Review: Ottime! - Lunga durata.
Review: Top Akkus für BetaFPV Microdrohnen - Ich fliege diese Akkus mit einer BetaFPV Cetus-X und bin damit sehr zufrieden. Im Gegensatz zu den 450mAh Akkus gewinne ich etwa 1 Minute Flugzeit. Es gibt auch noch die rot-schwarzen BetaFPV-Akkus mit "LAVA" Aufdruck, die angeblich besser sein sollen. Meine Erfahrung ist hingegen, dass diese hier (hellblau-weiß) die besseren sind. Von der Lava-Variante musste ich bereits 2 Pärchen wegwerfen, da diese aufgequollen waren. Diese hier halten hingegen einwandfrei.

## 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
- Suitable Drones: BT2.0 550mAh 1S lipo battery weighs only 14g/pc with a size of 69.5*16.2*6.3mm, it is suitable for all 1S brushless drones on sale that use BT2.0 450mAh 1S batterie, including Meteor75, Meteor75 Pro. Especially for Meteor75 Pro, pilots will achieve dynamic balance and get stable and consistent power
- BT2.0 Connector: BT2.0 connector decreased the internal resistance of the connector effectively by upgrading the crimped pins to a 1.0mm banana connector and increasing the cross-sectional area of the 1.0mm banana connector
- Notice: Please do not charge a cell with physical damage or in puffed. Don't over-charge, or over-discharge batteries. Don't put it beside the high-temperature condition or a humid environment
