ETA3000 SOT23-6 5s lithium battery active balancing v2.0

Overview

The active balancing board can be built into the electric wrench battery. It is recommended to use a 100k resistor to control the balancing current. Before powering on the board, check whether the balance lines are short-circuited. If there is a short-circuit, the chip may be damaged or there may be tin connections. Weld the total negative electrode of the battery first, and then weld the balance line connectors in sequence. There is no reverse connection protection, the positive and negative cannot be reversed.

In optical fiber communication, RF is converted to light and then to RF signal. If the optical link loss is 1dB, how much is the electrical attenuation? ? ?
We only know that the optical attenuation is 1dB and the electrical attenuation is 2dB. But why is there such a quantitative relationship? ? ? :time:
