Adding heated clothing will battery handle it

[Alberts46]

2011 RT SE5, has multiple sets of LED lights (8), heated seat, heated grips, etc. Will be purchasing Gerbing heated jacket liner and pants liner and wondering if battery will handle it. Looks like the battery on 2011 models was 12volts/21amps/hour, sealed maintenance free. Looks like the jacket liner might be a 6.4 amp draw and guessing the pants liner will be close to the same. I have several friends with Harley's and BMW's that have the clothing with no issues, but just checking before I purchase.

AMP DRAW

Those HD's and Beemers don't have Magneto's for producing power........your's does and it is practically maxed out in stock form.........I'm sure their are folks who have done this, if you do, wire it so it will only get power if the engine is running.....and always keep your battery on a Maintainer.......Mike :thumbup:

The battery has nothing to do with it. It supplies power only when the engine is running. The real factor is the magneto output which is 650 watt at 2000 rpm. So that's 55 amp. The Spyder needs about 20 amp average for the basics. 5 amps for recharging the battery when it is very low. So that leaves 30 amp for you to play with. So IMHO no problem. Just make sure the power to the heated suits is switched so it does not run down the battery when not running.

so if you have a amp meter turn on all your stuff and check the amp reading to get what you are drawing on the charging system..Or go to the auto parts store and borrow one..

Billy,
Are you sure about the magneto's output at 2,000 rpm? I was told that it needed to be spinning a whole lot faster than that... :dontknow:
If you've got some hard facts; I'd appreciate knowing it! :thumbup:

In reality the Spyder will have more power available then the OP's HD buddies and about the same as his BMW buddies depending on the model.

That's just too complicated. It's a lot easier to use a volt meter. With all your stuff on. If the system voltage is 12.8V or less at idle the electrical load is too high.

Thanks, Billy! :2thumbs:
I knew that it was 650 watts; I didn't know that there was more information just than that available right in the manual! :bowdown::bowdown:

It all depends on your charging system what it puts out at idle..I don't think they will be idling while running with all there gear on for long periods of time. So at 2000 RPM you are producing 55amps at 650 watts..Which on a spyder is like 1 second of driving to get to that RPM.

Its not complicated to check amperage with a meter..

I have been wanting one of these
