Okay, as much as I enjoy the fun filled 6 minutes of flying my Belt CP v2 with the stock Li-po 1800 mAH 11.1v.20 and the 2.5 hour charger...where do I go from here?

I stayed out of the electric heli world because I didn't want to chase after the almighty battery...here I am

Any suggestions on a 2200 mAH and charger?

Thanks

you just opened a can of worms the size of texas

pm me for some smokin deals on a 2200mah battery

for chargers i am a big fan of the fma cellpro stuff,charge at 2C and have the batts fully balance charged in less than 30min,what you are looking to spend will determine what model you are looking at

My opinion may or may not be shared by everyone else here.. but..

Most of the people around her like the FMA chargers.. they can do some pretty cool stuff (computer interface, reporting etc), but it came down to $$ for me. I bought the IMAX B6 charger from http://www.hobbyking.com and then converted a computer power supply to a bench supply for it.

The IMAX does a fine job, balances, charges multiple chemistries etc, and is a good basic charger - I'd go for the FMA if it's in the budget.

My personal opinion on batteries - I don't have enough experience with lipo batteries to tell what's what.. but I've read a lot of good things about the Zippy's from http://www.hobbyking.com and I bought one.. it works just fine - but I haven't had that many charge cycles on it. I at least one friend who use the Zippy's exclusively and thinks they're a great cheap battery.

My zippy is a 2200.. and the extra weight is kind of nice since it moves the CG a little more forward as well as giving a little more time.

My 3 cents worth anyway.

EDIT: Oh.. and I also put in a small lipo monitor too.. works good so far

Wow, can't believe how quiet this thread has been. Everybody most be on vacation

Anyway, some good tips have been offered. Zippy makes a good budget pack that performs well and won't make you cry when you pile your heli into the ground. I had 4 of them for my HBK2. You charge them, head to a park, get a 4 flights in with no waiting, except for the motor to cool. I recently put the nose in ground and smashed up one of the Zippies. $17 down the drain. Meh, no biggie. It already had 40+ flights on it.

Another emerging pack is the Hyperion G3s. Boasting 4 times the lifetime and 5c charging (15 minutes or less for 2200). But you'll need a big charger for that.

The Cellpro line is nice. I have the 10s and the old 4s. The 10s is more than you need today, but would be a charger you could grow into. The 4s-multi will do what you need, but is limited. Its capped a 4 amps which it delivers to the packs via the node adapters. I find those are really only good for about 3.5 amps. So your charge time would be closer to 30 minutes.

Another charger to look at is the Icharger. There are a couple models. I'm not familar with them but have heard lots of good things about them.

OK here is an opinion for ya fender.

This Imax B6AC charger from hobbyking sucks!
http://www.hobbycity.com/hobbycity/...arger_1-6_Cells

I was given one by a club member to figure it out and show him how to use it. Thats when I found it wasnt a balance charger as us FMA guys think of a balance charger. You MUST charge through the discharge leads and balance with the balance tab both at the same time. And set the charger at an amp rate not a c rating. Works yes will the general public no different probably not. That said I wouldnt think twice about getting the FMA 4S multicharger. I loved the one I bought for another club member. I cant get one cause my old 4S charger just wont die.

Sorry about the IMAX rant just IMHO

Oh and as for batts the performance plus RC G2 packsare better in every way than the originals and the originals were dam great.

No Really I am the club President!!!

This is not a deficiency. In fact I would say its a better design than the FMA 4s and 4s multi. Why? The node wires on most packs are designed for balance charging of 1amp only. FMA packs can be run up to 4 amps on the node wires. But most others will get warm if charge it at 4 amps and cause the 4s to falsely detect issues with the pack. In addition, the IMAX goes to 5 amps. That isn't even possible on the FMA, nor would it be possible unless they also added charging through the discharge leads.
And set the charger at an amp rate not a c rating.
Another false advantage for the FMA products. The auto modes in the FMA 10s and 4s haven't worked correctly in almost 2 years. The AUTO mode will charge your packs at 3c to 5c in the first 10 minutes then it will under charge your packs and take longer than if you manually set the charge current.

The 4s-Multi can be made to work with current batteries. But you must create your charging map for each pack. Its actually quite a bit easier just to set the desired charge rate than build your own map.

Though I do like my FMA products, the advantages we all thought made the FMA products better than others are actually things that make thier products worse when compared to other mfg's products.

I have FMA 10S and probably it is the best charger by amount of votings, but I do not like there:
- noisy
- only two buttons to control all settings - not convinient and location is on a side. I'd prefer on top. I understand it lowers cost.
- cycling through presets not much convinient
- auto mode really fools, like Greg said.
- switching between charging 6S pack and two of less cells painful.
- tiny screen, again cycling to get to what you want to see

I believe, that if there was an option to correct these things and increase price, there will be customers, though FMA knows better.

I like customer support there - quickly and efficiently helped me when I had problems. I do not like how they ship - very slow at least to my place.

Second this. This is physics.

I like my MaxPro, I got it for free for beta testing.
Easy to setup parallel charging. Next one I probably get is problem iCharger thought.

Imax my friend have works great but voltages are way off if compare with a DMM.

Zaw,

Not to hijack the thread into a charger comparison.. but...

Interesting point. I guess I just took for granted that what it reported would be the actual voltages - kind of like taking for granted that when you ask someone what 1+1 is, for the most part, they'll all answer 2.

With the current technology of LIPO batteries I'm guessing that may not be a safe assumption.

How far off were you seeing with the Imax?
