## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Tiny whoop bats
*by Q***N on June 6, 2025*

Good batteries. They hold charge well and give decent flight time for my tiny whoop. Good price and I’ve put a good amount of cycles on them with no noticeable decline in power. They seem to be pretty durable.

### ⭐⭐⭐⭐⭐ Great OEM replacements
*by J***O on March 5, 2022*

the 2 batteries that came with the cletus were never really enough in the first place, and especially once I started flying more regularly and they got worn out I wanted enough to be able to rotate through without having to wait around to fly. Did the job and fit perfect, as should be expected.Was debating getting the 450 mah version and modifying the celtus slightly to carry it. Longer flight time would've been nice but with the small size of the drone performance definitely would've been compromised.

### ⭐⭐⭐⭐⭐ Way better power handling than PH2.0
*by B***Y on January 29, 2020*

Works amazing! So much powah and punch! The old PH connector batteries would sag to 2.9 or 3 volt before landing. I quickly found out that if I ran these to that level they wouldn't recover to 3.7-3.8 after landing. When using these on tiny whoops (mine is a beta65s w 7x16 motors) set your low voltage warnings to 3.4V and land quickly after it hits. That way they should be right around your storage voltage of 3.7 to 3.8V a few minutes after you unplug. I can tell these will last a LOT longer with proper care and less voltage sag.
