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 ordered 2 packs and both had a cell registering ~1 volt. The rest of the cells were in perfect balance though. Luckily I did have a need for 2x 3s packs so all I had to do was remove the faulty cell from each pack. After removing the bad cells I did a few cycles and they performed flawlessly! For the price these are a great deal if youre willing to take a gamble, and have the necessary equipment and skills to disassemble/ reassemble Lipo packs. I just hope no one else gets packs like mine and attempts to charge them as is which could result in a hazardous situation!

I did around 30 cycles on this battery, and have no problem so far. I run it in 1/8 buggy with continuous 80-90A draw.
When it arrived, two cells were out of balance. With first balance charge my charger managed to squeeze in 4240mAh with perfect balance. Since then, battery is in perfect balance, and gets very little heat during hi-amp use (comparing to some "brand name" batteries). At every charge, charger squeezes in more than 4000 mAh which is more than good with this price.
Conclusion: In first 30 cycles I couldn't see any difference compared to not "B grade" batteries.

I forth to 10 times on these accumulators is made the charge after 10 cycles of flights. In flight, they work constantly 60A. In general I think that if they will work out how to write 60 cycles for the price, then it is justified.
