Only in one review: Under load 10.09 V (DC-DC Step Down module rated at 10 amps); Ripple 150 mV (0–30 V, 0–7.5 A converter board); Price 5 $ (0–30 V, 0–7.5 A converter board).

0–30 V, 0–7.5 A converter board: A compact power board with good circuitry, but ripple exceeds the specification and the shunt gets hot.

DC-DC Step Down module rated at 10 amps: Suitable for undemanding loads up to 6 A, but its output voltage is unstable and it is unsafe for charging lithium batteries.
