BlueLipo Review

I have been a fan of the Hobby City Zippy/Turnigy/Flightmax line for the past 2 years. This is no longer so. I've finally found a vendor in the USA that carries Lipos at a reasonable price which perform to my expectations.  The BlueLipo line that is currently carried by HobbyPartz,Xheli and to some extent Nitroplanes and NitroRCX has not dissapointed me.  I have never been much of a fan of the high dollar Lipos that cost $50-$80 for a 3S 2200mAh pack! I"m a "bang for the buck" kind of person. Those packs are high quality, often come with a crash policy, can advertise a higher charge rate (if your charger can handle it)  but most pilots won't know the difference between that and a $20 3S 2200mAh 30C BlueLipo Pack. Some will say the high $$ packs last twice as long (number of cycles) but my opinion is I'd rather have 2x or 3x the number of packs and cycle them less and have more flights in a day without having to field charge.   I also don't wish to have that much invested in a battery in the event of total loss, stolen or battery failure that I induce myself.  On all my 3S 2200mAh or larger batteries, I switch over to a Deans Ultra plug (just what I"ve standardized on) but the BlueLipo packs come with a 4mm Plastic cased Bullet connector.   Bullet connectors are generally easier to solder on to a wire than Deans which requires heat shrinking and clamping to the wires and conector to make sure they don't move. The smaller BlueLipo packs (for foamies, micro helis etc) will come with typical 2 pin JST connectors. The batteries come with a balance port with the very common JST-XH type connector on it.  

I charged, then cycled the batteries times then measured the Internal resistance on the packs using a Junsi 106B+ iCharger and found that the total IR was on par if not slighly better than my Flightmax or Zippy batteries of the same discharge rate, cell capacity and number of cells. I then procedded to break-in my lipos doing simple short hover flights. After the break-in, the IR was still good.  I had a friend try out the 6S 5000mAh 25C pack on his Trex 600 and Hyperion charger and it measured a slightly lower IR (lower is better) than his Zippy-H pack he has been using.  He reported good performance even towards the last half of the discharge.   I did some flight tests on 2200mAh 3S 25C and 2200mAh 6S 20C packs in my 450 and 500 helicopters.  Both hover duration as well as some aerobatics (FFF, flips, loops, tic tocs, punch outs etc) and found the BlueLipo performed just as well as the Zippy/Flightmax/Turnigy batteries I had recieved a few months earlier (all with less than 30 flights).

The nice thing about these batteries is that Xheli offers $4.95 shipping on parts only.
Hobbypartz also charges only $4.95 for shipping. So unlike ordering from Hong Kong, you are getting domestic shipping and at a great price for Lipos!.

About C rating:
Often a confusion for many people.
C rating typically refers to the maximum discharge rate.  A 20C 2200mAh pack can discharge at 44A max (2.2A x 20 = 44a).  But what is not express is typically the higher C packs will have a lower Internal Resistance. That internal resistance is directly proportional to the internal voltage drop of the battery pack while under load.  Cheap ebay battery packs are often notorious for having a very high IR (Mystery brand for example). This will result in motor bog af full pitch punch outs and tic tocs where the RPMS sags after your first TIC).

Generally, here is my advice on battery purchases:
20C = Beginner Novice hovering and basic non-aggressive Sport flying
25C = Aggressive sport flying to mild 3D aerobatics
30C+ = 3D aerobatics involving continuous rapid changes in pitch or cyclic

I advise Novices and beginners to purchase multiple 20C packs so they can get more flying in. They should learn on those 20C packs and be putting 50+ flights on them before looking to upgrade. Later, they can use those cheaper 20C packs as warm up flights or test flights before using up other packs for the day's flying.
