Universal battery tester it designed for easy capacity testing multiple battery types. Original it was designed for 2x18650 batteries at the same time, or 1. battery slot for wire conection throught banana conecor on side (switch for this change is on a left side).

With adapters is posible use capacity tester for other battery types. This adapters are for test purposes only NEVER use it for powering devices or try charging these!

Capacity tester use ceramic resistors for discharging energy. This resistor can reach 80°C if its on a table withnout cooling. So this design use one 30mm FAN and small heatsinks for better cooling. Resistor connection diagram on image.

Switches on top panel are for change resistivity value. On each switch is in left coner value 1 or 2 it is matcher with big number above battery slot or next capacity circuit.

Numbers on left and right side of each switch are resistivity values. Values ares design for current little under 1A.

1.5Ω for NiMh batteries

5Ω for Lion or Li-pol

12,5 for any battery over 5V (this is avaible only on number 1)

How are resistors and switches connected together its seen on one picture in gallery.

For construction it is necessary soldering iron and electrical tape or glue gun. I recommend to use crimp terminals.

If you don't understand how this works do not build this!

Battery dont have protection so with wrong soldering you can create short circuit. Resistor can reach high temperature, without proper cooling it can melt thought plastics parts.
