Acxico 3Pcs Solar Charge Controller Board Lithium Battery Charging Controller Auto ON/OFF Light Control Switch For DIY Street Lights Garden Lights

Used this circuit in combination with a small Mono, crystalline, solar panel, led flame diode , lithium battery, old oil lamp, on a decoration for Halloween. Works great. Circuit charges the battery during the day. Sends the stored energy in the battery to the diode light one the solar panel stops sending voltage to the circuit. Switching on the light. The price is great. The quality is top notch. Perfect welds. Great value. Buying more to build some more yard gizmos

Used this for repair of a solar string light set that stopped charging its battery. This works, but it's not quite as smart as what it replaced. For example, our tiki torches cause it to flicker and I need to cover the panel to get them to come on fully. This panel is right next to another set that either is not sensitive to the torches. Another thing I noticed is that all of my other lights turn off between midnight a 2am. However, the one repaired with one of these boards stays on all night and just gets dimmer as the night goes on. They will stay on until the sun comes up. Still happy with these, just FYI.

Essential for my garden light fixtures. They work very well with a 6x8 solar panels.

I'm excited to share my experience with the 3Pcs Solar Charge Controller Board for DIY solar energy projects. I was able to create awesome solar-powered Halloween decorations in no time with these. They are super convenient and easy to use. All you have to do is connect the solar panel, the battery, and the load to the board, and it will take care of the rest. It will regulate the voltage and current automatically, so you don't have to worry about anything. I think these are perfect for anyone who wants to play with solar power or make some fun and eco-friendly crafts.

Although I had previously reported that these do not charge, i tried again using a different one along with a different panel and battery and they do, so far, seem to work. Either the first is defective or the panel is but i doubt it's the panel as it works with other things. It should be noted, however, that these differ from the photos shown in that they are slightly longer and have a pair of diagonally located mounting holes that the photos do not show. Also, the solder pads for the light and switch are reversed than that shown. If you look closely at the photos, you'll see a trace connecting the switch pads so if you intend on using one, you'll need to scratch off that trace but there is no documentation whatsoever so it was only by chance that I noticed it. Otherwise it will be on all the time whether or not there is a switch.

I had a fancy solar light with the controller integrated into the light board...It failed, so I bypassed the controller and hooked this up inline to handle the charging and auto on/off function... They are working perfectly for months now. I will say they have a little more variance as to when they turn on and off but that is partially due to the solar panels volts out and partially due to the chips just being less sensitive probably... Anyway I used two of them, didn't test the third, both turn on within about five minutes of each other and work flawlessly.

This product works as described but doesn’t have battery over discharge protection. You’ll need to use protected batteries or add a protection circuit to your build.

Works as advertised. I replaced my defective PCB with this for a flag pole solar light with 3 rechargeable batteries. Easy to hook up with clear labels of the wire connections on the PCB.
