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, Rhino and .
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.

This was a great purchase! I got 2 of them and run them in series to make an extremely cheap 4s 3000mah 40c lipo. I have used this on my Sky Surfer with NTM 2200kv and it is lots of fun. Im getting 10 minutes of flying with a decent amount of WOT, after landing battery & motor are not warm at all. The batt balances great and charges at 1c in no time. I even jump started my car with the 4s configuration. Its only been 10 cycles so Im not sure how they will hold up over time but I am still a big fan of this inexpensive battery.
