Gens Ace 2s Shorty LiPo Battery Pack 60C w/4mm Bullet (7.4V/4200mAh)
Bought two of these to run in my Associated B6, and they have been great. Running through them 5-6 times a week each and have had zero issues. Will definitely re-buy these when needed, great value for the price.

Gens Ace 2s Shorty LiPo Battery Pack 60C w/4mm Bullet (7.4V/4200mAh)
Never used this brand before. I heard fairly good things about Gens Ace. After running it for the last month, I'd say it's one of the lipos that I'd like to forget. There's definitely a loss in power throughout the charge. It's noticeable after about 10%. I'll be buying something better next time. 2 stars for being under $50.
