  • Does what it's supposed to be watch out for the dimensions
If you're looking to buy this for an Arrma RC car like the 3S BLX series, be careful of the dimensions. This will NOT fit in a stock chassis of something such as a Big Rock. It is too long. Not only is this 3S 5000mah battery shorter in height than the 8000mah one by Ovonic, it's longer - yes longer. So it won't fit in the battery try unless you took a big spill like I did and knocked out the piece of the chassis that holds the battery in place, limiting its physical size capacity. Unfortunately, you'll have to look elsewhere for fitment into an Arrma Big Rock rc car. I assume the other battery trays in the other 3S BLX series is the same, but I do not know for certain. Just make sure you take your measurements before you buy this. The physical dimension isn't really a fault of the battery, so review is still 5 stars as far as everything else. Packaged nicely as typical of Ovonic batteries. Graphics look superb but how about the performance and build quality. Wires are nice and thick. Not sure of the gauge, but it's nothing I'd be concerned about. Oversized if anything. Punch on it is enough to kick up a wheelie on the stock Arrma Big Rock which is quite heavy, so no complaints on that end. I purchased this two pack and don't regret it. Might be getting more for a 6S rig in the future. ... show more

  • They work great so far. Used them twice so far with no issues.
I cant rate longevity because I just received these batteries and it is the reason I havent given a better longetivity rating. I have use each of the 2 batteries twice. No issues with running them. They fit fairly tight in my traxxas truck. But snug is good! Each charge lasts a fair amount of time compared to the old school NiCad battery packs that seemed to die very quick! I havent timed myself to see how long the battery last. But I'm gonna throw 15 minutes or maybe 20. That also varies depending on where you drive the rc car or truck. If its grass in the front yard it takes a bit more power! Pavement and more solid stuff they last a bit longer. And for the record the traxxas truck I run has a brushless motor. If you have never used LiPo batteries I strongly suggest you watch some how to youtube videos before you purchase these batteries. If you are not careful with these batteries they can be extremely dangerous. So please make sure you understand how to charge and store these batteries properly. And I highly suggest getting the fireproof little storage bags for these. These also take a special charger for charging LiPo batteries. The charger must be able to balance the cells as they charge. ... show more

  • good product for price
running two of these (6S) in a Proboat Sonicwake and a Veles29 great power, plenty of punch for these power hungry boats, Deans plugs are cheap, but for the price you can change them to what ever you use. have a few sets now with several runs on each set with no problems. good runtimes.

  • 1.5yrs later and still great batteries!
These batteries are GREAT! They've outlasted my Traxxas batteries that cost $70/battery by far and at 2 for $65 they're a MUCH better value. Did have to buy a couple adapters to convert the female dean's connector to a female Traxxas which were about $5-10 for a 5pk of em. They barely fit in my Slash Ultimate 4x4 without modifications but they did fit. Will likely be buying more soon. As shown in the pic I colored the + side of the connector red with a paint marker so I didn't accidentally connect it backwards. That's the only thing that could be a problem, they can be connected wrong if you're not paying attention. Other than that these are a much better value than the Traxxas batteries I've wasted a couple hundred $ on, every one of which has swollen and will no longer charge (I'd be nervous if they did at this point because they'd likely catch fire!). Highly recommend these Ovonics batteries!! ... show more

  • Great Performance & Value
So far these batteries are great, I’ve used both several times and they perform great in my Rustler. Perform as expected at a fair price. Big fan so far and will be purchasing more for my other RC’s.
