Lithium-ion batteries are widely used in many of our electronic devices and can be used to build all sorts of cool electrical devices, but it’s important to be aware that these are governed by some basic electrical principles, and that neglecting to follow those principles can pose significant dangers.So, is it OK to mix batteries with different voltages? No, generally speaking. You may ask: "But why? I have a 36v battery and a 48v battery, can't I just combine them together for more power?" Mixing different battery voltages can be harmful because the voltage levels are not compatible. Using batteries with different voltages can...

LiFePO4 batteries have been around for a long time, but only recently have become cost-effective and accessible for DIY applications. One major advantage that LiFePO4 has over lithium-ion chemistries is its thermal and chemical stability, which means improved battery safety. Here's a list of why Jehu Garcia recommends using LiFePO4 batteries...
