I can vouch for hitting the bottom of the battery lol that’s with a full blown sound system, pioneer head unit, subs, amp, rock lights, 42” led bar, reverse pod lights, low and high beams. I think I might be missing a couple things. It took a while to get there but the machine did not die, the worst I got was a headlight flicker. I shut a couple things off and it charged up fairly quickly. Granted in no situation would I ever run everything at once as it’s a bit extreme but I did want to test the limits. I also carry a 1000 CCA portable jump starter in my safety pack just in case me or friends get stranded. I plan to switch to a 40 series AGM battery with at least 80 AH. Stock is only 35.From what I'm reading and correct me if I'm wrong. We have 250 watts of charging power from the stator. So, anything higher than that has to be coming from the battery. So, if we draw more than 250 watts of whatever for whatever, the charging system won't keep up. Also, we are sucking power for the stock lights, tail lights, and other stock functions. It's fine to run say 500 watts of light for a while but will eventually kill your battery as the stator can't keep up. So, more than likely, you could run about 225 watts of add-on lights and you would be ok, anymore than that, well, eventually your battery will die even while running. Now, I thought for those that want 500 watts of light, you could cycle them on for about an hour maybe more, then shut them off and allow the battery to fully charge while riding and using stock lights, then turn them on again. This is why vendors offer a 60 amp add-on alternator which is good for 720 watts continuous. any comments welcome.
The circumstances I put it through wouldn’t be a common occurrence. Having everything on at once is never a necessity. But I did learn the limits. Since then it’s never happened.If you get to the point your lights are going dim or start to flicker because of the draw on the battery ... your stator has been pi$$ed for a while leading up to that point!! You may do it once, you may do it 20 times but eventually you will have issues with the stator, wiring, connectors or regulator. Typically when the problem starts, it shows up in burnt connectors and/or what is diagnosed as a bad regulator. Then ends up with google searches and forum questions on how to test the stator!!
