To the Krasnodar Territory, the parcel was about 2 weeks old. Wrapped all in bubble film. Immediately, according to the reviews, soldered additional. The Wire (shunt) that would not heat the negative line. Installed "steep" Chinese batteries (two years lay idle), assembled, turned on... Everything works for now .... Let's see how long the whole assembly will function... :)
