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.

Falando sobre custo beneficio, essa a melhor bateria que t tendo, muito boa e barata. Pra asa zagy a melhor, tempo de resposta e mais rapida, nao esquenta tanto como as outros de 20c... muito bom !! tanks hobbyking.Thank you for the fast shipping hobbykingQueste batterie ( ne ho comprate 2) mi sono arrivate ben bilanciate. mi sembrano buone anche se di seconda scelta. il prezzo ottimo. Consigliate!!if i read the HK disclaimer i think i am a lucky man.
i like the B-grade lipo's better than the turnigy lipo.
B-grade balance leads are more flexible, thus less prone to breakage.
i have 2 turnigy 3600mAh lipo's, one is after 40ish loads always terribly off balance (more than 0.2 volts) whilst the B-grade lipo's are always within 0,05V balance, i have over 60 cycles on them.
granted, i got slightly lower flighttimes, but it's about one minute. so not a big deal.
i have 2 3000mAh, 6 5000mAh and 4 3600mAh B-grade lipo's (all 3S) and they perform great! the 5000mAh lipo's are well over 60 cycles and still going strong! between new and now i have still the same flight times. one of the lipo's is always a little of balance. and when i charge them in the field it get's worse. but a balance cycle get's it back to spec.
overall i stick with the B-grades!
better quality than the price would expect.
better balance leads than higher grade lipo's.
