Hi guys, I'm in the market for a new lipo charger.
I want one that is reliable & trouble free, suitable for a minimum of 6s batteries, uses a 12v power supply,(which I have already). Would prefer a charger that can charge two packs at the same time.
I currently have a Hyperion EOS0610iDUO2 charger, and am unhappy with it.
I charge 2s 40c lipos for trucks, 3c lipos for crawlers, and 6c 5000mah lipos for Helis.
I appreciate any and all advice, thanks, RobertM.

Why are you unhappey with the Hyperion charger?

I would suggest a 24 v power supply and go with a bigger charger.

You do understand that it will take about 2.5 hours to charge a 6s 5000mAh pack on that, right? Even if you can charge 4 at once, you would better off with a sungle port iCharger 206B charger. You could charge a 6s 5000mAh pack on at over 2C. That would give you a charged pack in less than 30min or a pair charged in parallel in less than an hour ... all for about $100 plus the cost of a power supply.

Best lipo battery charger

Wrongler, thanks for your advice. Also, I have had the Hyperion since I bought it new about 3years ago. I have been getting "output error" messages off and on since it was new. Now, that is all I get, it will not charge at all, on either charge port. I have cleaned and checked all connections, both input and output, including balancer connections. I get the error message with any and all balancer adapters I have. I never exceed 1c charging current. All I want to do is to safely charge my batteries. Thank you again, RobertM.

Talk to David at Progressive RC. I'd go with the PL6 or PL8, if you think you may ever need 7s or 8s. The I206 or I208 are also excellent chargers. They are more compact than the PL chargers. You cant go wrong with any of these, in my opinion. I'm running two PL8 and three I208 chargers on a 1500 Meanwell.

Don't forget about the iCharger 306B and 3010B. I recommend the PL6 and PL8 over the iCharger, but the iChargers are good and a bit less expensive than the FMA Driect/Revolectrix PowerLabs.

Thanks to all, looks like I'm leaning towards the PL6, or the PL8, at this point, RobertM.

From what I have been researching, PL8 over the PL6 due to the PL6 needing more voltage to achieve the amps.

The PL8 Power Supply calculator says you can charge 6s Battery at 40a with 24v and 50amp power supply.

The PL6 on the other hand requires 29.64v at 40a to achieve the same charge rate. I believe it tops out at around 32amp charge rate at 24v.

Since its very easy to pick up server power supplies and wire them in series to get 24v or even slightly higher with use of jumpers/resistors then the PL8 is the easiest way to go.

It's a little harder to get a 30v power supply to accommodate the PL6's full power.

Just something to think about. Read more than one thread out there with folks having trouble realizing the full potential of their PL6 chargers.

Most PS are only around 89% efficient. With that being said, a 50 amp PS is going to be running max to maintain a 40 amp charge rate, and probably a shortened life.

Exactly why I run 72a 900w server power supplies. A little loud, but super cheap and reliable.

The efficiency of the PS does not limit its rated output. A 50A PS will be capable of a 50A output. The thing to remember about PSs is they can be either power factor corrected (PFC) or not. This will have a significant impact on how powerful a generator you will need, if using a genny. It won't matter when using utility power from a typical wall socket. As an example, a non-PFC PS during each cycle of AC will temporarily store a significant amount of electrical energy in its circuitry (mostly in the transformer's iron core and copper wires). The peak power output to input ratio is typically 67% for non-PFC devices. This is why UPSs will show an input of 2000VA with an output of only 1340W (2000 * 0.67 = 1340) even though we all know a watt is volts * amps.

What you may have meant was the charger is only 89% eff. So a 1000W charger needs a minimum PS output of 1124W (1000/0.89 = 1124W). It is better to think in terms of watts to keep from getting confused about efficiency and power capability. For instance, a charger being feed by a PS with a maximum output amperage of 20 and voltage of 24V has an input power of 480W. If I wanted to fast charge a 3S pack (12.6V at full), I could charge it at about 34A (480 * 89% eff. = 427W, 427/12.6 = 34A) if the internal components of the charger and pack could handle the amperage.

You do bring up an important point about running the PS, or any electrical device for that matter, at maximum output. This will greatly shorten its life.

The Powerlab6 will do 860 watts (36 amps) on 24v. The online calculators are modest. Test results and details here http://www.rcgroups.com/forums/show...17#post20578347

As for running power supplies at less than 100%, there are two very important things to have to remember. First is that the duty cycle of LiPo charger about two thirds high current and one third low current. During the charge cycle, constant voltage stage tapers the charge current off as the pack becomes fully charged. This means the duty cycle of the power supply may only be 100% for a short duration of its work day. Even if we charge back to back (few people do) the power supply is taking a break for about 30% of the time.

Secondly, if you are buying used supplies on ebay, it costs very very little to have a spare or two. Very little.
