  1. Hi, in Milwaukee. I have a KS18XL for sale, gently used, never dropped. Fast charger, in addition to regular charger. 2000w 84v 1554 batt. Willing to ship! Update: sold! Thanks
  2. The controller says it is 56-90v so it should work fine, yes? You are recommending I use the BMS on the ks, and just add a fuse? I would then only need to know what battery lines to tap, to run power to my controller. I've been looking for videos, pictures or advice on this from anyone who has done it previously. I can't proceed until I know I'm doing it the right way. I'm a welder and sculptor, with only a small amount of electrical knowledge. I can hook things up right, but I need guidance to know which things to hook up.
  3. I don't understand... How would I wire in the batteries and charger port without a BMS? Is there a guide for this somewhere?
  4. Yup, I'm connecting the motor and battery to be controlled by a KT 50a 56v-90v 3000 watt controller, thru a marine blade fuze box to make sure it doesn't blow, and I'm just using a BMS to monitor the battery balance and charging. I have it mostly wired up and am just waiting to finish welding the ebike frame before I install it and test it. I think I did a very careful job researching everything, so the compatibilities will work? I am actually running a question by kingsong themselves right now, which is about my last uncertainty of the battery wiring system, to make sure I atta
  5. Just a quick addendum to add that I did some research into bms and I'm going to try this one: https://www.amazon.com/3Series-Protection-Li-ion-Battery-Balance/dp/B075MH52JG/ref=trb_chk_auth?dchild=1&keywords=2s+60a+bms+12v&qid=1622896662&sr=8-2-spons&psc=1&smid=A2KRDQ1AI5Y5G6&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExMTlLSDNEWjdISlI4JmVuY3J5cHRlZElkPUEwMzUxNTg4MVMyNUIyOFVFNlk5NCZlbmNyeXB0ZWRBZElkPUEwMDY2MzA4MkE2RkswQ0JBMk5KRyZ3aWRnZXROYW1lPXNwX3Bob25lX3NlYXJjaF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl&openid.assoc_handle=anywhere_us&openid.cl
  6. I'm doing this now. I originally modified my ks18xl into a one wheel vespa, inspired by the Bel Y Bel one. But the issue was that the KS18xl is so powerful that it was actually over cornering... So I decided to use the motor and battery and drive them with a 90v 3000w KT controller. Everything is going great except for one thing: I'm not entirely sure what to do about battery balancing, and could use some advice. I removed the king song controller from the case, and have just the batteries and motor in it currently. But part of the controll
  7. Thanks, that is kind of what I've been looking at. I found one that does 4000w at 84v but I was afraid that might overwork the motor, since it's not rated at 4000 constant output. I am probably going to go with a 3000w also. Glad to know I'm not the first guinea pig
  8. I'm working on a mod project and I am considering rewiring the motor of the ks18xl to be controlled by a throttle, but I'm not familiar with this kind of thing. Is there a way to connect a throttle into the motor directly or would I have to do it thru a hub motor controller like on electric scooters (essentially what I'm making) If so... Would I have to find a controller that works at 84volt? I imagine I'd have to connect the motor and the batteries to the new controller, and the throttle to the new controller also. Does anyone know of a controller that can do that? Most seem
  9. I made one of these? It's based off the Bel y Bel Z One custom monowheel, but with slightly different era Vespa panels. And a different EUC inside it. Mine has a KS18xl. It's Vespa Vbb panels kitbashed onto a fibreglass and steel frame. I felt it corners too aggressively, so I'm currently turning it into a reverse tripod.
