These lithium-ion batteries come in a variety of configurations and capacities. The battery with a protection circuit provides over-voltage, under-voltage, and over-current protection. Yet, it is slim and easy to fit into many project cases with a battery size of 18mm*65mm
These batteries do not come with protection circuitry. It is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (1 Amp) or less and add a separate protection circuitry.
If you want batteries with protection, you can buy one here!
Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush, or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or the possibility of short circuits. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. As with all Lithium-ion polymer batteries and with any power source - they should be used by experts who are comfortable working with power supplies

Poor after sales service
I have received on 18650 battery but there's no response from you even after reminding you so many times

The product shown in the picture is made by Hongli, China. But in the received item there is no marking about Manufacturing details. Only BIS sticker.
However, the battery working fine after initial charging.
