| Yup. If one battery is bad it will effect the other one. If only one is bad you only need to replace that one. I only use one 12volt with 12 to 1 compression in the bubble with no issues.....yet!

| I have a quick connect at my cut off switch and wired so if I cut swiitch off and battery could be connected and crank the car with main battery basically disconected. Now a 12v boosting 16v battery not sure that would work,It should be able to, but a 16v battery will not start if down to 16v. A 12v at 14 will spin same car great. Nev er under stod why unless amps are too lpow when battery is on bottom of power out put. Hopefully stated that so understandable.

| Featherlite sells a 16V jumper pack. I am sure it is one of their 16V lithium's in a housing but they do exist. Tesla also has one but it is not sold to the public only authorized repair facilities. https://www.feather-litebatter...ace-car-jump-starter

| Two of the four 16 volt batteries I have had were defective from the start. (XS Power S1600) One was really frustrating because battery would charge and it would start car a few times then just dead. After using 16 volt systems for years I would not recommend them. The 16 volt does spin it over faster when everything is good but it will let you down faster if it is not. One of my cars now has 2 of the 16 volt batteries and when they are done I will probably replace them with one 12 volt. By the way I run an alternator and keep the batteries on a trickle charger which in my opinion is best way to go. As long as they are still working I do not see a need to waste money getting rid of them now. I do not know if a 12 volt jump box will start a 16 volt system but I do know you will not have as many problems with a 12 volt system. We are drag racers we all think more is better but with batteries more voltage is not necessarily better. https://postimg.cc/gallery/np3zpruo/"Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion |

| Good input here. 12 volt jumper will not start it. We’ve had those issues and like stated; a bad battery will drag the others down too.

I don’t think anything will jump start a bad battery but I have jumpstarted my 16 volt setup car with 12volt jump pack before when I left waterpump and tan on when fixing a broken tab but my battery was just dead not bad or shorted. |

| I can't crank my stuff fast enough to start it with a 12v battery, which is why I went 16v. My daughters car has the same battery I do, a XS Power D1600. Almost new, got to the track and it was dead. Tried charging and still not helping. What I found was the alternator was killing it. It's a one wire East Coast Alternator, 16v, and while it's connected directly to the battery, it still pulls from it even when the engine is shut off. So we're installing a new cutoff switch that has terminals to kill the alternator connection as well. I've had mine for almost six years now and zero issues.....I'll never run a 12v in my stuff again. 16v all the way. I will be getting a new battery at the end of this season to keep on hand as a spare for mine, but I'll continue to run mine until it won't cut it anymore.

Absolutely. (if you are running a 16v alternator, you would need to disable that.) Also, you don't switch to a special 16 volt starter, so a fully charged 12v jump pack should work just fine to spin it.

Most times I am hot lapping the car and need to cool trans with Jones Trans pump. The 16v couldn't get me past the 3rd round - making sure it was also connected to a charger as much as possible and running an alternator. Burned me several times before I put two red top 12v and car cranks just as fast, maybe faster. And the two red tops dont ever drop below 12.2V with water pump, fan, trans cooler and trans fan on. Got to the quarters in pro, and finals of super pro last weekend and they were rushing the race due to incoming weather - those two batteries had no problem.
As for the 12v jumper pack. I have one of those golu (sp?) small jumper packs and it started my car no problem - see above is how I know. LOL. I dont think anything was wrong with my 16v battery it just didnt have enough reserve. If something is wrong with it - it might not work then. Try it. It wont hurt anything.
Last thought - if you have a 16v they are hard to find to replace at the track. If you have a 12v you can run to autozone and find one.
So when you tried 16 volt was it one battery or two and was the alternator the same ampacity as the 12 volt one?? Just wondering if you are comparing apples to apples here. I have doubled up running one battery and only 55 amp alternator and haven’t gotten bit yet. |
