Electric Belt Starter Issues

[Craig Hollingshead]

Good day: I picked up a electric belt starter, a new TFL Hobby. I am using a 19 inch belt, a 5000mAh, 100c, 4S, 14.8 battery. My engine is a Zenoah G300 marine with approximately 10 hours on it, so it is not new. The battery has a full charge. The starter will not spin the engine over more than once, then the belt starts to slip. I am pulling up quite hard. If I pull the plug, obviously it spins over very easy. What am I missing??

You need 24 volts or 22 if 6s Lipo 5000 mah and 50 - 75 C

 

[Bill Gibson]

I agree with Tom, it sounds like you need more voltage!

 

[Mike Hughes]

Those TFL are designed for 3-4S. Is your battery good? It might be weak. Fully discharge it at a high rate and see how much you can put back into it. DId you lube you motor? Oilling a gas more with after run can locked it up and make it difficult to turn over with a starter.

It is a new battery. I will try a full discharge and then charge it back up again. It is not locking up.

If the belt slips I would try another style belt.Does the belt fit the pulley correctly?

 

[Craig Hollingshead]

New belt and it does fit correctly. I think my battery is not up to snuff. Trying the discharge/charge

 

[Roxyflash]

What kinda belt is it if it slips the battery should be good unless it slows way down.

 

[Mike Hughes]

Cycle it a couple of times to make sure you are getting full charge. You should be able to get 4K mAh into it each charge after full discharge. If you not getting that then we need to check the charge settings are correct. I would check output voltage as well.

Are you using the black v belt?

 

[Craig Hollingshead]

I am using a Speedmaster belt. I got 4.8Ah into the battery after a full discharge. I am doing another discharge/charge cycle

take the plug out and turn it over blow out any fuel or oil then try it

Get you a 2L v belt in your choice of length. They grip and last much longer on gas engines.

If the belt is slipping, it's not the battery. Get the right belt as others have referenced. I use gates 2L190

 

[Craig Hollingshead]

Is this the correct one? 2L Belt Type X 1/4 Inch X 20 Inch Outside Diameter. The 19 inch one I have in Speedmaster seems to be an OK length.

That will work. 2L is the width. So as long as it’s 2L your fine.
