From Our Customers

Great battery pack, just what I needed for some light controls via Arduino, I have already ordered 5 more.

Michael W., NightShade Customer

This is the 2nd unit I have purchased from NightShade Electronics. It is very well designed, and of high quality. There are a few simple parts included as a kit to solder in place to fit one’s configuration need. The PDF instruction was very helpful in explaining how to apply it. I had some outlying questions, and the people at info@ns-electric.com were quite helpful.

Geoff, NightShade Customer

This was an excellent purchasing experience and the energyShield from Nightshade Electronics is an excellent product.

Brad Bibler, NightShade Customer

These are great for energy storage and provides excellent data. Robust and simple to code. I use them in my solar projects and wirelessly xmit data back into my house. Thanks again! Great product!

Anonymous, NightShade Customer

Purchased mine through the Kickstarter campaign, but am so glad that I have one. Need many more.

John H., NightShade Customer

Would highly recommend this. Very useful and online directions are an exact match at what you have. Have all readouts in a simple Library. Voltage, Current, Temp and Socket Voltage (Solar or Wall Plug). Using mine with Solar panel @ ~12V…the VMPP pot adjustment included is a great plus. Perfect! Nice shield!

Anonymous, NightShade Customer

This shield is awesome! Having a rechargeable battery with so many internal diagnostics greatly increases the functionality of my Arduino projects.

Daniel, NightShade Customer

This works exactly as described. I’ve integrated into a little Arduino weather station and it is working perfectly.
