    It's been a while since my last post. The bike is almost done. Just finishing off the cannons.










    And I had an offer from someone so I sold it. Now Im planning on building another and Im looking for recommendations on batteries. I used Headway 10Ah cells in my last bike.

    That's a very popular question. To which I reply, enough to cover the cost of completing this one and building another with a crappy exchange rate from US to AU to purchase the parts. Also some workshop upgrades to assist in building the next one. Honestly, not enough for the effort I've put in but at least I'll have enough to complete the next and better equipment. I purchased a plasma cutter and made the required changes to my CNC mill to fit it and get it working. But again, Im looking for information on what batteries you guys are using these day.

    I was drawing up my circuit for the next bike with a Kelly Controller. The Controller wants the circuit breakers and contactors fitted on the positive wire. The BMS unit breaks the circuit on the negative wire. Seems a bit of a wiring contradiction.

    "Ensure that the B- wiring is securely and properly connected before applying power. • The preferred connection of the system contactor or circuit breaker is in series with the B+line." What's the reasoning behind this as it doesnt apply to the BMS?

    Damn that thing looks sweet!

    I've used Zeva (Aus) and Orion (US).
    Would happily recommend either.

    Cant wait to see version 2!

    Im using the Thunderstruck BMS....
    at bottom of charge I have a delta of 0.022v between highest and lowest cells after 55 charge/discharge cycles.

    Version 2 will be very similar. But I'll be using Vee Rubber monster tires and have a battery with a 10c rating. Current battery is 60amps which is a little limiting. Just a question on BMS circuit breakers. Will breaking the circuit on the negavitive wire damage the controller? Kelly Controller manual state "Ensure that the B- wiring is securely and properly connected before applying power. • The preferred connection of the system contactor or circuit breaker is in series with the B+line." I do notice it says preferred. Inbuilt BMS / Battery pack units disconnect via the negative wire so Im assuming it wont cause a problem? I just dont wish to damage my new controller.
