    Slackinator all the way. Any updates? I think I have 15/76 but I have but I can't even use the Torkinator to full potential since BMS cuts out.

      I have been "slacking" lately. I did however purchase a slackinator, 64 tooth rear and a 11 and 13 tooth front as well as some chain lengths that should last me a while. Hoping this weekend i can get it all swapped and keep riding. I have to be honest, i love this ESR more than my 40 build i traded for it. Decently quick, damn near silent and still fun.

        I ride mine to/from work everyday.

        I would like to adjust gearing to get around my peak current draw issue since I can't find a GoPrammer to buy. Why are you going 11/13 when those are known to bind the chain instead of adjusting the rear gear? BTW correction is that I am running 15/72

            Ill be honest, my ESR came with an 11 tooth and it worked fine on the stock motor as well as my torkinator. I had been running 11/72 and i dislike how large the rear sprocket is so i went up to 13 in the front and dropped to 64 in the rear. Figured it should keep my speed or make it a tiny bit faster and take off some of the crazy acceleration lol. We shall see, worst case i will re-gear again.

            Probably going to breakdown the ESR in the next week or so and get it powder coated over the winter.

                Edit: I have it but will likely use it. Much better torque than silver case motor.

                  Any updates? Been riding my ESR for over a year now everyday to-from work. Been great and only really had to adjust the brakes and tighten up the motor bolts once.

                    Hey! No real updates, its cold here in NY so i have not been riding it much just keep it charged and check on it every now and then. I did not get time to tear it down and powder coat it. Really tempted to buy a new raw frame and swap everything over. We shall see.

                    I am also thinking i might take the plunge and go Lipo soon.

                      Ok cool. I'm still trying to find out a cheap Lipo option that isn't too sketch. The 36v hooverboard batteries kind of worry me.

                        Let me know if you find any good options! I have looked into building custom battery packs but with Zero experience i would not trust myself with the off chance of burning down my house or something lol.

                          I think if you have a proper cut-off voltage programmed into the controller, the riding risk goes down. Then you need to deal with charging. Which I think you should stay away from those chinese chargers and go with higher end system. But the drama of putting batteries into special bags for charging just sounds annoying (but safe)

                            So looking around the following cells looks interesting:
                            https://www.batteryspace.com/lifepo4...assed-dgr.aspx
                            https://www.batteryspace.com/a123-li...ec-listed.aspx

                            I sent an email asking BS if they can assemble a custom pack that would fit the dimensions.

                              Or perhaps 2x of something like these:
                              https://www.bioennopower.com/collect...-pvc-blf-1212w
                              Not sure if 40A 2sec burst is enough.

                              I know the 300mS 50A burst on the Dakota LiFePO4 is not enough and full throttle trips the protection circuit of the battery. The 20A constant supports Torkinator at 100% throttle if ramped slowly.

                              Looks like they also make a SLA drop in style @ 9Ah, strange the constant amp is 18 not 20.
                              https://www.bioennopower.com/collect...d-green-case-1

                              So could make a 18Ah scooter from 4x of those.

                              Really wish someone was already running the Bionno 12Ah batteries and could give feedback. Would be great if could also ditch the spacer since on the hoverboard the deck is already so much higher up.
