## Description

desertcart.com: BETAFPV 4pcs BT2.0 550mAh 1S Battery 3.8V 40C/80C Lipo Battery with BT2.0 Connector Compatible for 75-85mm 1S FPV Racing Whoop Drone Quadcopters Like Meteor75 Pro FPV Drone : Toys & Games

Review: Great batteries that just barely fit in the Cetus Pro - These batteries are higher capacity than the ones that come with the Cetus Pro, but they still fit. It's a tight fit, but it works. The extra capacity lets the drone function for about an extra minute (depending on how you fly it) compared the stock ones. They aren't the cheapest batteries, but they come already prepped to fit on the tiny quad, so I can't complain. I know some people haven't been satisfied with them, but they've been great for me.
Review: Great battery - I use this for my Vision 40 FPV drone from rotor riot, and it’s great! It holds a high voltage for longer and gives me about an extra 1 to 2 minutes of flight time. In the future I’m definitely adding more of these to my arsenal.

## Features

- 【Higher Capacity】Compared with the BT2.0 450mAh 1S battery, BT2.0 550mAh 1S battery updated the capacity to 550mAh. It is capable of delivering a discharge rate of 40C (continuous) and 80C (burst). Greatly improved battery discharge performance.
- 【Powerful Performance】BT2.0 550mAh 1S Battery has stable current and voltage output and high efficiency. Larger capacity ensures strong power and increases the flight time for the whoop drones.
