Review: Lunga durata.
Review: 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&voltage output and high efficiency. Larger capacity ensures strong power and increases the flight time for the whoop drones.
- 【Suitable Drone】BT2.0 550mAh 1S lipo battery weighs only 14g/pc with a size of 69.5*1 6.2*6.5mm, it is suitable for all 1S brushless drones like 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 mm banana connector and increasing the cross-sectional area of the 1 mm banana connector.
- 【Notice】Please don't 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.
