The SAMSUNG INR21700-40T 4000mAh 35A battery is an original industrial (unprotected) high-power cylindrical Li-Ion battery. It is used in various high-power electrical equipment where a compact and powerful power source is required, such as:

   - rechargeable batteries for screwdrivers and other cordless power tools;

   - rechargeable batteries for electronic cigarettes;

   - rechargeable batteries for quadcopters and other radio models

 and in many other areas.

Unprotected lithium battery SAMSUNG INR21700-40T 4000mAh provides high discharge currents with small dimensions. The life of a Li-ion battery SAMSUNG INR21700-40T 4000mAh is 250 charge/discharge cycles (until the capacity drops to 60% of the nominal) under conditions of charge 6A, discharge 35A

40T Li-ion Battery 4000mAh for the best prices often use the same chargers as 18650/18700 batteries.

Li-Ion batteries cannot be soldered with a soldering iron - they are sensitive to overheating. For mounting on Li-ion batteries, contact pads are welded.

Unprotected Li-Ion batteries cannot be used without special protection boards (PCM) that protect them from overcharging and over-discharging. At a voltage below 2.5V, an unprotected Li-Ion battery fails.

21700 size batteries are a novelty among Li-ion batteries, the scope and popularity of which are constantly increasing. Due to a slight increase in size compared to 18650 batteries (diameter 21mm instead of 18mm, length 70mm instead of 65mm), the capacity of 21700 batteries increased by 20-30% compared to 18650 batteries, which gives a noticeable increase in operating time from a single charge.
