Trustfire 2pcs 26650 3.7v 5000mAh Rechargeable Li-ion Battery with PCB Protected Board

These batteries have a certain strength. I used them to light LED flashlights, not only allows me to have a strong beam, but the battery can continue to be used for a long time.

These batteries are working and working on my 1000 LM flashlight! What more is there to say?

He had to return because the item I bought with him was broken.

I bought two of them. They charge and fit perfectly in my flashlight. No problem.

The battery works well and seems to be charging and not too hot. I think the key to lithium-ion batteries is to invest in a good charger. A cheap charger can overheat the lithium battery.
