DuraTrax Onyx 2S Hard Case LiPo 25C Battery Pack w/Deans (7.4V/5000mAh)
I can honestly say this is the most reliable pack in my arsenal so far. I have this pack, 3 Gen Ace 5000's and a CRC 5300. This pack was the first I bought when I ordered my B4.1 and then about a week later I bought the Gen Ace's. The CRC I picked up a few weeks back. So far the 3 Gen Ace's are all toast. The first one was my fault, so disregard that. The second one apparently had the balance plug bullet receptacle come loose internally. The third one had the negative terminal stop working internally after a couple of weeks of it just occasionally not working. Now I'm down to my original Duratrax and my CRC. The CRC is a higher C rating, though I'm not sure if I can tell. What I do know is the Duratrax battery stays almost perfectly balanced after a run. The CRC has a higher fluctuation, and therefore takes longer to fully charge/balance after a run. I charge all my batteries at 1C and have never charged higher. I'd definitely buy another Duratrax battery, particularly for practice. I'd buy them for racing as well if they were a higher C rating. My next batteries will likely be in a 65C range as now my use is 100% racing. I highly recommend these batteries though.

I've owned 2 of these for 4 years. No problems with them. My most reliable stick packs I have owned. Zero puffing. Perfect battery for a crawler. I've got 4 hours out of them per charge in a scx10. I've used them for racing as well. Not the highest punch, as per only 25c but still no problems.

Good battery at first, but I experienced the same thing as many of the other reviews, got just a few months use out of it and it puffed.

not bad for a cheap battery, but no good for racing, a couple of track days and it puffed up like a balloon and broke out of the plastic, spend the money for a better quality battery.
