Question on Hyperion/Lipos charging Amps?
I have a hyperion charger and Im charging a max amps 6000 mah 3's battery. I have the charger set at 6000 mah and 3's lipo with the built in balancer connected...to be honest i have just started paying attention to the charging amps, this being said when all is connected as stated above it begins charging at 4.34-4.35 charging amps. I think it should be charging at 6 amps with my settings at 6000 mah. I also have a 6000 mah 2's lipo and when I charge it with the same settings except switched to 2's it charges at 6 amps like It should. Is there something wrong with my 3's lipo when its charging or does it just charge at a different amp because its 11.1v lipo.

Ok im keeping a close eye on this charge and the charging amps has dropped to 4.24...could it be possible there is something wrong with my battery pack. any help would be greatly appreciated.

How much charge is in the pack when you start charging?????
I'm not familiar with the hyperion chargers but I know many of the lipo chargers start to reduce amperage while charging as they approach the cut off voltage based on how many size of the pack. It could be that your pack is still relatively "full" so it is using less amperage to make sure it doesn't overcharge the battery.

As Robbie stated most lipo chargers will start lowering the amps after the pack reaches 4.2 volts per cell until the pack hold that voltage with no charge. The other way of charging is to cut the amps off when the battery reaches 4.2V per cell and back on when it goes under voltage. Both work about the same.
I think you are experiencing something different. Some chargers will not charge a 3 cell/11.1 pack at the same amps as they will a 1 or 2 cell. It have to trade off some amps to make up the voltage. The only real - affect you will see is increased charge time.

It was pretty dead. I am pretty sure the voltage cut-off was ready to kick in. It has been charging over 50 min right now. Edit...the final charge was 12.65 volts. The charger did keep dropping amps until the peak was reached and took 85 mininutes to complete. I read the directions and it did'nt say anything about 3's 11.1 volt batteries charging at a lower amp rating than a 2's battery. it says it will charge at
1C rate= 6000 mah = 6.0 amps. and if it were more than 6000 mah it would just charge at the 6000 mah setting (I'm assuming at 6.0 amps) but it would just take longer to charge. I dunno. The charger is a Hyperion EOS 0606i AC/DC. Maybe somebody knows more, I have to say the instructions a vague to say the least.

A lipo that has been cutoff should take about an hour to charge, maybe a bit more.

Are the figures you are coming up with using from the built in AC power supply?
If so this might be the reason you are seeing 6 amp charge rates with the 2S and only 4.3 amps with the 3s. From memory the built in power supply is only capable of 50 watts. Try using a external power supply capable of 10 amps or more with the 3S and you should see different results.

Super_Roo is correct. The charger you have has a maximum output of 50 watts. I was going to get that same charger but decided not to because of the 50 watt limit. The charger is fine and will work but like Stallard said above, the only drawback is an increased charging time.
Best regards,

thanks for clearing that up guys, i had no idea of those limitations on the ac/dc. I was using a wall unit the whole time and I was very confused. thanks for schooling me guys...lol.
