I will be getting some Hyperion battery for my 51'' AJ slick. the reason I am getting them is because they can charge in 10-12 min. What charger from them do I need to do this, the maximum amount of money I can spent On a charger is $150.

Number of cell and capacity would help.

A 4S 3200 charged at 5C would be 16.8 volts X 16 amps. = 269 watts.

iCharger 208 is one to look at. You will need a 350 watt power supply also .

http://progressiverc.com/


and epbuddy.com are places to check

Charge times will be closer to 15-18 min. for a full balanced charge at 5C.

Fine but not for $150 . A Hyp. 720i Net 3 is 250 watts and more than $150 and you still have to have a power supply . The 720i will need 17 volts for max. output while the iccharger can do 250 with 12 volts input. Either can use 24 volts power supply but they are more expensive unless you go the duel server power supply route and do it yourself type. Looks like you need to do some research.

What specific charger do you suggest? I do not want to spent over $150 for a charger, I have never done fast charging before and am clueless as to what to get. I have always slow charged my batteries, but want to start fast charging now. If you have any suggestion please let me know, thanks.

suggestion would be to buy two batteries and charge at 2c

Fly one pack while the other is charging.

Shoot the shite with the fella's between flights while the second pack is topping off on the charger. When its done, the first pack has cooled down enough to be charged...so charge it while you fly the second pack.

fly, charge, repeat.

Better for you and better for your batteries.

From what I gather, you will be flying one pack for now...and want very fast turnaround so you can fly more.

Yeah, get more than one battery. Get two or three and your power supply/charger requirements will be lessened.

the charger you would need has to have at least 218watts capabilities.

your hyperion 4s 2600mAH packs breakdown to
4s = 16.8v fully charged voltage
2600mAH is 2.6AMPS
Multiply the amps times the Charge "C" rating of 5 and you get 13amps charge rate
Watts is the product of max amps times the voltage
W=13A x 16.8
W=218.4

So whatever charger you get needs to be rated at 218 watts or HIGHER and the power supply you purchase must also be able to deliver 218watts or better at 12v.

If you are resourcefull, you can get a decent PC power supply and convert it with banana jacks to supply a charger like the Hyperion EOS 720 i-Net III.

Cheapest sub-$150 charger that will charge a 4S 2600mAh lipoly at 5C that I am aware of is this one. I have one and it works really well after I modified it to improve reliability. Hard to recommend, however, due to sketchy design.

Cheapest charger that I would recommend for your purposes is the iCharger 206B available from epbuddy.com and progressiverc.com (as Charles quoted in post #2 above).

Any of the listed chargers can be powered by a cheap ($20 or less) converted server supply and meet your power requirements.

I agree with the iCharger 206B and it's within your budget.

It's nice and small too if you're taking it to the field.

This line is worth paying attention to with regards to the input voltage.

Maximum charge power capacity : 300W (@ input voltage > 18V)

I wonder what its max wattage rating is with a standard pc power supply putting out 12v

At 12V, 220 watts. About 270 watts when used with popular the iCharger 15V PSU.

I am thinking about going with this charger, HYPERION EOS720I NET 3 AC/DC BALANCE CHARGER. It fits my price range. My question is will my old power supply from an computer at 12 volt be enough for this charger?

"old power supply from an computer" is not enough information to answer that.

As Charles said, it won't run it at full power due to being 12V. Whether the PS can keep up with the charger's reduced maximum at 12V depends on how many amps the PS can reliably put out on the 12V output.

The power supply says 225watt maximum, will this be enough to charge my Hyperion batteries in 10-12 min.? If not I may have to look and see what else I can find.

Probably not - but not enough info to be sure. Those watts are distributed over several outputs. What does it claim to put out on the +12V?
