    What Bafang BBS displays have a pin lock function?

    I have just updated by display on my Mtb with a 500c. I like that it has a pin lock function (I.e. You need to put a pin in on power up). Id like to replace the c965 on my commuter with a display that has the szmd function. So does znyond know what other displays have the same function?

    Video of the Bafang BBS02 kit

    As part of the "Creating Multimedia Content" module for my degree, I have to produce a 2min to 5min video and I've chosen the Bafang BBS02 kit as a subject. I got a 100%/A+ grade for the first part of the assignment (storyboarding, script, copyright issues etc), so hopefully the actual video...

    Adding PAS to EM3EV controller

    Hi all - I've got an EM3EV 6 FET IRFB4110 controller, and I understand there are pads on the board available for a PAS connection/function. I have one of these in my bits drawer, so does anyone have any instructions on wiring up and enabling the PAS function on this controller? Thanks in advance.

    Battery in a back pack - connection to bike

    Hi I'm putting a Bafang BBS02 on a full suspension mtb and there is limited room in the frame for mounting the battery, so I was thinking of putting it in a back back. The lipo pack is 9 bricks of 5s lipo, in 15s3p config. The combined size is 18cmx13cmx10.5cm. I do have the option of...

    Hi all. I I'm prepraring my Cute 100 motor for use on a new Lyen sensored contoller and I've noticed that the motor side of the connector has the normal three thick phase wires going into it and SIX hall wires - the normal red and black power plus green, blue, yellow and white. However, at the...

    Bafang SWXB swapping internals over

    I have a 175rpm Bafang SWXB motor - if I could find a 200+rpm SWXB would it be simple enough to pop the side cover off and swap over the internals with the case still laced into the wheel?

    Tell me about ...... block time.

    I've done a search but haven't found this answered...... I have a Lyen mini monster controller and I understand the principle of block time - i.e. it allows the motor to draw a higher amount of amperage than the programmed phase limit for x number of seconds. This can help with take offs etc...

    Freewheel chainset

    Hey all. I'm about to convert my full suspension mtb using a Tongxin motor in mid drive config. One piece of the puzzle is a freewheel chainset - I really don't like the idea of my feet being "forced" around. So, where to get one from? 1: EcoSpeed chainset looks lush but do the supply them...

    Series connection question.

    I have a 9s10ah pack and a 2s8ah pack - can I series the two packs together? If so, does that mean I'd have an 11s8ah pack at the end of it?

    63v bulk charger - what are my options

    Ok - I currently have a 15s lipo brick contructed of four 6s 5ah bricks and two 3s 5ah bricks. To charge I split the pack into a 12s10ah config and charge to 49.9v with a current modded Meanwell NES-350-48 charger and charge the remaning 3s10ah brick with my iCharger 206b. What I'd like to do...

    Made a new battery box (well, adapted one really :-P)

    Another evolution. Before:- Wasn't quite happy with the battery solution or more specifically the carrying method. Yes it was light but it looked a bit ameteurish and I was concerned about the packs being upside down and stressing the cables and also about theft and susceptibility to...

    Another series/parallel question.

    I currently have a 12s2p 10ah pack built from four 6s 5ah zippy packs. I'm about to put the pack in an alloy enclosure and I'd like to be able to monitor the cell balance from outside the box (and balance with something like a battery medic). Would it be ok to parallel the balance leads all...

    Series lipo pack question

    I currently have a 12s2p 10ah pack (4x5000mah 6s packs) and was thinking of experimenting with 15s by adding a 3s2p 10ah pack in series (made of 2x5000mah 3s packs) What I was unsure of was the discharge on the packs - i.e. would the 3s2p pack empty first due to it being only 110wh as opposed...

    Lyen controller lower phase current

    Hi All I'm running a Lyen Mini Monster controller on my Tongxin build. I put a Turnigy watt meter on it yesterday and it peaks at 16 amps on 44.4v Lipo - that equated to a max watt draw of 728 watts. I need to get this down to 550 watts max as these motors are, shall we say, of a delicate...
