Review on Ideolco 10x 18650 20000mAh 8.4V 7.2V Rechargeable Bike Light Battery ⚡️ Power Pack for Mountain Bicycle Light with Charger + US Adapter Plug by Russell Rabbach

So this is a 'semi' long term rating. I bought this battery to pair with my new majic shine 906 as this battery had more capacity than the magic shine. This battery worked great for 6 months and I think it lasted longer than the MS battery but now it's not working. Technically, it works for 10 minutes and then turns off. I tried it with my old cheap Cree LED bulbs and it does the same thing. I think you get what you pay for but be aware it doesn't last long.
