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.

buena potencia tengo baterias de esta desde hace 1 ao y todo okBought 2 pcs both came 1 cell dead on arrivalcome with all balanced cell, 3.8V, will tested for my plane tomorrow. very2 cheap battery. unbelievable price, only $10 and will only $7 with buddy code. will buy more, will test with my HK550 with 2 series battHello!
Yes, the price is good, include the delivery ... but not so.
Today I received the ordered battery ...
Come perfectly packaged, but after one cell was swollen!
Two cells were 3.85v and 3.87v, but that was swollen 2.8v ...
Basically, this battery is niezpolzvaema, so the price and is inherently very, very high!
Paying for something and you get ... nothing or almost nothing.
Now you have to spoil the package and remove the damaged cell to be able to use the battery at least as 2c.
Nothing that I had 3 cell pack and I have 8 pack of 2 cells ...I use this battery to power my FPV station without any problemsHKCH
Very powerful battery. Better than the "cheap" Lipos I previously bought elsewhere.La he comprado para el quad que estoy construyendo. Viene cargada y balanceada, la prueba con uno de los motores, el variador y la placa han ido bien as que espero que no me falle a la hora de la verdad.THAY CQME POFF AND NOT SAFE BUT THAYSAY GRAGE B HAS NO WARANITY AND AND DID EVEN TAKE THEM OUT OF THE BOX; SO BUYER BE AWAY YOU MAY BE GET A BOME. SO YOU CHECK YOU ORDER BEFORE YOU TAKE IN YOUR HOMEBATTER NOT GOOD AT ALLFirst I was supicious about this B-Grade battery but It delivered huge burst power to 11.1 ESC to my E-Maxx Truck 1/10.....I recommend it for budget buyers...
