TP4056 Module Lithium Battery Charger with Protection Micro USB

The solar power management module is designed for 6V~24V solar panel. It can charge Li 3.7V battery through solar panel or USB connection, and provides 5V/1A regulated output.

Charger for 1-cell lithium-polymer batteries with a nominal voltage of 3.7 V and lithium-ion batteries. The chip is powered via a USB plug, which can be connected directly to a computer socket or a power supply.

Konnwei's KW870 car battery tester is capable of effectively analysing and reading important car data such as voltage, internal resistance, cold start current and AH capacity. In addition, the device calculates cold-start capacity and the degree of ageing, allowing for faster and more accurate repairs. Whether you're a beginner or an expert, this car battery diagnostic device can be used with a wide range of 6-18 V batteries with a capacity of 100-2000 CCA, including traditional, flat AGM, spiral AGM and gel batteries.

In the case of a battery pack, the BMS (Battery Management System) balancing protection circuit allows charging and discharging to be individually controlled. That is, the circuit controls that all cells are charged and discharged at approximately the same voltage. The current during charging should be limited, because the cell will "absorb" the current given to it, but a higher current than the one established by the manufacturer (generally a safe current is 1C ) can cause the cell to overheat and, in extreme cases, explode. The same relationship also applies to discharge.

The Konnwei KW510 is an advanced multi-function device that uses state-of-the-art technology to allow you to easily, quickly and accurately measure the actual cold start capability, battery condition and common faults in the vehicle's starting and charging systems. The KW510 is particularly useful for workshops as it can accurately detect the problem, allowing the vehicle to be repaired quickly.

This 3.7-96V 10A battery charger is an automatic charge controller module that prevents the battery from dropping below a voltage level, the value of which is adjustable. It is suitable for 1.5 to 120V batteries, as using it will save time and energy.
