Hey guys , I've got a working led tusk brake light and i'm also trying to power a 3W polisport LED headlight, pretty much all I need for riding.

i'm using this battery http://www.trailtech...40-BATT3.7.html however i was wondering what options I have for buying a battery that comes with its own charger and maybe a little more powerful? I'm using a random battery charger to charge this one and it doesnt last too long. my aftermarket stator blew out so i dont want to buy another, just go completely battery.


also i cant seem to get my led headlight to work, I know its not the control switch because the horn works, the headlight has 3 leads: highbeam, lowbeam, and ground. The contrl switch has 3 leads, highbeam, lowbeam, and headlight main. I heard I'm suppose to be grounding everything to my battery system though so I'm confused what to do with the ground wire.

any help is appreciated, thank you

That battery pack must be spent, I use a 1800mAhr and it lasts at least 2hrs with my LED headlight and tailight.
I got it off eeeeebay for around $10 with a charger.
Heres one like it but no charger.http://www.ebay.com/...=item43ae4f2e4a

I don't know what a "headlight main" is but it's probably a ground.
All grounds go to the black wire on the battery.

LED lights will not light if wired backwards.
I built my own DS kit and used a mutimeter and car battery charger for testing as I went. I always end up taking the switch apart to see what color wire controls what function.

Try bypassing the switch and hooking the headlight directly to the battery(using a fuse in between) to figure out how it needs to be wired.
If you have a car battery charger it's better because it has a beaker that will trip if you accidentally connect the + and - together. I like to set the charger for 2 amps.

Well my battery can power my LED headlight for like an hour but its only at its brightest for maybe the first 20minutes, I'm charging my battery with a car charger at 2 amp 12volt,   but im only charging it through my regulator/rectifier just to be safe, (my bat used to be hooked up to my stator through the reg/rect so i knew that would be OK to give it power that way)

I usually charge it like this for a couple hours. Do you think I can charge it directly to maybe get it more power (no regulator/rectifier)? if so for how long?

Also.. I'm looking at this battery pack http://www.ebay.com/...#ht_2058wt_1163
but i'm wondering, should i buy an actual battery charger while i'm at it? and is there any way I can make use of 2 batteries to combine power somehow?

I just need bright lights for <2hours

thanks a lot for the help, should be on the road soon here.

I wouldn't have a clue how to properly charge the battery you have now. If your gonna get a new one anyway try charging it longer. 4hrs? then 6?
I would suggest getting a battery and charger together. Even though mine came as a set there were no instructions and the LED on the charger never seems to change color or go out. I just charge mine for 6 hrs or so with its own charger.

FWIW my kids power wheels have giant batteries and they say to charge for 24hrs no matter how long they were used before charging.
And my cordless drill says you can leave it on the charger all the time. That LED on the charger never changes either.

If you combine 2 batteries you'll end up with 24volts and blow everything up. You can use 2 and just switch em out when one dies to get double the run time.

No I think you can wire 2 batteries up @ 12 volts if you do it right

yea, parallel 2 batts still 12v,  series 2 batts= 24v just google parallel wiring, very simple
