I have a couple of the Hyperion's and have never updated them and wondering if there is even an update for them. Seems that all of the newer sizes of lipo's come with odd numbered capacities like 1350 instead of either 1300, or 1400. Being OCD makes me want to put the right amount of charge data into the charger. Just wondering if an update would do the trick for me.

I think most chargers only go up in 100mAh increments. I could be wrong of course. +/-50mAh isn't going to make any difference when doing a 1C charge anyway because the packs actual capacity can vary that much or more.

60% of the time, it works every time!

I have always rounded mine to the nearest 500 just to keep the amount of programs lower. I figure I am smarter than the charger (just not as fast) A few MA here or there will not matter. The label really doesn't matter it is the current programed that matters.

But that won't help your OCD

Well I have had these chargers for a few years now and figured the newer ones out there would get you closer to the stated capacity. As far as the OCD goes got to harness that thing. lol

Never fear, that setting is not a limit as to how "full" the battery will be charged. It determines the speed at which it will charge. A 2200mA battery charged at 2.2 amps (1C) will take a certain time to fully charge. The exact same battery in the same conditions charged at 4.4 amps (2C) will finish in approximately half the time. (Not really true, but a useful approximation.) The end state of either charge will be the same in either case. So, your 50mA difference that concerned you might make a few minutes difference in the charging time. The battery will be "fully" charged, at least to the same amount, in either case.

The figure/label of lets say 2200 on a Hyperion charger is nothing more than the name of the program i.e. program 1-20. This applied to all but the first 10a chargers running the first SW. There is a person by the name of Cam on here that used to write the manuals for Hyperion. He has since moved on but there may be something in his old posts. On the first SW the charge rate could not be programed to go above a 1C charge for a given battery. We simply lied to the charger and told it the battery was 4400 vs the actual of 2200.

Since batteries now have the ability to be charged up to 5C, they removed that from the restrictions. Now in the SW, the 2200 that is programed in is the name of the program. The charger uses the charge rate programed in to establish the rate and 4.2 as the cutoff. Those 2 items are the ones that control the charge of your batteries.

I have my chargers programed for 1000, 1500, 2000, 2500,- 5000 and a 3C charge for each. I skip some steps if I don't have a battery in that range/cell count. So if I am charging a 2200 I have the ability to go up or down depending on what is happing at the point in time. If I am in a hurry I may put that battery on a 2500 program or a 2000 program. I know the 2000 will charge the battery at 6.0 or the 2500 will charge it at 7.5. Remember the 2000 is the program name, all the other information programed under that name is the important items to consider!!!

This only applies to Hyperion. That is all I have run over the last 7 years.

A bit confusing this, could you explain more? what do you mean 6.0 and 7.5?

I charge at 3C. Say for instance. I have 6s packs of 2200 3300 and 5000. I have programed 2500-7.5a, 3000-9a, and 5000-15a. Now I have choices when I hook up a battery. Since I know what I have the charger set to as far as charge rate is concerned i.e. 7.5a-9a-or 15a. If I am flying a 500 and a 450 I can select the 3000 program and charge both batteries one a littler fast and one slightly slow. I know the charger is 2 channels but the other channel may be used on something else. I actually have a large DUO and a smaller 20a single in the same case.

The point here is what we program in here for battery capacity is not being consumed in the charger. It is only the program name, The data programed below that point is what the charger used to set up the charge parameters.

I use my method to keep from having to change to another program all the time. IF it is close I use it knowing the rate I have for each

Yes it is! If you program 2200mah charge rate, that's the current at which the pack will be charged, 2.2A.

The OP is not talking about the names/numbers you give to your preset's, he means the actual charge current, in his case he wants 1350mah (1.35A charge) but most chargers only go up in 100mah steps so he is stuck with either 1300mah or 1400mah.

Rpat, there are still plenty on packs out there at either 1300 or 1400mah, Turnigy do 1300mah and Optipower do 1400mah and iv'e only done a quick search. Or could you stick a 1300mah lable over the 1350mah lable?

yea it is something that has bugged me for awhile and the two duo's that I have are great chargers but kind of thought that they would have upped the programing on them by now being that this is kind of a precision hobby with OCD people in it like me.

I hope that you don't get your self confused one day by charging with different settings that what should be in the charger to begin with. Good luck with that one. To me it is too easy to scroll through the list and pick the right setting for what you want to do. Of course OCD is talking here.

When the manufacturers say 1C charge there will be an acceptable percentage deviation, my guess is +/-10%. 50mah difference to a 1350mah pack is 3.8%.

For the most part, the capacity number is irrelevant when charging.

The charger monitors both pack and individual cell voltage to determine state of charge. It will keep track of the overall amount of energy put back into the pack, but will typically use that value as the basis for a safety cutoff (and you can also program a maximum time on charge as a secondary limit).

If your pack says it is a 1350 mah pack, that is generally only a minimum rating, not an absolute rating.

The 1350 number is also known as the 1C rating. You can expect to have the fully charged pack to deliver 1350 ma constantly for one hour before it is fully discharged. But you can get 2700 ma out of it for a 1/2 hour. Or 675 ma for two hours.

A 1000 mah, 50C discharge rated pack will deliver 50 amps continuously till discharged without substantial heating or excessive terminal voltage drop. But at 50 amps, it will be discharged in a hurry.

As for charging, it is rare these days to be limited to a 1C charge rate.

You can charge at a lower than 1C rate, the battery will take longer to charge, but the charger will run until the battery is full. You can also charge at greater than the 1C rate, the battery will still be fully charged by the charger, but charging time will be reduced. 5C (or higher) charge rates are not uncommon today.

By setting your charge rate at exactly the 1C rating, all you are guaranteeing is that you will have to wait about an hour to charge the pack if it is fully discharged.

The charger, given the correct number of cells, will charge your battery fully, whether you charge at 600 ma or 6000 ma.

Don't exceed the maximum charge rate, you'll be fine.

But having to charge at exactly the 1C rated current has no basis in reality. If you're going to be OCD, find something more important about which to obsess.

Wrong... you can never get 2700mah out of a 1350mah battery. And you will never get a full battery ratings worth of power out of it. How fast you discharge has nothing to do with the battery's capacity.

I think he meant discharging a 1350mah pack at 2700ma (2.7A) would be discharged fully in 30 minutes.

Charging and discharging has everything to do with the batteries capacity! That's what the C stands for!

I have the 308 duo and have the capacity set to undefined or something like that. I just put at what amperage I want to charge at and that's all. On the duo, the only reason for the capacity is to shut down the charger if you go over that number. Big pain when you want to parallel charge then just charge a single pack.

You can charge/discharge at any rate you choose (within the design limits). The battery can only hold a given total amount of energy.

I know all about C ratings... lies all.

Splatter -- MUST READ MY POST CAREFULLY. I said:

2700 ma, over the course of a half-hour. I didn't say 2700 mah for a half-hour.

Note that you can suck AMPS out of the battery, has little or nothing to do with its energy density (mah).

2700 ma from the battery over the course of a 1/2 hour is indeed easily obtained from a 1350 mah pack. 2700 x 0.5 = 1350. Just as you can get 675 ma for two hours.

2700 milliamps x 0.5 hour yields 1350 milliamp-hours.
675 milliamps x two hours yields 1350 milliamp-hours.
