Review on 🔋 18650 Battery Spacer Holder Converter Protective Sleeve Tube for 18650 Battery (Pack of 8) - Clear by Daniel Fung

When I bought these I was really hoping they would come in separate sleeves, as it turns out these are just sleeves with no plugs I bought these to use to power up my 18650s for my upcoming to attach to flight but it's my fault for not reading carefully enough They are exactly as advertised I gave them 4 stars because they are exactly as advertised but the batteries are not in any kind of 'firm' " Secure capacity so the batteries slide out fairly easily without effort. If they fit tighter I'd rate it a 5 based on feature. The plastic used is about what I expected, maybe a little stronger.
