Q: What gauge is the supplied wires?

The kit comes with 7 AWG wire, but wanted to comment on the customer who stated that it is not enough for a 20 foot run. At 140 amps, you would need 1/0 AWG wire, but with 95% of the applications out there, the most current that is drawn is around 30-50 amps and that is why we designed the kit with 7 AWG for the 20 foot run. I hope that helps clarify.

Q: Will the alternator charge battery 2 with this while car is running

Yes it will. That is precisely one of the features it is designed to do. Thanks

Q: I have a 2020 wrangler with a 240 amp alternator. is this rated to work with my alternator? i will be adding a second battery for low-draw accessories

Hello, a 240 amp alternator is definitely a big alternator, however, it is rare that an application would draw more than 40-60 amps at any one time. It is not so much the alternator size that would cause a problem for our isolator it is the draw from the accessories. I would recommend adding up the amperage draw from your accessories when they would all be on and determine the draw, if it is under 140amps then it will work well. If you decide to go ahead and use our Keyline Battery Isolator then you may want to install a large 140 amp fuse or breaker to ensure your alternator won't fry the isolator, but again that would be a rare accessory draw application like an induction cooktop or something similar that would draw over 100amps. Remember that the alternator is only going to push enough amps to power the draw of the accessories and to charge the battery (which also has a low amperage draw). Hope that helps. Thanks for the question.

Q: can this be use to charge a lithium batteries on the second battery?

Short answer: it depends. Longer answer: it depends on the Li bank capacity, battery charging specs, alternator specs, resistance of the entire circuit, etc. In my case I replaced 220Ah of flooded lead-acid with 100Ah of LiFePO4 and demand on the alternator actually /decreased/ a bit. If the isolator is already installed you could test it briefly to see what voltage/current from the alternator is like. If you do not already have the isolator a DC-DC sized to your alternator's rating would be a safer bet.
