Gens ace2S Lipo Battery Redline Series 5100mAh 7.6V 130C 2S2P HardCase HV Shorty Lipo Battery

I like that these batteries come with the bullet plugs. I used an old set of 2s battery wires, swapped to the included bullets and the qx1 or whatever ginormous connector. I use shorty packs as a weight tuning aid in most of my race chassis. These fit the bill well.

These packs are more powerful and lighter than the equivalent standard lipo packs. They also can be charged at 25 amps (if you have a charger that can do it). This pack in my ET410.2, is insane.. it has so much power, and a little extra top speed with the voltage.. I was easily keeping up with 8th scale buggies on 4S.. I liked it so much, I bought a second one.

Need a better battery than the basic gems ace. This is the ticket! All the redline series is amazing! Reliable and powerful!

I like the size for Drag Racing, I can move it around for the best traction and no wheelstand. Great price and looks like a million bucks in the box. I liked it so much a bought another one for practice.

I had my first Gens ace 2S Lipo Battery Redline Series 5100mAh almost a year and still going strong but this exact pack has gotten puffy and takes forever to charge I think it's done, in like 3 months. I think they make great batteries maybe just a bad one or I messed up somehow, been in the hobby a long time but who knows.
