B-Grade 5000mAh 2S 20C Hard-Case Lipoly Battery

B-Grade Lithium Polymer packs are great for those not-so-important models or testing.
They have a high internal resistance (thats bad), normally wont last past 60 full
high-discharge cycles and may become puffy over time.

B-Grade packs are structurally sound, but lack the performance
of our A-Grade packs such as Flightmax, Rhino and TURNIGY.

hexTronik usually sells B-grade batteries to smaller vendors who in turn sell online at a discount.
However were now offering them to you at discounted prices, for those not-so-serious applications.
