  • Arduino Lithium-ion Battery Charger – DIY Electronics

    2019-10-23u2002·u2002What is the nominal charging voltage for 3.7V Li-ion Li-Po Cell? Short answer: 4.20V. For a 3.7V Li-ion Li-Po battery the charging voltage is 4.20V (+/- 50mV) meaning we should ideally apply 4.20V to the battery, but may have deviation within the range from 4.15V to 4.25V, but not more than 4.25V strictly.

    2021-2-14u2002·u2002Stage#3: As the current drops, it reaches its lowest level which is lower than 3% of the cell's Ah rating.. Once this happens, the input supply is switched OFF and the cell is allowed to settle down for another 1 hour. After one hour the cell voltage indicates the real State-Of-Charge or the SoC of the cell. The SoC of a cell or battery is the optimal charge level which it has …

    2021-9-22u2002·u2002In this battery, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging. Li-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode. The batteries have a high energy density, no memory effect and low self …

    I tested this on my bench power supply. Current limit set to 10 mA, then slowly increased the voltage until clamping occurred. 3.58v was the cutoff for each cell 'channel.' It was surprising that it was exactly the same across each channel. Make sure 3.58v per cell is acceptable for your battery pack. The balancer does a weird pulsing thing.
