HobbyKing Multistar High Capacity 4S 5200mAh Multi-Rotor Lipo Pack

I bought this battery for my (fixed wing) Volantex Ranger 757-3. It works great. I plan on buying a second one and hooking them together for longer range missions. I already do that with my 3s batteries.Follow up: I have two of these batteries now and they work very well. I flew 8.5 miles total one evening and still landed with more than a 50% charge. A great battery for long distance cruising.

Great quality, very light for the capacity, flies good so far, doesn't heat up. Great for 450-size quads, too low C rating for anything larger. Charge time is about 2h with b6ac, consider using more powerful charger with these high-capacity batteries if you fly a lot. I'm thinking of getting Multistar 4000mAh batteries for lighter quad and faster charge time.

So far it is holding within .01 on voltage of all 4 after 10 discharges and 11 charges, have been charging at 1c level, lasts for a good 32 minutes on my quad with 2213's x4 and cleanflight.

Sent a faulty product with several breaks in the wire and HobbyKing will not take the product back. Beware they do not stand behind their products.

Please note that this is only a 10C battery, but I only need 50A burst on my aircraft, so the 52A it's rated for will do fine.I tested it at 70A and voltage sagged only to 15V while offering a couple of extra amps on the same motor, as other batteries, which was unexpected.This battery is almost the same size as the 4200 lumenier, so it's compact, but of course it weighs more, and that's ok. It's however much smaller and lighter than the smaller capacity HRB 5000mAh, so I'm happy with it.For comparison, here are other 4S batteries I tested:Lumenier 4200mAh 35C 387g - smallestMultistar High Capacity 4S 5200mAh 10C 437g - 2nd smallestHRB 4S 14.8v 5000mAh 50C 520g(!) - bigger and much heavier than MultistarTattu LiPo Battery Pack 6750mAh 14.8V 25C 560g - biggest

Excellent power and capacity for my Wing. Balance charges at 1C just fine, all cells were within good range after use. Priced just right for the plane it went in. Very pleased with purchase, and would not hesitate to purchase another.

No impressed. under performs.

About to return for refund... the battery I got has a bad Cell 1 it seems.I am on my 4th charge/flight and if after this flight it remains damaged I am going to return.Yes, I use a balance charger; won't allow OC.No, I did not over drain the battery; I use an alarm set at 3.3v trigger.Longest flight so far is 20 minutes on an SK450; Multistar ESC and Motors. (stock)==Update.. after about the 5th cycle it seems to be draining at the same rate as the other cells; I will keep an eye on it.I also changed the alarm to go off at a 3.6v trigger as other have advised for this battery.

Disgraceful. Battery would not charge and return refused
