Default multi charger for aerobird challenger

I am trying to find a charger that will charge the 6 and 7 cell batteries that the aerobird challenger uses (2 or more battery packs at a time). When I started looking around on the web I realized there are several hundred chargers available and I did not know what I was looking at. Would someone please recommend a charger that would work well for this. I'm not looking to spend more than $100. Thanks

Your choices for multi-port, peak detect chargers are pretty slim. Most can only charge one battery at a time. One of the big reasons for this is that manufacturers feel the cost of such an item would scare off most buyers. That inexpensive $40 Hitec CG340 (which I highly recommend) would cost $80 in a 2-port version, because to make a 2-port charger, you basically have to put two one-port chargers in the same box. Imagine a 2-port version of the $129 Great Planes Triton. At $258, the demand for such an item would be small.

You want a charger that can do peak-detect, that is, it can tell when the battery is full automatically. You also want a charger that can charge more than 8 cells, so you don't have to buy another one later when you go to larger airplanes. That's why I like the Hitec CG340. It's inexpensive, easy to use, compact, capable of charging up to 16 cells, and it does the job well.

Like most chargers, the CG340 is a 12V DC-only charger. You need some sort of 12V power supply to run it, like a car battery. There are two main reasons for this. First, the charger would no longer be compact, lightweight and portable if it also contained an AC power supply capable of running it at its full capacity. Who wants to lug a heavy brick to the flying field? Second, adding an AC power supply would drive the price up, again scaring off buyers.

Thanks, that information is definitely helpful. The plane comes with a single port peak detect charger, but I wondered how much drain on the car battery it would be to charge 4 batteries. My son and I both have planes with 2 batteries each. I'm trying to figure out a way to charge all 4 so that we can go out and fly for more than 15 minutes. Thanks again

Some people use those "jumpstart" battery things that have a 12v outlet on them, then you could be charging two at one time and not worry about your vehicles battery, plus if you ever need a jumpstart there it is I bought one from harbor freight for $49, I can charge it at home and then use it and then charge it again, works well.
