Protected for safety,
They are close to the true ratings of 2400mAh
The pcb does a great job.
They are the less costly 18650 i have seen and they work great in my flashlight.
Take a while to charge it fully.
500 characters limits.
I wish, i would have buyed ten of these.
They fit the orange/transparent case from DX.
They does not heat at all when they get charged.
My multimeter test them at 4.19 / 4.20 volts.
These fit nice my charger. no problems.
1$ less than the 2500 mAh blue battery.
100mAh is not much so get these.
