Walkie-talkie (two-way radio), is able to receive electromagnetic waves, but also able to send electromagnetic waves of equipment, through its internal mediator to achieve analog signals and radio signal conversion, and then realize a certain distance communication. Small power, small size, can be held in the hand to move around the walkie-talkie, called handheld walkie-talkie, is a portable two-way radio transceiver. Due to the features of easy operation, flexible and fast, low cost, (without any network support, you can talk, no call charges incurred), in public safety, production scheduling, engineering and construction and other scenes and business, handheld walkie-talkies have become a popular communication tool for petrochemical, hotel restaurants, schools and other units. Its main power supply comes from the built-in rechargeable battery. However, in cold areas, conventional batteries cannot supply power normally, and low-temperature batteries are needed for power supply, so low-temperature walkie-talkies become an important selection factor for consumers.

-50℃~50℃ low-Temp Li-polymer Battery
-40℃~85℃ Low-Temp Ni-MH Walkie Talkie Battery
-40℃~60℃ low-temperature lithium polymer batteries are Grepow's self-developed low-temperature-resistant battery formulas, and its -40℃~60℃ low-temp Li-polymer batteries can be discharged at 0.2C in a -40℃ environment with a discharge capacity of 80%; that is, in the case of a fully charged battery, low-temperature walkie-talkies can be operated at -40℃ with a range of up to 80% of the daily range. Charging and discharging at -30℃ with 0.5C, and the battery capacity stays above 80% after 500 cycles; this meets the demand for frequent use of low-temperature walkie-talkies in extremely cold environments.

Walkie-talkie batteries on the market can be divided into lithium batteries
(Li-ion), nickel-metal hydride batteries (Ni-MH) and nickel-cadmium batteries
(Ni-Cd). In the voltage and discharge performance, nickel-metal hydride and
nickel cadmium batteries are similar, but nickel-metal hydride batteries have a
higher energy density. The capacity of one No.5 NiMH battery ranges from 600mAh
to 1800mAh, there is no "memory effect", safe and reliable, with MA
explosion-proof certification, and no pollution to the environment.Grepow, as a
source manufacturer of NiMH batteries, with 25 years of experience in
manufacturing, independent research centers and a number of customer cases, to
form a low-temperature walkie-talkie suitable for diversified solutions, such as 3S1P (3.6V) and
4S1P (4.8V), etc., commonly used capacity 1300mAh and 1800mAh.
