Gens ace 520mah 2s and 3s Lipo battery for MINI FPV Racing Drones

Tattu GENS ACE 520mah 30C / 60C 2s 7.4v & 3s 11.1V are one of the best quality LIPO that we can buy for mini drones between 70-120 size. GENS ACE also is manufacturing well knowed batteries Tattu which are one of the best on the market like SLS or Bonka. These high class lipo are not a joke, it provides the best power I ever seen, if you never try it then do it & you will never back to old ones.

Discharge rate & Capacity & Cycles

If Gens Ace / Tattu wrote down that battery got 30/60C then this nuber are true, at some chinese or turnigy batteries we can find 50-100C but in most acses these batteries can’t even reach half of this rate … . OK, let’s do some math , to know what is dicharge rate we have to mutiple capacity 520 by discharge rate 30C and the result is  15 600mA

Continous discharge rate is 520mah(0,52A) x 30C = 15600mA ( 15,6A ) , burst is 60c so 31,2A  which is Super score because mini drones in most cases can’t take more than 25A .

These batteries are BEAST, I been able to pump in 565mah ! ( from 3.2V to 4.2 ) . Ofcourse this is nothing new because usually in these batteries capacity is higher than showed on label.

Cycle life span should be not less than 200 if you will charge these batteries under 1C , best one will 0,5C.

Size and weight

Weight for 2s GENS ACE 520mah is only 28g which is great score compare to capacity and discharge rate, while 3s GENS ACE 520mah is literally a fat cow ( 44grams ).

Size and weight

Size for 2s is 24x15x45mm & for 3s is 24x22x45mm . Here you can see a size difference:

Usage & flight test

2s GENS ACE 520mah works delicious, drone has good punch but still BOLT battery is mouch powerful to go due to Super high discharge rate 65-130C.

3s GENS ACE 520mah has really great punch BUT is way too heavy. 44grams is too much for small drones so most of extra energy is used to hover and just a bit for a bit more noticable fun. So best choice will be 3s 300mah and at least 45/90c but good luck to find it … . If you still want more power today then buy BOLD batteries from turnigy with Unholy C rating 65-130.

Price

2s and 3s GENS ACE 520mah have different price, if you have interesting in 520mAh 2s lipo and 520mAh 3s lipo battery, you can chick it: http://www.genstattu.com.  so as you see price is low compare to quality.
