Charging and balancing plate for AAA LiPo cells

Battery charging and balancing table for AAA LiPo/Li-Ion batteries. This item, manufactured by PN Racing, allows for the simultaneous charging of four AAA LiPo or Li-Ion batteries. The four batteries are connected in series and parallel to combine their voltage and amperage.

How should we connect this board to a battery charger?

To charge the 4x AAA Li-Ion batteries (PN Racing ref. EP555 ), you will need a battery charger that can charge LiPo or Li-Ion batteries, among other common battery types. If so, the charger will have a port for balancing the cells being charged, in addition to the output port with positive and negative wires for charging.

Therefore, we must connect the red (positive) and black (negative) wires to the two terminals on this charging board marked with the symbols + and -. On the other hand, we must connect the balance cable, one end to the charging board and the other end to the charger (the connector used by this balance cable is standard).

What charging parameters can we use to charge the PN Racing EP555 with this charging table?

The four 3.7V and 555mA Li-Ion cells that make up the pack (ref. EP555) are connected to each other so that, while charging, the charger balances them to ensure each reaches its maximum charge. Therefore, you must tell the charger that you are using a 4S battery (4 cells) and adjust the charging power to no more than 0.3A. This allows you to charge in LiPo mode (or in Li-Ion mode if the charger supports it).
