Which kind of battery is more suitable for electric tools?
3. Power tool battery made of LiFePO4 battery
Electric tool battery made of LiFePO4 battery
Lithium iron phosphate battery has certain advantages as the battery of power tools. Its high temperature resistance is better than other lithium batteries. At the same time, the discharge performance above 30C can be achieved. The effect is ideal at room temperature and wide temperature. Compared with Ni MH battery, its low temperature performance and energy density are better, and its service life is longer. Ni MH battery has memory effect, but LiFePO4 battery does not. At present, the technology of LiFePO4 battery has some shortcomings compared with NiMH battery, the consistency of battery is relatively poor, and the safety of battery pack is slightly worse than NiMH battery.
4. Lithium polymer power tool battery

Among the batteries for power tools, lithium polymer should be the most expensive. Lithium polymer not only has higher energy density, but also has the best performance in achieving ultra-high rate discharge. The reason why lithium polymer is expensive is that it uses some rare materials with high energy density, and its production and manufacturing technology requirements are relatively high. Its disadvantage is that its internal high temperature performance is slightly worse than that of iron phosphate battery, similar to that of Ni MH battery. The above is an introduction to the battery types of power tools. I believe that by comparing their advantages and disadvantages, everyone should have a preliminary understanding of which kind of battery is more suitable for power tool batteries.
