Cutting Edge Power's 48V 1200Wh wind and solar lithium-ion battery module is the best way to pack more power and run time into a smaller space.*  Leveraging the amazing performance of our Lithium cells and the resulting smaller footprint, our battery modules provide up to +450% lifetime and +100% run time over traditional batteries!

#1: SAFE.

The cells are born in Japan from the most reputable cell manufacturers in the world that also supply Tesla and other high performance companies.  Cells are welded and installed in plastic holders.  The plastic holders are then assembled and mounted inside your solar generator.  All of this is done in Houston, TX.  Welding is done by a special machine we built that uses our own batteries!

Each cell array is continuously monitored by a high-performance Battery Management Systems (BMS).  The BMS system protects all cells against overcharging, overdischarging, as well as overcurrent.  It also equalizes all the cell voltages and keep the pack running cool.



Our lithium battery modules will be factory installed in any Cutting Edge Power solar generator when purchased together.  Adding a lithium batteries to an existing Cutting Edge Power solar generator is ordering a pizza with our custom drop downs.  

We call them modules, because our entire solar generator product line is modular.  We understand sometimes you need testing before you know how many batteries you need.  More battery modules can easily be added later and it only takes about 5 minutes.

We don’t believe in proprietary connectors or special permanent installations.  No other connection or additional assembly on your part is required!  Terminals on our battery modules allow you to quickly and easily replace old batteries.  You can even replace our batteries with a different type or manufacturer!

Why are they so small, what’s the catch?

Our battery cells were pioneered by the auto industry so they have a high energy density in order to keep cars lightweight and extend their range. This means a smaller battery pack can have up to 2x the run time as a standard SLA battery.  Combining the small size and higher energy density, our batteries will maximize your run time in a compact solar generator!

DIYers love our lithium batteries for the small footprint, cool operating temperatures and high energy density!


Our lithium batteries provide about +450% lifetime and +100% run time over traditional lead acid batteries.  Plus, they can do this in about half the size!

Compared with traditional batteries, Cutting Edge Power lithium ion batteries have a higher run time, higher cycle lifetime, better power density and charge faster.  They also weigh less than LiFePO4 and a single module can even provide a higher discharge rate than multiple SLA or LiFePO4 batteries! In wind and solar applications, our lithium batteries have proven to be superior against lead acid, NiCd, AND lithium Iron Phosphate (LiFePO4) batteries.
