12V/24V automatic identification charger, lead-acid battery (lithium battery, Ni-MH battery is not available) solar charge controller, only supports photovoltaic solar panels as a charging source. When the charging battery is 12V, choose the 17-22V solar panel; when the charging battery is 24V, choose the 30-42V solar panel for charging. Charging with mismatched voltage will damage the controller. Charging and discharge status display, cumulative power generation and discharge query, temperature display. Light control + delay control, adjustable charge and discharge parameters, with power-off memory function. Built-in over the current, short circuit, open circuit, reverse connection, protection; self-recovery protection, does not damage the controller and extends the service life.

This is a low-cost, small-size Submersible Pump Motor that can be operated from a 2.5 ~ 5V power supply. It can take up to 120 liters per hour with a very low current consumption of 220mA. Just connect the tube pipe to the motor outlet, submerge it in water, and power it. Make sure that the water level is always higher than the motor. A dry run may damage the motor due to heating and it will also produce noise.

The XH-M603 is a PCB control module used to charge lithium batteries, Lead-acid, nickel-cadmium, nickel-metal hydride, lithium-ion, and polymer. You can assemble your own Lithium battery charger by using this charger module. The 12v-24v Battery Protection Module can also be used for solar panels. The XH-M603 module is perfect for building a battery charging station, offering a range of protection features and easy-to-set min/max charging voltages. As soon as the desired battery float voltage is reached, the charging circuit is disconnected.
