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 bought a B grade 5000mAh 6 S 30C battery and it came with one dead cell even though HobbyKing claims all batteries are tested before shipping!!!
HK customer service when contacted asked me to fill out the online warranty, gave me a warranty RMA ID and asked me to post the battery to their warranty department in China for inspection.
There was no response and after 2 months I emailed HK customer service and was told that B Grade lipos DO NOT come with a warranty and therefore that was the end!!!
If HK does not warranty the product then why ask me to fill out the warranty form, give me a warranty RMA ID and ask me to post the battery to China for inspection!!!!
Not only did I loose money on the battery but also on the postage back to China! This is very irresponsible of HK.
So please be careful when you buy from HK. The things may be cheap but when you encounter a problem like this you end up spending more money and loose in the long run!
