It's been a while since I have flown RC. Now my girls are older and want to try flying, we are starting back up. I have a 42% dalton. I had 2x3800mah Li-Manganese Duralite batteries for the receivers through a powerbox royal. They are worthless after 8yrs of not being used, and I was wondering which batteries everyone is using now?

I liked the fact I didn't have to balance them, and I could get over 10 flights without charging. I have the duralite charger and a hitec x4 80 charger. I don't want to have to buy another charger. I have been considering the Jeti 5200mah, duralite li-ion (but they only have 2800mah and then up to 5800mah), and the thunderpower prolite (but they have to be balanced directly).

I appreciate any feedback. Thanks!

Fromeco Li-ion. Lots of flight time and easy setup without having to balance. About as simple as it gets.

Great to see you getting back into it Pride!

PowerBox USA has batteries

Fromeco LiIon has been my favorite for many year, so we started offering them to our customers.
On a 40% I use two 5200 mAh on the receiver, one 2600 mAh on the ignition.

Li-ion's like Fromeco or Duralite are great.
I use A123's from http://http://electrodynam.com/store/EDN.html

Here are some of the pro'sand con's:

How many flights can you get with 2 5200 batteries? Must be a ton!

sorry

I have been using 2x 5200 mah 7.4 volts Duralite Li-ons with Powerbox for many years and you can get between 8-9 flights on one cycle charge about 10 min flight time.

Do they come with a charging lead? So they don't have to be unplugged to charge? It doesn't say on their site, and they aren't in until Thursday!

Yes, it comes with a separate yellow charging lead in which you can install on the side of the fuselage for charging the battery and checking the voltage.

So I found I had 2 fromeco 4800's in an old plane. Maybe 7 years old. They had 3 flights on them, and were still charged. I have cycled them about 5 times, and they take almost 4000 mah. Do you think they would be safe to use? I wonder if they do "go bad", it would be gradual, and likely not at the same time.

I would assume, that they would still be fine , but for how many flights??? not sure, and you should verify the voltage regularly after every flight. If the voltage drops rapidly do NOT fly.

If the loaded voltage below 7.0 then stop flying and recharge! Like above check voltage before and after each flight!
