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

My solar garden lamp stopped working after only two years. I opened it up and found the battery fully charged, I tested the bulb and it also worked. So I concluded the circuit is gone. I could not believe when I found this little circuit board for a good price. After some simple soldering the light is working perfectly and it gives me joy whenever it comes on at night.

I used this module to replace a defective unit in an old but beautiful real metal solar fixture; no longer available. (Actually, the only component that proved defective was the photo diode meant to sense night-day, but it was easier and cheaper to replace the entire module) I should mention that if you want to use the ON-OFF capability by adding a switch you must first cut the PC board trace between the switch solder pads.(An instruction sheet would be of benefit) The one thing that surprised me about this module was that I could not find a photo diode (or a connection for one). SURPRISE: the solar cell(s) are used as the light level detector!********** EDIT BELOW**********"PHOTO DIODE" SHOULD SAY "PHOTO RESISTOR"

These are fantastic little boards. Hard to find one that auto turns off during the day and auto turns on at night and charges the battery. The other reviewer said they used a boost, but the description and my experience says you can't. At least not to 5v. It works until it powers off and then powers back on at a much smaller voltage. So doesn't really work with a booster. Either way though, cheap, economical, and working solar board. I hope I can find these again in the future.
