## Customer Reviews

### ⭐⭐⭐⭐⭐ Not a direct fit for LaTrax Alias, But a great little package.
*by S***. on September 30, 2025*

Great Little Package for the price. cool, simple charger. DOES NOT FIT LaTrax Alias Drone without modification to the battery holder.

### ⭐⭐⭐⭐⭐ Perfect battery!
*by C***N on February 7, 2026*

Battery last a long time and I could fly rc planes for a long time. The price is unbeatable and and the quality is great.

### ⭐⭐⭐⭐⭐ Not 25C
*by A***R on February 23, 2024*

I previously stated that these batteries are unable to deliver 3 amps without dropping below 3 volts. I was wrong. The mating cables I was using in the test had excessive resistance. I don't know if they are really 25C, but URGENEX deserves 5 stars for their customer service. They refunded my money when I didn't even request a refund.
