadside diagnosis isnt ideal. But if i understand correctly. 1)...

    ?? Hang on a sec... not a qualified engineer here but i dabble (take things apart).. and in my very limited experience with uart/serial usb coms on state machines and soc pcb's systems, when supplied with logic level power they invariably boot up.. Is your usb cable supplying the 500ma 5v...

    Check the display for any model or id info for a google search including 'manual .pdf' to get help decoding the error state, Due to the 1 battery led only i would guess its a low voltage error without any other info, Check the battery voltage, and the connections in its cradle, some styles...

    Hoping to increase driver passing distance at night, I've glued front and rear reflectors to my wing mirrors.

    just a thought, but could you tac or glue a paintball to an oxford lollypop extremity? it may leave a reminder to keep away next time without the damage my initial thought (claw hammer) would inflict.. ;)

    tranzx system shuts off? raleigh stow-e-way

    Frustrating.. Any similarities between fail conditions?? does the bike cut out after X miles or when ridding up a particular hill? #1 eliminate the possibility of battery coms, check battery terminals for voltage levels. While most systems ive read and heard about will shut off the battery...

    tranzx system shuts off? raleigh stow-e-way

    There are loads of bikes out there and models change from year to year, a few pics of the bike, battery, sensors and handlebar display will clear up a lot. One common problem is battery cases/cradles warp a lil with time and perhaps a less than perfect fit and bumpy rd is dislodging the battery...

    tranzx system shuts off? raleigh stow-e-way

    Dont know your bike/system, but it sounds more 'bolt on' with a hub motor if the controller is housed in the battery base? Pics will help the ignorant like me.. Assuming the new battery and wheel motor are in fine condition and its oem control system issues giving you the headache.. the grin...

    Any experience with Estarli 28.8 Hybrid or Trapez?

    Woosh and wisper both contribute in here and sell bikes with quality parts and very good reps.

Custom built in battery formats, and 'smart' batteries that need...

    help on buying brake pads

    An angle grinder or even a dremil with a black cutting disk can cut both cable and sleeve cleanly with ease. a wrap of tape round cable helps, and a if you need to rescue a frayed cable end a hot burning torch can fry off wayward strands. (mapp/butate?) if using blunt cutting tools a thin awl...
