Default Best A123 capable (and Lipo, etc.) charger.... ?

I'll be needing an A123 capable charger for my airplane rx packs. I might as well get one that will charge everything else as well. An AC power cord plus CD input would be nice. It doesn't have to charge more than one battery at a time necessarily or at high amperage...... SO what would be a good charger for the buck? Imax, FMC, turnigy, or????

It boggles my mind, LOL,

Thanks,

Ernie

Take a look at the CellPro line of chargers. I have a Multi4 and it is great.

ditto on the Cellpro charger. Mine are set up to charge between flights while I refuel. Works great.

I dont know what the "best" is but I get a lot of milage (chargage?) out of my Hyperion Duo3

Its firmware upgradeable and I can even plug it in and run it and chart batteries and stuff with my laptop. (cuz i'm geeky like that)

FMA imports and sells Cell Pro. They are made in Asia.

Got two Thunder AC6 chargers and one CellPro Multi4. Kind of like Thunder AC6 better, but I haven't used the CellPro enough to get familiar with it.

Mike, you are just using one lead to charge/balance through? I thought it takes two leads to balance.

Thanks,

Ernie

Ernie,

Receiver A123 packs are two cell so the balance tap is run through the signal pin of a standard JR three pin connector. This line goes to the charge port but is isolated from the receiver.

Sorry, my mistake. All my A123 pack are home made from Dewalt packs. I solder my own 20ga JR extension to the pack. I made up a mating connector for the Cellpro.

Stan, very cool that you are just using one lead to balance charge with. In another thread a couple of the top profile guys are just using two pins on the JR plug and not even balance charging. They say it's just two cells and for rx use has been no problem whatsoever. Interesting.

Thanks,

Ernie

Hangtime Hobbies makes a 2 cell A123 pack with a single lead for charging and balancing. They sell a charging lead that has the balancing connection. Need to read through their instructions, but it all works well.

I've bought from Hangtime Hobbies before and his products and service are outstanding.The website is very informative too.

I'm slowly switching to all A123s with the single lead. It makes charging easy as heck right through the charge port/switch on your plane.He nowcarries the Hitec 4port multi-charger with optional singlecharge/balance leadswhich I think I'm gonna get. I currentlyuse the FMA CellPro Multi4 with the custom single lead, it's simple and works like a charm.

Ditto for me! Go to www.hangtime.com and you will get plenty of help with A123 batteries. He is a reputable supplier, sells quality batteries, gives good service, and specializes in these batteries. He'll respond to your questions promptly and provides good information.

Anyone get a response to email from Hangtime lately?
I sent one a week ago and got no response from him.
My buddy wants to buy some things and just needs clarification on a few things.

Kind of hard to do business and click that, "Add To Cart" button under those conditions...

Maybe business is good and he is too busy.

I didn't set up balance leads on my A123 packs either. Someone very much into testing said exactly that. At low charge rates anddischarge rates, they would not get unbalanced.
Been over a year for me with over 1/2 dozen packs and A-OK.

Wow, intersting 4*60. Keep us posted, I hope that trend continues good with NO balancing your 2 cell packs. I might try that as well.

Do you still have your 4*60? What engine did / do you run???? Nice planes!

That's odd, I emailed him with a question last week and he replied back that same day. We actually exchanged a few emails. I've done business with them twice so far and it has been very good.

I've bought lots of stuff from him too.

I'll try again.

Is there a way to reach him by phone?
