OVONIC Lipo Battery 7.4v 1500mah 2s1p Lipo Battery Tamiya Plug Lithium Battery Suitable for Many Types of Electric Toys with Tamiya Plug

I have a gelblaster surge that I had to replace the original 500 mAh battery in after the original stopped working too soon after I bought it. I opened the gelblaster and rerouted the battery cable through the side of the blaster in a hole I drilled and filed to size. This battery pack connector fit perfectly into the original connector. Since this battery has a 1500 mAh capacity I'm able to get days of use out of it before it needs to be recharged. Presently I have the battery pack blue tapped to the handle of my blaster until I have a chance to design and print a holder that will snap fit the battery to the handle. I recommend this battery for what I'm using it for.

The battery is great. For 1500mAh it works as good as my larger Li-po batteries. I tested this out with my TT-02 and power to the wheels were the same as the larger batteries I have. It also weighs significantly less, but that is something I can't see unless I compare it side by side with another RC car with the regular batteries. The page says it has a Tamiya plug, but it is a small Tamiya plug that may fit airsoft. I had to modify mine's so I can test it. So if you are going to try this battery with an RC car it won't fit. Modifications or an adapter will be needed for the plug to function. For the price it is actually pretty good considering what you get and the discharge rate. I really recommend this battery if you want to make your TT-02 lighter at the sacrifice of play-time.

Wasn't sure what to expect from this pack as it's the highest discharge rate of any pack I've ever gotten, though only 7.4v. Tested performance on an VFC HK417 chrono'd at 430FPS. Consistently puts out RoF of about 380 with a full charge, which is pretty good for such a strong spring. Considering it's rated for 60C though I expected it to blow away my other 11.1v 5C battery packs that put out about RoF of 330, but it's only mildly better because of the lower voltage.Still, it's a solid battery pack, and does perform better than my other packs by a decent margin. Truthfully I'm not sure I'd be comfortable with it running a whole lot faster on such a strong spring, would probably start stripping gears and cracking gearboxes if it did, so this suits my needs just fine.Size is very compact, about the size of two packs of stick gum end to end.Didn't come with a USB charger but I had spares so it's not a big deal.For those curious about the Wh rating on the label, it's (mAh × V) / 1000 = Wh.So for this it's (1500 × 7.4) / 1000 = 11.1 Wh.

Excellent little 2s lipo. I can't think of a single complaint

Purchased this for my airsoft gun. It works just as well as any other lipo battery I’ve ever used, absolutely no issues with it at all. No power issues, it never cut out or anything like that.The battery life is more than enough to get you through a normal game of airsoft.It fits well in the stock of my airsoft M4, and would probably fit well in a front mounted battery compartment. May be too long for smaller battery compartments.In terms of value vs cost, I honestly can’t believe this is only $10, most batteries like this are $20-$25

This battery wasn’t the correct size needed - a failing of me, not of this product. It charged right up though & held a charge so I really wish this was the size needed because it seems very solid.

Great little spare for testing.

Holds a charge for awhile. Great for airsoft, I run ovionic brand in all my rc planes and trucks. Great battery at an unbeatable price!
