  • Waterproofing for BBSHD and BBS02

    How resistant is the kit to large amounts of rain?

    Well the controller is potted so that is water resistant, and there is a gasket that prevents moisture from getting in to the motor itself where the controller connects with the motor, and all of the wiring is water resistant as well.

    But there are things that you can do to improve the system.

    I would put a bit of silicone around the gasket (especially where the wiring exits the controller), and put a dab of permatex dielectric grease on each of the connectors before inserting them together in order to make them further waterproofed https://www.walmart.com/ip/Permatex-...Tube/194976983 (note: use proper dielectric grease, not battery terminal protection grease from auto parts stores)
    Note: you can also put this around the gasket on the controller if you want a more temporary seal instead of silicone or liquid tape.

    Recommended to use a dab of dielectric grease on every connection and cable that there is, including the battery connections. You don't need to overdo it, just use a small amount.








    Depending on what you buy some batteries and displays have USB ports, or other places where water might seep in, for example the places where the battery housing comes together. The USB ports are an obvious weak point so you want those protected at a minimum. No battery is perfectly waterproof so if you are using it in extreme wet conditions you may want to take extra steps such as wrapping pack in a plastic bag.

    You could build custom covers for battery/display or you could use silicone along the edges of the housing. For things that are meant to be permanently sealed and not needing to be opened for possible maintenance in the future (i.e. everything but the battery) you can use "Liquid Tape" on the edges of the housing. Also use liquid tape on the wiring exiting the selector switch on the display, if your display is such that the switch is separate from the display. The batteries in particular should be attended to with thoughtful inspection, if it is a hardcase pack, especially the contacts where cradle meets battery case. You can always cover the pack with a plastic bag as well if it is truly pouring down for days on end. (Note saltwater is much more corrosive and should be avoided and/or extra precautionary steps taken to protect pack)

    Then you have the throttle and E brakes, the E brakes are pretty durable and should not pose a problem however the throttle is a bit of a weak point because due to the nature of a throttles design it has to be somewhat open and exposed. You can stuff some grease down into it which should help and silicone along the seams that should also help. I would still recommend you have a spare throttle though. Worst-case scenario you just use the pedal assist as a backup until you get replacement throttle wired in.

    Then you have the gearsensor cable, and any/all other unused component cable connectors. These should be protected. More grease, cap them off, then tape them off. Take care to do this right and do not leave connectors exposed.

    You can also further protect the gaskets on the motor/controller housing with a thin bead of gasket compound. I would pay particular attention to the place where the wiring exits the controller
