Default Universal Battery charger ?

Electric noob here
With that in mind I am looking for a "universal" type charger for aircraft
system that will go into 5-8ft' WS planes. Also I wouldn't mind building
one from components if someone has a superior design. I know I am
asking a rather vague question but all response is welcome as I learned
a long time ago that the wrong question is the one that does not get asked.
Thanks All!

Chargers generally stay on the ground, they don't go in aircraft. We charge the batteries, put them in the planes and then go flying.

So can we start from the basics ? What exactly do you want to charge ? What source of power do you expect to drive it from ? Are you really expecting something that flies in the plane ?

I'm assuming you need to charge batteries that will be installed IN your model.

I've designed and built a number of LiPo and A123 battery chargers over the years. The three last chargers could charge and balance a 6S2P A123 battery pack at a 10 Amp charging rate. These chargers were good for about 400 watts charging output. It was switch selectable between 4, 5 and 6 A123's. The microcontroller monitored voltage to make certain the cell count was right before start of the charge cycle. The charger could charge 4, 5, and 6 cell A123 batteries, and nothing else. The microcontroller used also displayed total time, amp hours, battery voltage, lead acid battery voltage, and so on. I used these scratch built chargers for several years.

Then the high powered Cellpro chargers came out. That said, this charger was far less capable than my two Cellpro Powerlab 8 chargers. That high powered Cellpro '8 charger is far above anything I built, and it was considerably less expensive than scratch building!

Default Forgive the wording

Yes, the batteries that get charged on the gound
Guess what I meant to ask was a charger that will do multiple duty.
I realize I'll wind up with several chargers but would like to minimize the #.
I like ALL flying models so 14" wingspan or 14 foot I am
Crazy enough to try almost anything once
And you just confirmed my suspicion Kyle- prebuilt it is,
Thanks

Any reasonable quality LiPo charger will also charge other battery types, so no need to get more than one. the Cellpro and iCharger ranges of chargers are very good if your budget will stretch.

Too many to count. A really good one that can charge any Lithium, NiCd, NiMh, Lead acid up to about 20 volts @ 20 AH at high rates is an iCharger 106b for around $90. As with most of them you will need a Dc power source like a DC power Supply or rather large 12 volt battery. Or just your your vehicle cigarette lighter port.

Here you go George pick up a couple of these chargers, they are inexpensive but work great.they will Charge everything that needs to be charged If you need a power supply, You can make one fron a old comp. power supply.

Just a note here.

I've got two of those Cellpro Powerlab 8 chargers. These chargers can pull over 50 Amps out your 12 Volt DC power source. That's what it takes to recharge a 12S2P A123 battery pack as a 6S4P, charging at 30 Amps. And, pulling 50 Amps out of a 120 Ampere Hour Deep Cycle lead acid battery will kill that lead acid battery in only a month or three. I was getting two or three flights per charge out of that 120 Amp Hour battery with the 12S2P battery pack. And, two months later, that dropped to one flight per charge.

It looks like these lead acid batteries are only good for 15-20 Amp discharge, if you expect any life out of them. Those lead acid batteries worked OK when recharging a 6S2P A123 battery pack at about 10 Amps.

Other web sites show that a top of the line substation class 120 Amp Hour deep cycle battery is only good for 30 Amps maximum. And that will discharge that lead acid battery in one hour. That's pretty much what I found. And, that's why my field DC power supply is now a gasoline powered alternator.

As for the Cellpro Powerlab 8 charger, this unit can charge just about any battery chemistry out there. And should new chemistries become available in the future, the Cellopro charger software can be field upgraded from files available from Cellpro.

A Little more info on converting a comp power supply and My Power supply conversion I cleaned up all those extra wires since that pic was taken

Now I have a use for all those "extra" tv's and computers LOL.
I do have a really good power supply schematic somewhere too, when
I find I will post. And yes I saw that thread kyle, cool, I was planning on bolting my 8500 wattt generator in my p-up
After more research I am going with the powerlab 8 , when and if finances allow

Got a good deal on Uni-tester at http://www.mrpositive.co.nz/ . This universal tester will test the condition and charge state of almost any type of battery and battery chemistry.
