Because I'm running one 3cell LiPo at a time, and charging one 3cell lipo at a time, my 12volt 760watt 64amp Prototype Common Sense Power Supply I bought for about 125.oo can charge my 3cell 5000mah 40c Thunder Power Pro Race LiPo to 100% charge in 10:34 seconds at a 30amp charge rate. And that's with only a 12volt power supply. This charger is the most awesome, accurate Balance charger I've ever seen, read about or experienced in my life. I'm a very happy young man.

ah yes, but with all your research you missed the first thing that stuck out to me in the owners manual: 12v 500w LIMIT, 24v 1000w limit.

So even though you have a 760w power supply, you can only use 500w of it. You need a 24v power supply to use the charger to it's rated capacity.

Not that anybody requires that (yet), but it's good info to put out there for those that do want to buy this charger and use it to it's full potential.

Hi paralysed,
My goal when buying this charger was to charge my 3cell lipo at the full 30amps. Because charging a 3cell lipo at 30amps does not require the full 1000 watts of this charger, I bought the Power Supply I found to be suitable for my specific needs. If I ever need to charge, say a 6cell lipo at 30 amps, I will then need to buy a new Power Supply, At this time, I race my Hyper 9E 1/8th scale buggy with one 3cell lipo and it's quite perfect for me. As I hope you can now see, no detail was missed. I have no need to spend the extra money for a power supply with a capacity I'm not now fully utilizing, thus I bought the power supply most fitting to my specific needs. Now, if the charger need a 24v power supply in order to charge my 3cell lipo at the full 30amps, then I most certainly would have bought a 24volt power supply. I do thank you for clarifying your thoughts regarding the use of the full potential of the charger, but for my specific needs, it's more about utilizing the full potential of my battery. My battery is rated at 6c charge rate. 5000mah. That's 30amp charging, and ten minute charging is awe so sweet :) with my 12volt power supply. But don't get me wrong, I do understand your point, as well; I hope you understand that I have 100% fulfilled my specific charging and power supply needs.

I've not yet measured the temperature. Though I can say, during and just after a ten minute 30amp quick charge, the battery is not even warm to the touch. I believe this is why I did not measure the temperature, it was only a few degrees above room temperature. If the lipo was very warm, or hot; I can assure you I would measure that tempurature most promptly. I will measure my next quick charge temperature, and post my findings. I should have this data by the end of this weekend. Have a great day :)

My Thunder Power 3cell Lipo 5000mah 40c battery consistantly reads exactly 84degrees after a ten minute, 30 amp quick charge. Room temperature was a few degrees bellow 84degrees. The battery pack is about 16 months old, and apx 100 cycles of use. I experience zero difference in power or run time, if I charge the battery at 1c = 5amps, or 6c = 30amps. Same power, same run time. Much quicker charge. Thunder Power said the 30amp quick charge reduces the life of their batteries, zero. Others say I may or will reduce the life of my lipos with 30amp fast charges. I opt for the quick charge, because I very much like having my battery fully charged in less than ten minutes.
