48V Li-ion Battery only getting to 50V. : r/ebikes
48V Li-ion Battery only getting to 50V. So, was given an 18650 pack, it is a 48v13ah battery, however, it only charges to 50 volts before the 54.4v charger cuts off. ... It makes sense, it would be silly for a BMS to power itself at 3.3V or 5V from the complete pack at once, particularly when the voltage is really high, as the step down losses ...

Resistors, what do I need for my 3V LEDS? [duplicate]
For the single LED (D5), the resistor must make up the difference (9V - 3V)=6V. With 15mA flowing through both resistor and LED, the resistor should be 6V/0.015 ohms. That''s 400 ohms. Nearest standard value is 390 ohms. You''re using 1% resistors? That''s OK, find one near 400 ohms. For the two-diode string, both LEDS in series take 6V …
