    18V Lipo Battery?

    So last year i bought an 18V Lipo 8 cell battery, and now I am finally around to doing the wiring installation, I'm wondering if using this battery is going to fry any of the electronics (dynatek 2k, quick shift sensor ect.) or if the regulator/rectifier will step down the voltage? I am using a new Honda RR.
    Thanks-Rob

      Ditto....18Vs is a bit much for a 12 volt system no?

      Stuff I've done to my bike:dancing: 1100E front end with new Sonic springs, 1100E swing arm conversion with new Progressive shocks installed, 530 sprockets/chain conversion, new SS brake lines, new brake pads. New SS fasteners through out. Rebuilt carbs, new EBC clutch springs and horn installed. New paint. Motor runs strong.

        NO as in HELL NO, you can not do that. If you do that, it would be best to take the easy route to the same end. Pour gas over the bike and set it on fire.

          you need a 12 volt battery not 18V.

            Unless it has a tap for 12V DON'T use it IT will fry the electrics.. even then you would need a special charger

              thanks guys, I bought the battery off of ebay in fact here is the link to the same item. it says 13.2 however when i measure it with volt meter it reads 18.43??? over charged maybe? i had it on a 12v slow charge for ~3days?

              My apologies I should have clarified that the volt meter is reading 18v not that the battery is supposed to be 18v

                Whew...okay that is better. 18V is a bit overcharged, think I would try and drain it down some before I was to hook it up the system.

                  i dont think 4.6AH will be man enough to start your bike, it does say in the listing for bikes 50cc to 250cc. you need a 14AH battery i would think.
                  charging it to 18V may have cooked it anyway

                    my bike is kick only, starter has been removed, I sure hope I didn't fry it, It never felt hot or even warm to the touch, is there any way to tell?

                      it may be ok, wait until its fitted and see if it works ok. for those lipo batteries you need to get a trickle charger that automatically cuts off at about 14V so it wont cook them

                        A standard battery charger should not be used on them at all. If you do blow a Lipo battery up, the explosion will be severe and the cloud toxic and possibly fatal if you are near it.

                          no they dont, a normal trickle charger works just fine, as long as it has a cut out function to stop it over charging.
                          dont use a "normal" car or bike charger either as the charging rate is to high.just use a trickle charger

                            The problem with that approach is that a GS doesn't have trickle charge mode.

                              the LiPo's work perfectly well with the standard bike charging system, i have a Ballistic 8cell battery and it clearly states in the instructions that if needed, a normal 12v trickle charger will be perfectly fine as long as it has a cut off point at around 14v to prevent over charging.
                              a special Ballistic charger is available but not neccesary.
                              as the battery only loses 10% of its charge over a year, a charger should not really be required at all
