I've never heard of them. That's not to say that they aren't any good though.
Batteries is not an area that you want to skimp on in this hobby. It goes with the old saying..... you get what you pay for. Especially if you are running brushless, I would spend the extra money and get some good quality name brand packs imo.
They may work well for a few runs - but when you boil them from pulling more power than they were ever designed for and they stop working - it's just money down the drain.
As Sylvester said - spend the money and get some good packs off the mark. Hurts you more intially but more fun + cheaper in the long run
just a stock revo with the titans. i only had enough to buy the revo parts and did nt have enough to go full brushless but will in the future. i have 2 very old unusable packs but wanted some new ones so i can run the revo when it is done being built.
if you been to the rc-monster fourms then you must have visited the store. look at the batteries section and mike cronnin(the store owner) has batteries already assembled and some for a "do it your self".
I've been screwed by cheap ebay batts, had some 7 cell 3000's from "AmondoTech" that were sheer garbage and were outperformed by my Radio Shack 2000's that got really hot every time I ran them. Eventually the AmondoCrap's oozed white junk all over my Pede's chassis and began making angry sizzling noises so I chucked them in the trash and never looked back.
Get some packs made by a real company, it'll be money well spent.
