Has anyone used this to charge a vehicle with dual batteries?

I use it on my boat but jumper the batteries in parallel to 12v. But it is a 24volt series system, I asked Amazon like you if I could use it on a 24volt system and never got a response from anyone....So I did the parallel thing only to charge them.

Yes, I have been using mine while charging with the USB in my vehicle. No issues.

No Joan, it can only charge 4 or 2 batteries at a time. I tried three and the "green light" never flash to indicate that it was charging; plus there is no 3 battery selection at the top - just 2 and 4 batteries. But this is an awesome product, great price and you get a car charger for those long trips for your kids hand-held games; keeps them happy and preoccupied while you drive. It also charges other rechargeable battery brands (Energizer and Duracel)

I am using it on my SeaDoo and just purchased a 2nd one to wire into my Prius for it's smallish 12V battery. So far it has worked great for my jet ski which doesn't get used a lot. The battery in my Prius didn't work after over 2 weeks in my driveway. I am not using a charge controller. The jury is still out on long term results, but the documentation says one is not needed.

Yes. It charges the battery, one at a time. Very easy to use, two lights - charging and full.

No it does not, BUT i've had it for about 3-4 years now and have never had a battery over charge. ALSO one key factor when wanting to run a dual battery setup is to start off with 2 new batteries that are the same make and model and pre-charge them before putting them on a vehicle.

Yes this will charge 2 lipos at the same time. One on each side. It works with all types of lipos.

I don't know, sorry I cannot answer that, however I am sure it is safe to charge 2 batteries.

Yes, the newest version of these charges support charging both 12v/16V LiPo batteries. Just make sure you have the mode selected (its the blue icons on the front of the charger)

I use it to charge 2 iPhones at the same time- an iPhone 5 and an iPhone 3S. It does an excellent job. I found the seller very credible. If he say it will serve your need, I belive he will refund your full purchase price if it does not. I would buy it and give it a try if the seller says it will work for your application.

I have not tried to charge two batteries at a time. I would recommend you to reach out to Traxxas Techline for a trusted response. These systems and batteries are dangerous, so I would follow the manufacturers recommendations.

It can charge up to 4 batteries at a rate of 6 amps each. A 20 amp could do the job if you are not charging 4 packs at full capacity at once. A 30 amp power supply is a safe place if you are going to charge multiple batteries at once. Here's a good 20 AMP supply. Racer's Edge 20 Amp, 13.5V DC Dual Output RC Power Supply with USB

there is no way to charge 2 NiMH batteries at once? adapter board such as the one for lipo? is there a dual charger designed to charge 2 NiMH batteries at once?

I haven't tried it but you should have no problem charging bat and device at same time. Think it will detract from bat over long run but should work

Not positive here, but I would be hesitant to use this charger for that purpose and I wouldn't even dream about it if they are in series. (I would dare to believe that they are parallel though.) I would feel okay with 2 standard automotive batteries wired in parallel, but I think you are asking for a short lived charger on anything more than that.

I would not since the charger senses your battery and goes to float when it reaches charged state so with 2 it may overcharge a battery, also this is a very low amp charging system so it would probably not do the job on 2 batteries.

yup, works fine charging both at the same time. Make sure you got one bank to one battery and the other bank to the second battery(in other words, don't mix the two banks from the charger up).
