    Product Description

    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 we're now offering them to you at discounted prices, for those not-so-serious applications.

    I have previously ordered a B-grade5000 30C - poor (less than current 25C) and heavy. Commissioned in 2650 40 - the most powerful battery !!!)) That's why, and decided to take bgrade not less than 40.

    What a rip! I knew I was taking a risk with these, but "structurally sound" doesn't even fit the description. The cells were way off at 3.6, 1.7, and 2.3. Completely unusable! Spend a few more $ on the good flightmax lipos.
