I got a 4s 5000 mah battery. I dujno much about charger beside that bigger better faster in general.Could someone explein me with some detail like time of charge. i would get for each of those charger with the battery i mentioned above.

Its all about charger output power and what alipo requires for a given charge. A 4S charging at 1C will need 16.8v x 5a = 84watts. The currently sold 0606i is a 50watt output charger (AC) and will reduce the charge current to stay under its power limit, so with it you would get 50watts/16.8v = ~3amps. Thats all this charger can do because of its output power.

The new 0720 on the other hand would be able to charge this at 1C since its output power is 90watts. WIth only 90watts though, it won't do more like the 5C charge they mention - at least for your 5000mah 4S - a 5C charge rate for that is 25amps and would require 420watts, way beyond what charger is rated. There are smaller lipos though where you could take advantage of higher C charge rates if the lipo permits.

Lipo charging is a 2 step process - CC/CV - constant current followed by constant voltage periods. The CC is the charge rate and it charges the cells to the max cell voltage of 4.2v/cell. When the cells reach max voltage, the charger switches to the CV stage where it holds the cells at constant voltage and allows the cells to top off. You will see charge current decreasing during the stage, thats normal. It will go down toward zero current, how close it gets depends on the charge rate that was used. The charger terminates when it reaches this lowest current in the CV stage.

There is no set charge time, it depends on how deeply the lipo's been discharged, but folks have noticed, that at 1C for an 80% capacity discharge, it takes about an hr for both steps to complete. Charging at higher C rates reduces this time. Using the FAST lipo mode some chargers offer also reduces charge time since the charger in FAST lipo charge mode eliminates the CV step which is typically the longer time wise of the two steps.


Of these 2, the 0720 would be the better since it will allow you to do a full 1C charge on your 5000mag 4S lipos.

hyperion makes the "EOS 0720i NET3 AD" you mentioned above but if you dont mind getting a power supply they also make the EOS 0720i NET3 ....the dc only version. and that one will do 250 watts x1 output that would get you close to 3c charging with a 4s 5000 16.8 volts x 15 amps 252 watts....... that would charge one battery at a time fast, but i would just get the EOS 0615i DUO3 180 watts x 2! that way you can charge 2 battery's at once and still pretty fast and even it its a little slower that the EOS 0720i NET3 dc version at least when its done charging you will have 2 charged battery's not just 1.


most powerful chargers require a power supply...a big one

if i had to choise between the two above the EOS 0720i NET3-AD all the way


if your 4s 5000 was run all the way down the EOS0606i would take like 90min the EOS0720iNET3 ad without a power supply just under 1 hour and the EOS0720iNET3 with a power supply maybe 40 min

Allright, The EOS 0720i NET3 seem a good idea also. But now Power supply wise. Would i be ok with this one

or this maybe

http://www.amainhobbies.com/product_...C-Power-Supply

Either supply will run the 0720 DC charger, but the 1st won't run the charger at full power. Chargers have some inefficiency or loss (takes something to 'run' the charger and energy lost as heat). Generally its considered that you need 20% more wattage than the charger is rated for, so the 250watt charger would need 300watts to run at full power delivering 250watts.

Your 1st link wouldn't, but the 2nd linked supply would run the charger at its full capacity.


You can use up a lot of power with higher than 1C rate charging. If your 4S allows 5C charging, there are other chargers that can enable that. As mentioned above, the 0720 DC charger would limit you to right at 3C. Hyperion is re-vamping their lineup supposedly sometime in July with more charger output power in a few new models. There will be a 1420 DC powered charger with 500watt output iirc.

Here is a resume of what i finnaly bought.

1 x HP-EOS12-SEN Hyperion Battery Charger Temperature Sensor $8.99
1 x OFN92134 OFNA Supreme Power 12V/30A DC Power Supply $99.99
1 x HP-EOS720I-V3 Hyperion EOS 0720i-Net3 Li/NiMH/A123 Balancing Charger (7S/20A/250W) $169.99
1 x SUM5250CM4 SMC "C-MAX" 4S Hard Case Li-Poly Battery w/Deans Connector 50C (14.8V/5200mAh) $179.99

dunno if that can hold 5c charge rate

Edit: DO i need any adapter for my charger to charge this battery? I so can you show me one on amainhobby pls?

That lipo uses what is known as a JST-XH type balance connector. I believe that Hyperion supplies that and the Hyperion type balance adapters with a new charger. Their ad for that charger shows only the Hyperion balance adapter board. This is the one you would need -

When I bought my Hyperion chargers (pair of 0610iNet) iboth came with just the Hyperion type balance adapter. One of Hyperions big distributors posts and RCGroups and says they now come with two boards (Hyperion and teh XH type which is the one that SMC will use). You could call and ask. The adapter boards will share a cable connecting them to the charger.

Read the instructions for the SMC lipo and follow them, their lipos seem to be a little diff from a maintenance viewpoint. Nice setup, enjoy!

Any know who I need to contact to get my hyperion worked on or serviced....

Calll All E RC - they're a hyperion Dealer - 480-456-4300. They'll be able to tell you what you need to do.

Thanks Duster, I'll give them a call.

Hi Duster!

I recently purchased a Hyperion EOSO720iNET3 AD charger, but, being new to the LiPo technology, I'm having some problems understanding the so-called 'user manual' that came with the charger. Is there any source for some connection diagrams, illustrations, photos that show how to make the connections for this charger? It's not clear to me just what the short wire set and alligator clips are for, nor where to connect them; also, do the DC/battery inputs go to the red/black connectors on the top right side of the charger (as viewed from the top/front)?

Any help would be appreciated.

RSVP/thanks,

Dave P.

The long red/black wire attached to the charger are for DC power input. These have 4mm bullet connectors that typically plug into female bullet connectors on a DC power supply. If you'll look at one handle of the alligator clamp, you'll see a female bullet in one of the handles. The alligator clamps plug into the DC input leads so you can connect to an auto type battery or gel cell using the alligator clamps. If you're going to run AC, you will not use these or the red/black DC input cable. You can put it under the charge like shown here so its out of the way -

The red/black short wire set is for connecting your battery - the bullet ends goes into the front of the charger, lower right as you guessed. Hyperion does not solder on a connector and leaves that to you so you can match the main power connector on your batteries. I leave these plugged in on my old 0610i Hyperion charger, there's no need to be removing these constantly, I just unplug the battery. Whatever battery connector you use will be a female end so there's no danger of a short when the charger is on prior to connecting a battery.

There's not really any illustrations besides that shown on the Charger page that I'm aware of, its really pretty straight forward. The manual will tell you how to connect a lipo to the charger, unless Hyperion has changed, there is an order to follow - connect the main power lead and then balance connector, reverse the order when charge is finished.

The two balance boards or balance adapters are for different type of balance connectoins. One of for the type balance conn used by Hyperion lipos and teh other is for the JST-XH balance connector (also called Alighn type or Eflite type). Use the one that matches your lipo and plug it in as instructed in the appropriate cell count slot.

You'll need to follow along in the manual and do some initial setup and once thru, you're ready to charge your first battery.


LMK if you have questions.

Hi Duster!

Many thanks for the quick response and help!! I'll see if I can make some progress as soon as my first battery drops out of the sky.

Thanks again,

Dave P.

You're welcome, the whold thing should make a little more sense when you have lipo in front of you. And just in case no ones told you, lipos are delivered partialy charged and you do need to fully charge them before using.
