    I got a healthy dose of warning by some of the RC boards about Venom. I took the risk due to the price and so far so good. The guys at Big Squid RC rated the Venoms pretty high after an extensive comparison test. I cycled the batteries only 3 times and 0 issues.

    I bought two of these batteries to put in my Traxxas Slash 4×4 with Mamba Monster 2. These batteries are cheap in price for the power they provide.

    This was my first Venom LiPo battery, but I love it. I wish it were hardcase, but since I don’t normally bash too hard, it should be fine. The Venom universal plug system is genius! Now, I don’t have to bother with soldered plugs! On a side note, my original intention was to run this battery with the Mamba Max Pro 2400kv motor from Castle Creations, but this battery does not supply enough power for that system. Well, it still makes my stock VXL system scream!

    Being new to the hobby, I really do not have a lot to compare this to, but I will say this battery makes my Traxxas Slash scream! I was also impressed with how long the run time lasts! Unless I’m running up and down the street at top speed, bashing around for a half an hour is no problem! Venom has sold me on their products and I will be purchasing more of these batteries! They seem very affordable compared to other brands as well!

    This battery is the best battery I have ever used! I threw it in my Slash and it hauled ass! I’ve been running it for a good 2 hours and the battery is still going hard. I’ve had to re-glue the tires because of this battery 3 times today! I will always love Venom batteries and will definitely be buying more.

    There are no problems so far with it. It is like the universal adapters.

    Again, first time user of RC vehicles so have nothing to compare this battery to BUT, holy smokes, this makes the Traxxas Slash Ultimate run like it is supercharged. HUGE difference between this and the NiMh, but go figure. Very pleased with the battery, attachments, and use-life.
