    S12SN 72V LCD3 P1 Parameter as Speed Governor Tested

    A little background on my setup. I was using LCD3 with a 48v controller and 1500 watt front wheel hub motor. Yes it's stupid crazy, chopped off what was left of the broken dropouts and installed a make shift steel reinforced one using welded flat bars and tubing to bolt on to the suspension...

    help with BMS S12SN controller

    The ignition is on the lcd connection. If you have or are going to get the lcd you can place a switch inline with the v+ to act as ignition (red wire). If you don't have lcd and your motor is compatible with the standard settings of the controller (assuming the controller is preloaded with...

    Regen braking with S12SN controller

    I won't be able to test that out right away. Possibly in spring time.

    Regen braking with S12SN controller

    I don't recall the original settings exactly, but I remember not changing the number of magnet poles (P1) which was 46 in my case and C2 phase was set to 0 for ordinary which was also not changed from my recollection. Hopefully your motor is the same configuration. The package did not come with...

    ADEN-Sports, Power Kit Race (Review+Pictures)

    Very interesting! Is rolling resistance a concern? Water ingress? The width of gear has potential for flying debris to lodge in from other riders. Still very cool lightweight setup.

    Hook up as shown on your diagrams, place a switch between 1 and 2 to act as power switch. Test for 5v on the pas cable.

    s12s slcd3 problem

    That's too bad, will be losing a bit of range only charging to 38v. Still odd the lcd dims that much, unless it was programmed for two power settings but thinks you are 48v pack from its quick check. But since you can now run at 38, keep running it down to cut off voltage, hopefully it will...

    More Volts for speed battery mounting help

    How is the old pack charged? Is there a separate connection for charging or are 2 of the 4 prongs meant to charge the pack? Will need to know how the 4 prong works to properly wire your new pack. New pack 3 prong looks like its for charging... IE on board charger in the pack, is there any other...

    s12s slcd3 problem

    It is very possible. Though you can test the dim LCD problem by giving the LCD the direct 36v power source and check if it is lit up proper without connecting to controller. Another thing to try is to not plug in speed sensor, something is up with that (proper sensor should be set up to ground...

    s12s slcd3 problem

    Why is your P2 speed sensor pulse set to 6? You have 6 magnets on the spokes with the Hall/Reed sensor? Set C5 = 10 for max current draw if you don't mind extra power. C4 = 0 for zero start up handle bars. C12 = 4 recommended for 30V cut off. Have you tried running no load to the cut off...

    Wheelchair with Handcycle

    1) PAS not required. 2) You don't need to use brake wire. However you should remove the blue loop, this is cruise loop and will turn on cruise when you hold a constant throttle. Without brake wire you will have to blip the throttle to turn cruise off or switch the loop with a momentary switch to...

    s12s slcd3 problem

    Good to hear its working now. Thought from your last post you already installed speed sensor and works good, but was still turning off. That's why I mentioned if speed sensor was good, then only other thing would be batteries.

    s12s slcd3 problem

    If you have good speed sensor, but turns completely off at loads then you may have bad cells in your pack. Buy a 5 dollar volt meter and check your cells. You may have been overcharging some of your cells, too if you don't have bms to prevent overcharging... 41 volt of the pack doesn't mean each...

    Hallomotor hubs on ebay, August 2015

    I purchased a complete kit from them with 48v 1500w front hub motor. Smooth startup and silent sinewave controller. Speed of the motor is as described. Controller and LCD3 combo limits the speed to 72kph max unloaded, loaded I reach 55 to 60kph on fairly level ground. Currently swapped to a...

    Regen braking with S12SN controller

    I recently purchased an s12sn with 72v lcd3. Took a look inside the controller and it contains fb4410z mosfets. It also has what it calls EABS braking with inputs for simple trigger or variable trigger (not tested). Perhaps this is what it calls regen, lcd3 parameters can adjust the motor brake...
