MrKitty Correct then leave 1ah or 10%

If you start to feel it drastically slow down all of a sudden you should stop and recharge the low voltage cutoff in the speed control should stop you at that point but I would be wary about the settings in your speed control until you know you can trust it...

Johnneh Thanks for clearing things up for me. My new watt/volt meter arrived yesterday... I plan to hook it up today, It also measured amp hours so I'll know the exact percentage of my battery (if it reads that I used 1 ah, then I have 9 ah left in my pack so the pack is 90%)

MrKitty People that say to keep li ion battery's or any battery stored in cold are stupid idiots ( putting it nicely ) cold kills battery's all types !!!

Room temperature above 50f is the best at half charge for storage. I just charge them up to full then run for about half the time and it's good for about 3 months then do it again.

Never store a battery dead some of the cells can fall below voltage then those cells will fail especially dead and cold that's a guaranteed way to destroy your battery pack.

To maximize the life of your battery you should always charge from dead to full without stopping it if you can even though stopping it won't hurt it if you stop at the same place every time the battery will develop a memory.

People that say that Lithium Ion or Lithium Polymer batteries don't have a memory are also idiots... the truth is that lithium based batteries are less likely to develop a memory then nickel metal or lead acid.

On Lithium based batteries dead means when you start to notice a big drop in speed if you run them dead dead where you have zero power your doing damage...

That's about keep it simple and that pack will last years...

Johnneh I've been reading a lot of things online, but they all contradict each other..

I need know how often I should be charging my lithium battery. Should I charge it every time I come in from a ride? I saw online that it should only be charged at 10% to 20%... Is this correct?

Some sites say that lithium ion batterys should be stored in the cold... but others say they should be at room temperature...

Idk what I'm supposed to do..

MrKitty the MX650 is a pretty cool bike for Endless mods thanks for the videos!!!

a67676767 do you have the model number for the speed control your useing ???

Re: MX650 mods?

I uploaded a video of riding modded MX650's on a dirt track.

Johnneh I was hoping it was a switch, but the throttle does not work when the 2 wires are shorted. I've also noticed that I have to keep the throttle pegged for 2 seconds before releasing the brake, to get full power.

So it seems the soft start is still happening, its just that none of the power is going to the motor until I release the brake.....

MrKitty It might actually not be a brake switch it might actually be the soft on or off switch 🙂 the writing or words on the plugs doesn't mean anything it is a very rough translation from Chinese to English at most.

Johnneh Ok, so, my controller does not have the cruise control option. I've looked at all the connectors twice, but found no sign of a cruise control connector. To be honest, it's not too much of a big deal for me...

While I was looking for the cruise connector I decided to connect the brake wires to the controller and you'll never believe what I discovered... I can actually bypass the soft start. if I use the throttle while squeezing the brake, and then let go of the brake it will literally launch me off the bike!! Lol!!

I might do more testing tommorow... it's going to be like 24F tommorow, so I might wait until it gets warmer.

Re: MX650 mods?

Fantastic! (sorry, i have a hard time understanding schematics for some reason lol)

MrKitty it shows that power can go both ways

Johnneh Just realized something... I bought this volt/watt meter. But if I use the regenerative braking, will it ruin the meter, by having power going the the wrong way whenever I let off the throttle?

Johnneh That's a fantastic idea! I'll definitely give it a try tommorow. 😃

MrKitty Right on I would think that the two speed switch would be pretty cool if you have it you could wire it up so that you can have a legal switch speed one could be 19 miles per hour and under ( most cities have adopted Rideshare programs and the speed limit is 19 miles per hour on electric rideables) ( make sure to check with city laws on this ) then you could switch it to mode 2 and have all the power... for off road!

Johnneh Thanks for that info. I'll look at the controller tommorow. And I haven't been able to try out the bike because it decided to rain all day, but I plan to tommorow.

MrKitty How does it ride with the Freewheel temporarily zip tied to the spokes???

MrKitty "BRAKE SENSE"
16 purple = Not Connected
18 yellow = Not Connected
17 green SL = 5 volts
19 black = GND.
As written, green is a brake sense switch. Connecting 17 green to 19 black halts motor power.

CRUISE CONTROL
26 blue Q = 5 volts
27 black = GND
To engage, get up to speed (30 Watts when bench testing a warm
motor) and momentarily connect 26 & 27. Cancel cruise using one of three methods: one,
again momentarily connect the wires; two, rev the throttle; three, apply the brakes with brake switch conected.

SPEED LIMITER
30, grey, XS = 5 volts
31 black = GND.

Once connected, full throttle uses only 100 Watts or half of full power.

2 SPEED
32 yellow = 5 volts, slow speed
33 black = GND
34 blue = 5

Default wiring is “fastest”, so only connect these wires if you want to go slower. cruise is not affected.

Speed Limiter Watts. RPM
Slow ON. 40 5 1540
Med. ON. 62 5. 2210
Slow. OFF. 84 5. 2825
Fast. ON. 95 5. 3150
Med. OFF. 120 10 3900
Fast. OFF. 186 20 5829*

DISPLAY
13 yellow = Not Connected
14 red = 5 volts
15 black = GND
signal to an hour meter.

that should clear up most of your extra wire questions anyway..

the other random wires are for e locks and small voltage trickles to power little things like cell phone transponders and stuff so the speed control can be used in bike share application's...

And charging but you shouldn't use the onboard charger because you have li-ion with a BMS

Johnneh Ok never mind about the welding part.
I actually managed to lock the free wheel by zip tying the sprocket to the spokes... idk how smart this is... but there isnt too much torque going to the wheel anyway because of the soft start.

Also, my controller doesn't have a cruise control connector 🤔. Do you think those wires are hidden inside of the controller box?
