Lexmoto lowride 125 battery and wiring

[Jamieswann]

Hi there, just looking for a bit of advice not being very mechanically minded or electronically minded I can't seem to find the fault and I can jump to fifty conclusions and it'll be the fifty first solution that I didn't think of

 

When starting my lexmoto up I have to have all my lights off and everything turned to 0 essentially, as this is the only way I can keep my battery above 12v 

 

If I turn on all my lights to start the bike I'll get 3 or 4 good starts off the battery before the battery dies. But it doesn't 100% die it dies enough that it won't start with the lights on.

 

But it will start with the lights off as the battery will be above 12v 

 

I've tried charging the battery with a smart charger and it's been fine.

 

So I guess in a long winded way of asking is there a way to find out if its the battery itself that's the problem, the wiring is faulty somewhere and may have some cross leads, or is it my lights themselves and for some reason they are drawing way too much electricity. Willing to supply any pictures or more information if needed 

 

Thank you in advance for the advice

Batteries on small bikes take a bit of a beating really and unless you do a good hours riding with the revs up you probably dont put enough back into the battery for the omph you used starting the bike up. Plus you have the lights on indicators and stuff so the battery has a hard life. Throw in winter and cold and you can knock 25% of a good battery before you start. How old is your battery? if its getting on a bit it may pay you to keep it on a trickle charger to keep it topped up and have your lights turned off when you try to start it. Plus a alternator doesnt really start putting charge back into the battery until its reving over 4 thousand revs, so you can see how they can soon lose its power.

I can't say for sure at this time how old the battery is but I do have it in my paper work and I'm sure it was pretty recent, but that could be 6 months or so, so before winter for sure so will double check that first.

 

If its pretty new and barely been used what would be my next port of call to look at? Just trying to learn for the future and all the fault finding I can learn now is helpful
