## Description

Charge voltage:  Lithium battery: 3.6V-16.8V (1-4 String )  When input voltage 22-28V(≤20w,≤2A), access lithium battery: 4S  When input voltage 18-22V(≤18w,≤2A), access lithium battery: 3S  When input voltage 10-14V(≤15w,≤2A), access lithium battery: 2S When input voltage 5-7V(≤12w,≤2A), access lithium battery: 1S LiFePO4 battery: 3.2V-12.8V (1-4 String )  When input voltage 18-22V(≤20w,≤2A), 4S When input voltage 12-14V(≤18w,≤2A), 3S When input voltage 9-12V(≤15w,≤2A), 2S When input voltage 4.5-7V(≤12w,≤2A), 1S  LED lights requirements:  4S can not exceed 12w 3S can not exceed 9w 2S can not exceed 5w 1S can not exceed 3w  Note： The board stable working output current: ≤ 600mA Anti-reverse charging prevents over-charge and over-discharge protection. Batteries need to be protected. The control board needs to pay attention to waterproof and insulation The LED lamp can't use boost drive The controller battery voltage is the output voltage, unlimited current limit voltage The LED lamp beads can not be used directly and need to be driven by a step-down drive or a series current limiting resistor The LED lamp beads can not be used step up driver If you need to close at night or transport storage,the switch interface SW has been reserved, and the opening can be installed by cutting We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution.   Package Includes: 3pcs

## Features

- Charging during the day, turning on the lights automatically in the evening, turning off the lights automatically at dawn, and the battery voltage is the output voltage.
- The circuit controls the output by detecting changes in the voltage of the solar panel, eliminating the need for photosensitive elements, and is suitable for a variety of batteries.
- Scope of application: solar lawn lights, landscape lights, garden lights, corridor lights, DIY street lights, etc.
- Input voltage (solar): 4.5V-28V DC.
- Note: Batteries must be used with protective plates. Battery voltage and solar panel voltage and power must match. The LED operating voltage and power connected to the output must match the battery voltage.

## Questions & Answers

**Q: Would this work for a lead acid battery?**
A: This controller would not work well for lead acid batteries. (wrong voltage/current curves). Something like the Ardest module (also available on Amazon) is designed for both applications. Depending on the size of the battery, the current ratings on the solar panels used might be considerably higher than the small lithium batteries used in solar devices,

**Q: Doesn’t charge? the battery, 3.7v 1000mah, isn’t being recharged, comes on and off via solar cell, 5v 30ma. once drained, does not rechange. no switch**
A: For a 1000mah/3.7 volt battery, solar panel will have to be putting out at least 7-10 volts at at least 300ma

**Q: So this apparently has reverse current protection but does it include overcurrent protection?**
A: no, that is why you have to use a protected battery.

**Q: Given a constant voltage input- say 5v solar cell in - is the output voltage and current constant or does it vary with battery state of charge?**
A: Output is constant regardless of battery charge as long as the sun is a consistent brightness.
