Super Large Waterproof Electric Bike Controller Case - Durable E-Scooter & E-Bike Conversion Box for Motor Protection | Perfect for DIY E-Bike Upgrades & Outdoor Riding Accessories

Little too small for 36 vold ebike battery. My bad.Great productI wasn't happy with the little bag with velcro straps to hold my controller on my ebike. Purchased this to put my controller in and it was a great fit. Was able to get the controller and much of the loose wires to fit inside the case. Really cleans up the look.Fits my average size generic hall controller. What the kit should have come with is a grommet for the cables opening. This box provides better protection than the giveaway nylon bag the electic bike wheel kit came with.At the end I could not use it since the included loops that screw to the bottom around the bike tube are too small and my tube is larger in diameter.Could be better it does not have any mounting holes on the inside or anyway to fasten a motor controller from bouncing around when in motion i had to use a drill to make mounting holes for my controller also doesnt look very waterproof or water resistant but can easily add a rubber seal to help with making it more water resistant ive also added a rubber grommet where wires come out.Great box for my controller on my new Ebike build 3 wheel schwinn meridian w/48v1000w99ah system .I wanted to build a 13S 5 p battery pack. So I maxed out the space. I had to cut some of the plastic ridges down to fit my bms. It's still a little too tight but it works. I think it would have been better to build a smaller 13s x 4p pack instead. F.y.i. I forgot to lock it to the bike and it flew off the bike after hitting some bumpy terrain. My batteries seem fine so I think it protected them well. Also, it came with an LED battery indicator and switch I didn't hook up because i fought with space so much plus there are no instructions on how to exactly wire it up and I didn't feel like figuring it out.
