The battery showed better results than other batteries that do not have a charging board. With LBF batteries, the current in the maximum brightness mode for "turbo mode" flashlights was even higher than from the original batteries of the manufacturers, so the declared characteristics with LBF 18650/21700 batteries are performed better
Tests have shown that these batteries are high-quality and have good characteristics for powering powerful flashlights. Before buying, the user should find out whether batteries of a longer length of 75 mm are suitable for his flashlight, for some models of flashlights it is not suitable. as a power bank, it can power any device by discharging to a voltage of 3.2 V. this is a very convenient function for charging various gadgets away from voltage sources. The last question is the price for which they can be purchased, if it is competitive, the batteries will be very popular for high-performance devices. The batteries have an honest declared capacity, have low internal resistance, which favors a greater current that it can give to the load. I really liked their quality.
