Review on Charger Pennant-30 (automatic, 14.8/16/19 V, arrow.amperm) by Boyan Asenov ᠌

Revainrating 5 out of 5

Full compliance with the manufacturers assurances, high quality.

In Vympel-30, you can install the Berezhok-V control board, and get an intelligent adaptive charge with asymmetric modes, as well as smooth voltage regulation, like in Vympel-57.

Pros
  • The new 20-amp Vympels have adequate domestic charging wires of 1 sq. mm of honest copper, at 20 amperes they only heat up slightly. Those who scold these wires should remember that the current and cross section standards are given for two layers of insulation and laying in an enclosed space, and here there is one layer of insulation, and wires in the open air. Good ribbed power switch heatsinks, there is thermal paste. The ammeter is of sufficient accuracy for the purpose of charging the battery. Elegant, (in my opinion), and quite strong case. You don’t need to drop it, like any complex electronics, with the exception of a special protected one, and you don’t need to drop it either. The power board is a timeless classic, a TL494 two-stroke forward with a spray iron choke. High maintainability, only platforms and paths should be treated with care so as not to be torn off. Fully working, adequate device at an affordable price.
Cons
  • Fan 40 mm, can be replaced by 60 mm 12V, but always with a current consumption of not more than 0.2A. The fan turn-on threshold can be reduced by soldering a resistor from 20 to 51 kOhm size 0805 over the one marked in the photo.

If not for this little thing, everything would be OK.

a charger with the usual functionality, but a good base for rework to smart storage
