Battery and Charger Help
I am going to my first electric ( 3d hobby AJ SLICK 51" or Extreme Flight 48" Extra EXP) and will be purchasing a 4SP2500 or 4SP3200 @25C using a 14x6 or 15x6 prop and need help with a battry source and a good charger. How many batteries will I need to make several flights per day and can I recharge at the field and what would the recharge time be.
Thanks
Ron

RE: Battery and Charger Help
Ron, I generally try to keep at least 2 battery setups per plane, soI can fly while a battery is charging. The charger I use is the Triton EQ by Electrifly. It can charge up to 5 amps, has built in balancer, and built in AC converter with cord. It's a bit pricey at $129.00, but it's been a good charger for me so far. You can connect it to your car battery to charge at the field if there's no 120v plug in available.
It charges NiCads, NiMh, LiPo's, and Lion batteries. You can also discharge and cycle also.
As far as a source for batteries, I have been using Zippy LiPo's from Hobby King. They have been working perfectly for me so far, and the prices are very affordable.
As far as charge times, you can safely charge Zippy's at 2C, so you can expect 1/2 to 45 min recharge time on average, but it's going to depend on how low you discharge them. Might be longer, might be shorter.
Hopes this helps.

To charge a 3200mah 4s pack at 2C you need 6.4 amps and and at least 75 watts. At $79 it is a charger. You will need a 20 odd amp power supply.
Check out Turnigy Accucel-8 150W 7A Balancer/Charger

25A 14v DC Power Supply for Chargers (350W) or a 12.5 amp model at $29.95

RE: Battery and Charger Help
While the Triton 2 is a good charger it does not have a balancer and is $119 vs $79 for the Turnigy. Also you should NOT charge at 2C without a built in balancer that will monitor for a high voltage on one of the cells and stop the charge if needed. We have two Turnigy chargers at the field and their owners are very happy with them.
I am looking at buying two or three of the Turnigy 50w chargers for $39 to charge my small 2/3s 1320mah and less packs.

I come up with 50-60 watts for 1C and 100-120 watts for 2C charging. A triton2 would be perfect since it has 7 amp max and 90 watts max.

RE: Battery and Charger Help
Good info. I was about to post a similar question. My FMA Cell-Pro works great w/built in cell balancer. The 12 volt charger looks like it should replace those 12volt batteries that I keep for my Nitro planes as they wear out and cannot hold a charge for this type of use. !!!!
