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 David Plunkett

Revainrating 5 out of 5

Use as main battery for MTB LEDs

I use it as main battery for TANSOREN 4000 lumens bright waterproof LED bike light. I then left the battery that came with the lights in my MTB backpack as a backup. So between the two batteries I have about 5 hours of high beam. Very happy with it. With the TANSOREN 4000 it took about 8 hours with low beam. Make sure to charge it according to the instructions for the first time. And turn it off when not in use to keep the lights on. I haven't had any of the loading errors that some people have commented on.

Pros
  • Hands-free mode
Cons
  • Having problems
