The board has two 10F super capacitors, C8 & C7 connected in series for equivalent value of 5F at 5 V. Charge voltage can be set to 2.5V or 5 V with JP7, 1S and 2S configuration. For 3S and 4S, 7.5V and 10 V configuration resistor position R17 and R18 are used. External capacitors are required and C8 & C7 are disconnected using Jumper JP6.
