Venom Fly 30C 2S 300mAh 7.4V LiPo Battery with JST and E-flite PH Plug x2 Pack Combo - Compare to E-flite EFLB2802S30

I bought these to run my FCU in my Polarstar Airsoft rifle. I charged it about a month ago and I have played a 7 days worth of serious Airsoft (semi/full auto) and no signs of the battery weakening at all...I’m also running my hop up tracer unit off this thing and it’s still holding up like a champ. I would use no other battery for this application.Update: 01/15/20 I’m still using 1 of 2 batteries on the initial charge I did back when I received it on 11/21/19 and I have played quite a few day games using it. I’ve even connected my hop up tracer unit to it. So it is now powering my Polarstar fcu and my tracer unit and hasn’t lost charge. Going to 2 milsim events in March. Let’s see if it makes it through the both of them.

The media could not be loaded.  Bought 8/1/21Reviewed 9/6/21I have had these batteries for a little over a month now and haven’t had any issues. Even flew at the beach several times and had a blast.What I like about them:- batteries cycled at least 10 times at various charging rates with no problems.- solid 6 minute flight times with no loss of power after many cycles.- fits in my UMX Turbo Timber just fine with no balance issues.- great price for 2 batteries.What I don’t like:- They didn’t come with any Velcro.- The extra power leads are a slight pain, but do give you more options for using them with multiple planes.Bottom line:I would definitely buy these again.

I have both an E-flite UMX Pitts and an E-flite UMX Turbo Timber. The Pitts uses a red JST-RCY plug and the Turbo Timber uses a white JST-PH plug.With these Venom Fly 30C 2S 300mAh 7.4V LiPo Batteries, I can use the battery in either plane. And, because they also have a standard balance plug, I can use my regular charger to do a balance charge without needing a special adapter.The extra plugs do make things a little crowded under the cowl, but it's not a big issue. The size of the battery is no issue in either plane.Charge time averages just under 30 minutes at 1C, and 4-5 minute flights leave the battery with about 30% capacity.At 25 grams, they are a bit heavier than the standard E-flite 280 mAh, and a bit larger physically, but I have not had any issues with balance or performance.Since the UMX planes use a micro-velcro, it would have been nice if some had been included, but it's not enough of an issue to deduct a star.

these are the ones EFlite should include... they are awesome batteries and easy as pie to charge up as they have multiple connectors including the UMX type. Awesome for fun fun fun flight times and durability. We use these in our beloved UMX Turbo Timber, which I also recommend highly

These batteries were a perfect replacement for an old RC plane one that'd worn out. Same electrical specifications, similar form factor that allowed to fit in the housing nicely (if a bit snug), and they work great to power the plane. I can't do a direct comparison on battery life due to the old one being unusable, but so far these last more than long enough (plus being a 2-pack I'll always have an extra). There are also two different charging plugs, due to some chargers using different plugs than others.Batteries arrived quickly, in a professional 2-pack branded package like you'd see in a hobby store, which is a welcome surprise compared to the usual loose-filled anti-static bags most small electronic components come in.I will definitely return to this brand for future batteries. Great value and a large selection.

These Batteries are just great. They give my UMX Turbo Timber a lot of power and, almost three extra minutes of flight time.Highly recommend these Venom Batteries.

So far these little guys have worked flawlessly. I run them in an airsoft Polarstar Jack, and it's been notorious for bricking batteries if I forget to take them out thus far, but these survived. Would not advise leaving them in an FCU with or without auto shutoff, but it definitely made me a happy buyer not to have a brick the next weekend.

Work great in my umx timber. They are the same size as the 280mah e flight and they are a little cheaper.

light weight and perfect for my foam rc 3d plane
