## Description

Review: Great quality - Good value for price
Review: Worth the extra money - I purchased these to power my UMX Ultrix (a great little plane by the way). I also purchased another brand that was both cheaper per battery and in theory have a higher capacity at 600 mAh. After many (30+) flights I will stick with these E-Flite even though they cost more. The cheaper batteries often result in the Ultrix whining about low power shortly after launch. I am going to relegate the cheaper ones for a glider. These E-Flite batteries do not have this problem and are reliable for 6 minutes of flight.

## Questions & Answers

**Q: Again,what is the c25 designation?  my battery has c12, but the voltage and wattage is the same.  no dimension given.  is the c25 the same size??**
A: I believe it's the rate and output the battery spits out energy. The higher the # the quicker it provides energy.

**Q: Will this replace a 12C otherwise same parameters**
A: It can, provided it is the same size

**Q: my battery has 12C will the 25C work, volt and mAh are the same??**
A: It is critical that the voltage be similar. The milli Amp Hours is a unit of potential energy (endurance). As long as the physical dimensions of the batteryare not an issu and the voltage is the same,, you will be fine.

**Q: My plane came with 1s 3.7v 150mah 25c batteries…will these work instead?**
A: Without knowing your airplane, it is difficult to give you an easy answer.  
There are many factors to consider:
1: is the voltage correct
2: is the discharge current adequate
3: will it fit in the plane
4: will is disturb the cg of the plane and make it uncontrollable 
5: is it too heavy for the plane
6: does it have enough capacity for a reasonable flight time
7: are connectors compatible.  Adaptors are an option but add weight, bulk, and complexity

When jumping from a 125 mAh battery to a 500, I would be concerned about items 3, 4, 5, and 7.

I would recommend checking the connectors and dimensions of your current batteries and find a 150-200 mAh battery that satisfies the above criteria.

Good value for price

### ⭐⭐⭐⭐⭐ Worth the extra money
*by C***I on March 30, 2023*

### ⭐⭐⭐⭐⭐ Work better than other popular brands for me
*by M***P on April 6, 2023*

I now have 6 of these for my small heli and they are far better than the lectron 600mAh batteries in my application. I have 2 lectron batteries and even with the higher mAh only last about 1.5 minutes before the low voltage protection kicks in. My 4 older batteries and these 2 new batteries all last over 5 minutes flying the same way. Don't be fooled into thinking you are saving any money, flight time is all that matters. Calculate the $ per minute.
