Rechargeable battery Bossman NCM 18650H, 3000 mAh 3,7V
Li-Ion cells (unprotected batteries) are manufactured initially. Protected banks are assembled from an unprotected Li-Ion battery (cell) and a protection board. Cylindrical rechargeable batteries have 2 current leads: screw terminals and standard contact pads.
The advantages of rechargeable Li-Ion cans: high energy density and capacity, light weight and impressive power, no "memory effect", low level of charge loss during storage, preservation of performance at negative temperatures, long service life (in the range from 300 to 1000 recharge cycles ).
The disadvantages of lithium batteries include low heat dissipation, as well as overcharge (unprotected).
They are often used in audio-video devices, mobile phones, communication systems, power tools, airsoft, laptops, aircraft models, in general, in almost all electronic devices.
The return period for batteries and accumulators is 2 days. Further goods are not subject to return and exchange.
