Review on Charger Vympel 57 black by Mateusz Daczka ᠌

Review after two battery charges. There was a nuance when you first turned it on, when checking the performance. Checking according to the instructions is carried out by rotating the voltage from 5 V to 12 V. At the same time, I was able to set 5 volts only at the 1st turn-on, with a second one it was already at least 7.3 volts. Probably done to make it clear that the device has not been used before. Nuances when charging: 1) After setting the charge current, when the battery is connected and charging is turned on, the current rises by 0.1a above the initially set parameters (set 7.4a, charge current 7.5a, set 6.9a, charge current 7a). I understood after the second charge and now I set it to 0.1a below the required value. According to the instructions, the accuracy of the voltmeter is within 0.1 units. 2) After the message "charging completed", the charging process continues. According to the instructions, the inscription "charge is over" is informative and appears if the voltage has stabilized at the initially set value, and the current does not exceed 10% of the initially set value. My inscription "charge is over" appeared when the current reached 0.7a (it was set to 7a). But the charge continued. I removed the battery from charging when the recoil current reached 0.4A. Long chose the charger. I reviewed a lot of ratings, reviews, videos, and for myself I finally decided that this charger would suit me. Until I guessed wrong. Completely satisfied with the charger.
