A simple constant current power supply that outputs 12.6VDC and 10A. It comes in a robust metal enclosure (IP68 rated) with a 100,000 hour service life. It features Over-voltage, Over-current, Short Circuit, and Over-temperature safety features. This can be used for charging Li-Ion batteries similar to the one we sell but requires good knowledge of how to do so. It also works for powering LED lighting-type devices. \The device accepts 8-36V DC inputs via 14 AWG wires (The Red and Black ones)...

The Elektor DIY LiPo Supercharger/Booster (developed the electronics engineer/YouTuber GreatScott! and produced by Elektor) can charge a single-cell LiPo battery and protect it against the effects of overvoltage, overload, and short-circuits. Additionally, it can boost the battery voltage to 5V or 12V. The boosted output voltage is protected by an ‘eFuse’ IC outputting 1.52A at 5V or 0.76A at 12V maximum. The charger part of the circuit needs a +5V power supply which can be connected through...

The LiPower board is based on the incredibly versatile TPS61200 boost converter. The board is configured to be used with a LiPo battery, has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V. However, the board can also be used as a general purpose buck and boost regulator with an input voltage as low as 0.3V (default UVLO is 2.6V). With such a low input voltage and quiescent current , the board also works well in energy harvesting applications that use low...
