Tattu R-Line Square 4S 1300mAh 95C XT60

Less sag. More amps and... it's square!

Same great battery, new form factor. Keeping the battery mass centered around your multi's center of gravity will help you achieve a more locked in feel, as the quad is not having to expend extra energy trying to whip around mass that is further away from the point of balance. 

If you are looking for a strong battery to power your latest creation the Tattu R-Line will work well for you. Increased energy density, lower internal resistance and higher discharge rates means longer flight times, faster acceleration and higher top end speeds. The Tattu R-Line have been designed to survive the rigors of FPV racing, which means, putting this battery into anything less than a tricked out, tuned up, amp sucking, race quad is going to be a walk in the park.
