Hi guys,
So I have a GY6 150cc that I use mostly as a daily driver to work during the week, but come weekend I do not use it and after two days or so of no use, battery is practically drain and after a few cracks it dies. I have a deep cycle 12v car battery in my garage that I have sitting around which I charge up periodically to use on outdoor activities, my question was could it be possible to hook up jumper cables from scooter to this battery during those couple of days of no usage in order to stop or limit the draining? Am just tired of having to pull out my battery charger and wait for hours to charge up again.

Connecting directly to the battery? Don't think so. Get a voltmeter and test the two batteries and you'll see the difference. Connecting an adapter to the car battery would work though.

maybe someone can help you figure out what is draining your battery. wish i could help but i'm rather clueless with electrical issues. but it should hold a charge for weeks without issue.

So I take it a straight jumper cable hook up left over the days I don't use the scooter wont due much help.
Being that I keep the scooter outside the simplest thing for me is to post up that deep cycle battery next to it, rather than running extensions back to nearest home outlet which I think a battery tender would need if am correct.
jjoshua you mentioned "Connecting an adapter to the car battery would work though"
What kind of adapter do you mean?
Options:
1. Splice the Battery Tender Adapter's AC cord and connect it directly to car battery. (Unsure of outcome)
2. Perhaps invest in an inverter 500-750w so I can plug in the Battery Tender and run from battery.
3. Slap a solar panel on the scooter, lol..
Any other ideas?

Hm. I vote for the solar-powered scooter. You might even be able to get government funding to develop it!  >'Kat |

Actually they do make solar battery chargers. I'd check the condition of the battery. Letting it sit over the weekend should not be a problem. My 150cc scoot has sit for weeks without any problems. I do have tenders but I forget to hook em up.

If you connect the battery it will run down quickly as batteries will equalize.
Just use the battery to jump start the scoot and once running will charge the scoot battery. Best guess is bad battery or inadequate charging.

Most scooter batteries are under 10 amps where a car battery can be 450 or more amps and be too much for it . Most trickle chargers put out 1/2 amp so it is a safe and slow rate of charging . I have the Harbor Freight one it works fine but I wish it had a meter like the Battery Tenders often do . Mine only had a red LED that lights up once it is hooked up to the battery . BT has optional quick connects to avoid removing the battery cover to charge it . I have let my 2T sit for over a month and the battery was still good . In the winter time , more so up north the cold will drain a small battery in a short time .
It should start up with the kick start as it runs off of the stator and the battery if for the starter and blinkers . Do you have an alarm ? I read where some alarms can drain a battery just like a mild short can too . A trickle charger is a great investment for not much money .

howdy, I have found through using truck batteries in parrelel and tandem, that one bad cell will drain all the batteries. so, If your small batterie has one bad cell causing it to drain, then hooking it to the larger rv battery will drain both where normally it would not hurt since the voltages are close to the same values at approximately 12.7 volts at rest. if the small battery remains hooked to the scooter circuit which is draining it overnight , as long as it was a smaller wattage drain, the larger battery would provide reserves enough to start the scooter in the morning. so to re-iterate , if the battery itself is ok and the drain small, doing what you propose would work and not damage anything. in that case the other obvious answer is to disconnect the battery from the scoot each time you park it.
lotsa miles and smiles to ya

The amps in a car battery is wayyy more than a little scooter battery. Amps measures current. You know how some batteries have normal and quick chargers? Well the quick chargers have more amps. It charges faster but is bad for the batteries lifespan. A car battery would probably overcharge in in less than 30 mins and kill it. 1.Won't work. The insides are made to convert ac to dc, but i'm not an electrician. I could work. 2.I think 100-150 watts would be plenty ---->>>> www.rapidtables.com/calc/electric/Watt_to_Volt_Calculator.htm3. You could build a 12v solar panel. I would make it stationary and park the bike next to it vs, on the bike. Sounds like something is slowly killing your battery (Alarm, other accessories) Or your battery is on its way out. I would put my money on it gong out. Does your kick start work? I would jump the battery and let the battery charge as you ride. If it doesn't your battery is most likely dead or the bike is not charging properly. |

Lets find out what is causing the depletion of the battery, if something is depleting it solar polar whatever is not going to help.
You have to find the cause if it, So the question is what do you have on the Scoot?
1. Did you add any accessories?
2. Does it have an Alarm system?
3. Does it have Remote Start.
If none of the above then you have two possible conditions:
1. Bad Battery that will not hold a charge.
2. Your Charging system is not charging.
The battery you can take to just about any Auto Parts store and have them check it for LOAD.
Most batteries will show good voltage with a multi meter but if it has a bad cell it will not take a load. That is what they call surface charge.
You need a Multi Meter to test if your charging system is charging. You can pick one up cheap for under $10.00 at Harbor Freight. Start the scoot and test and see if it is charging at IDLE, then rev it up to around 4K and see if the charging rate goes up. If it doesn't then it is one of two things Your Regulator/Rectifier or your Stator. The Stator can be checked so if that turns out good then you know the Regulator/Rectifier is bad.
If the Stator does not produce around 40Vac-100Vac then you know your stator is bad. Then once you get a new Stator you can check if now it is charging If still not charging then you now know that your R/R is also bad.

You have something draining the battery or a bad stator, regulator or battery as alley says. Find the issue and replace the bad part or parts using a stronger replacement battery isn't the answer. Its like fixing stuff with tape or glue instead of getting a replacement part.

Its like fixing stuff with tape or glue instead of getting a replacement part. My Grandmother fixed a lamp plug with scotch tape. The side of the plug had broken off so that entire metal prong was showing. Thrifty lady that she was, she just taped around it, I suppose so the prong wouldn't fall off. Then she continued using that lamp.  >'Kat |

Thanks to everyone's suggestions.
I do have an alarm/radio unit, so based on some of the suggestions most likely this will be the culprit, plus I do have about 4500 miles on the original battery so I will also have it checked, as some threads recommend to change it out upon getting a Chinese scoot (Motobravo Phantom GTX). Also no kick starter took it off.
In addition I took the liberty in ordering two Coleman 2w Solar Panels to assist in maintaining full charge, going to try one for the scoot and one for the deep cycle battery, or I guess I could do both under a parallel setup for just the scoot if need too. I will see if this works, plus I figure they can come in handy if the grid ever goes down lol.
