## Description

Spektrum 11.1V 800mAh 3S 50C LiPo Battery: JST, SPMX8003SJ50

Review: Two thumbs up! - Spectrum batteries are a little more pricey but I think you get what you pay for. These batteries seem to last for more charges and seem to pack a little for of a punch then other brands. Overall good quality and value. I recommend for sure.
Review: Great Aircraft LiPo - I’m using this in my FMS 800mm Corsair. And it CGs out great. Fits with no problem. And gives me at least 5 or 6 mins of flight time for each flight. It’s a good option for larger small planes that are sluggish on 2s, but too heavy with the Smart 2200mAh 3s packs. No issues with puffing due to heavy duty use.
