Charging Capability

I am not very good with electrical so wondering if anyone can answer my question?

My wife and I would like to load our inflatable paddleboards on the bikes and ride, rather than drive to our destination. I have a 30 amp pump that hooks up to a car battery and wondering if my 2016 DL1000 will be able to handle charging off the battery if the bike is running at idle?

Oh man not sure I would try that, the mini pumps we use to inflate our bikes with don't pull anywhere near that kind of amperage.

12v*30A = 360 watts

The new vees make 490 watts at 5,000 rpm, but after all the other loads (lights, ECU, fuel pump etc) it's probably cutting it close even at peak output.

I don't think I'd risk it, but I'm sure someone on here has an EE degree and can give more informed advice.

Depending on how long you run the pump, the battery combined with the generator should have lots of capacity to run the compressor. Just try a test run in your driveway and blow up the paddle boards while monitoring the bikes voltage display. Rev the bike up to 2500 to 3000 rpm (or more) if the voltage drops much below 12.6V. I have a ATV with a 200watt generator and same size battery as the v strom and have run a winch with the engine @ idle for extended periods with no ill effects. The winch draws 80 or 90 amps at full load.

The battery has a capacity of ~ 10 amp-hours (can do 10 amps for 1 hour, 20 amps for 30 minutes, etc.). However your battery is designed to deliver a lot of amps for starting and can be damaged by deep cycling (assuming it's a standard lead-acid battery). If you can pump up your paddleboard quickly then you should not have a problem. If it takes a long time then you may run the battery down more than desirable (in ten minutes you would draw 5 A-h assuming your charging system is just keeping up with the motorcycle load while idling). You could run the motor faster but who wants to stand next to a bike running at 2 to 3,000 RPM for ten minutes. You can always try it once at home and see what happens before you hit the road.

Agree with the two previous posters. If your charging system is not able to keep up with the power requirements, you'll simply run down the battery. How bad this is depends on the state of the battery and how long you need the pump for.

The main question therefore is: How long does it take the pump to inflate those paddleboards? If we're talking a maximum of, say, 10 minutes then you don't need to worry at all. Anything over about 20 minutes would require some detailed calculations.

Having said that, a lot of owners carry a small compressor to inflate the tires in case of a flat. Those pumps are typically small enough to be stored under the seat, and have a significantly lower power draw. If you can set this up with the right nozzle you can use it to inflate the paddleboard using the excess capacity of the charging system, so without running down the battery. This means less headache about the electrical issue, and less items to carry.

Thanks to all for the excellent advice! The pump I use does have an internal Lithium battery but I'm asking in a case where I needed to use it for additional boards. It takes about 10 minutes to pump the board up.
I will try it in the driveway and monitor the voltage draw as suggested.
I do have a tire pump and have used it several times successfully. I pick up a lot of nails and am an expert at plugging tires now!
Again, thanks for the help!

I was about to suggest a manual pump. And no risk to your motorcycle.

I used the 30 amp pump successfully plugged into the cigarette lighter accessory on my 2016 DL1000, to pump up my paddleboard to 18lbs (20 max). My draw stayed at 13.9v while running the bike at idle. It took about 10 minutes to inflate this military grade PVC board. I consider this a success!

Again, thanks to all the input the members here provided. I hope this will help others considering using this accessory plug in the future.

A cigarette lighter pug is normally rated at 10amps so things could get hot and start to melt with a 30amp pump.

A merit pug is only 16amps so a Anderson plug would be best.
