[fly boy]

hey guys
hopfuly next week i can order something
ok after readig lots of threds on chargers for lipoly its seems to be
inless i get a 160 doller charger my batts will never be any more than like 80%
to 90% charged acording to some people all thees cheap chargers do not do the last 3 stage charg on lipolys.
can some tell me if this is true.
im mainly looking at E flight lipoly charger but have heard its thame as the hobbico one dosint fully charg lipolys.

I use a basic old Swallow.

85 bucks Australian, My 3 cell pack is rated for 840mAh, after a full flight on my foamy the swallow puts back 820-830mAh.

I think some-one might be having you on. Basically the charger charges at the maximum rate you set untill the cells reache a predetermined voltage, 8.4volts on a two cell pack.

Then the charger slows the rate to keep the voltage constant at that 8.4 volts, when the charger reaches 0.05 amps it terminates the charge. I have verified this by putting a voltmeter directly on the battery whilst it is being charged.

I think you will find that a good cheapie is fine, I dont know anything about the chargers your interested in though.

No... I have tested several batteries on a CBA battery test program and they sometimes charge 100%, but may not stay there... dropping to 90% charged. A balancer is nice, but you dont need it by any stretch. Dualsky makes a very nice affordable lipo charger.... $50 or so..

I got an Apache Li-Poly charger and a thunder power 11.1v li-po pack rated at 2100mah. The charger can be selected for 2000 or 2500ma with a jumper, which setting should I use?

I have your exact set up. I charge mine at 2500.

Hi Mike,

You probably already know this, but charging your 2100 packs at the 2500 setting in a NO NO! I think you're doing a serious disservice to your packs, not to mention it's dangerous.

I have the same charger and always charge packs at settings LOWER than your packs rated C discharge rate. In fact, if you have time, you should always try to charge your packs at around 0.7C just to reduce the stress on your packs. I usually charge my 2100 packs at 1700 or less if I have the time, and even then at a MAX of 2000 mAh!

On my Kokam Li-Po instructions, it says that you can charge a Li-po at a rate of 0.5 times bigger than itself.
E.g. a 750ma could be charged at a 1000ma, or a 360ma could be charged at 500ma.

Thats what I have read, and what i have done and I have not had any trouble.

Thanks

I say when it comes to lipos always follow
the instructions unless you live for danger

A decent charger will run you in the area of $90 to $140 USD. I have a couple of Orbit PocketLaders that do the job JUST FINE!! They are single output, but for me, thats all I need! I have a couple of lower end chargers also. They work JUST FINE, too!!! The EFlight is an OK charger. I don't think that it gets packs all the way up, but only speculation there. I do not have any expeirence with them, I'm going on what I've heard others say about that charger.

The Hobbico 4 in 1 charger is a good charger, only thing I dislike about them is that you cannot set the cell count. I like to know that I'm not goofing up when charging Lipoly!!!

Japan3D- Set your charger to 2000mAh!!! NEVER OVER!!!! You will stand a possible chance at blowing that thing up!!!! Good rule of MY thumb on Lipoly, if in doubt on size of pack, charge at .5A, and look at the time to charge. If too long, bump up the rate of charge, until you get right around 1 hour and 15 minutes of charge, from a freshly discharged pack, of course.....

Any questions, please ask! We are all here to help understand Lipoly better. The ins and outs of them, and etc!!!

I have discovered that I can charge li-pos on my triton charger with the li-on settings. Does anybody use a trition to charge their li-pos?
