E-flite 500mAh 1S 3.7V 25C LiPo High Current UMX Connector EFLB5001S25UM MultirotorPartsReplacement Parts,1 Count (Pack of 1)

For those of you considering the purchase of the Lectron Pro 600 mAh batteries, you might want to take another look at these. Because although these ARE more expensive, they continue to perform after literally dozens of flights. I can't say the same for the Lectron Pros. Make no mistake; the performance of both these and the Lectron Pros will degrade over time. But after approximately two dozen flights, the Lectron Pros have lost more than half their capacity. When new, the Lectron Pros started out providing flights of 7 to 8 minutes, but now can barely exceed 3 minutes. The E-Flite batteries provided flights of 6 to 7 minutes, and are still able to reach 6 minutes after the same number of flights as the Lectron Pros. For me, the decision is clear. I'm spending the extra money on batteries that maintain their capacity over time. I'm buying more E-Flite batteries.

This is a top-notch battery and works very well. It provides long flight times with plenty of power. However, it does NOT come with a UMX connector as advertised in the listing's title. It comes with the larger High Current UM connector as listed later in the detail section. If you are buying this for something with a UMX plug, you will need to buy or build an adapter. I am still giving 5 stars, as I knew what I was buying and it is a great product, but not everyone will and the product description needs a little tweaking to prevent confusion.

This LiPo is a direct OEM Replacement. I use the little single cell on the Blade Nano QX2 FPV. At an easy hover I can get a little over 5mins on a flight. Outside under a little bit of wind is about 4mins. The E-flite batteries are a little expensive in my opinion. But until Lectron Pro comes out with their equivalent, I'll be using these. One of the greatest things about Eflight and Blade is Horizon Hobby's customer service. If you are ordering this battery as a spare or backup, that's one thing. But if you are ordering this because the original one is malfunctioning or not holding a charge, call Horizon Hobby. Chances are they will send you one for free :)

These batteries may be more expensive but they have more capacity than the generic versions that I tested. They consistently have longer run times before the voltage drops off.

This battery is much wider than the photo and didn’t fit, returned.

In case anyone is wondering, these are the exact same battery that comes with the Blade Nano QX2 FPV. Haven't had any issues whatsoever, and I've been using them non-stop.

This battery does not fit the model Blade XC chopper it said it would.

Need to get eflite micro jst 1.25 to 2.0 mm adapter for sportcub s. Great upgrade for plane

alles prima

Seem to be a great battery I get 8 ish minutes on a tiny whoop with 19000kv motors just cruising around and have great punch when needed. Highly recommend

Physically longer than the original batteries, but they still fit in the heli and work well.

Nice little battery, doesn’t come with any Velcro to use in my Ultra micro Sport Cub S 2. Also doesn’t say anywhere obvious when buying it that it’s UMX connector isn’t standard sized, it’s a “high current” connector and required me to buy an adapter lead which seems like a pointless money grab.

Better price than most hobby shops
