Li-ion batteries have a higher density than NiCad or NiMH batteries, so they out put more power from a smaller package
Li-ion batteries are very expensive
Li-ion battery chargers are also very expensive.
Your Li-ion Battery Is Dead -
All Cordless Tools are designed for a specific DC (direct current) voltage and amperage. The tool does not care if the electricity comes from a Li-ion, NiCad, or NiMH battery. Therefore you can run any tool on any electrical source that supplies the proper DC voltage and amperage.
It's simple - make a battery adapter for your Li-ion tool and run it from your Rambo Battery™ or Porta-Pak™ Power Station™.
You simply make a battery adapter for each cordless tool you want to run on your Multi-Voltage Rambo Battery™ or Porta-Pak™Power Station™.
Here is a Bosch 10.8 volt Li-ion battery adapter. Our Rambo Battery™ Build It! Guide™ will show you how to make adapters like this for Bosch, Dewalt, Craftsman, Ryobi, Makita, Milwaukee, Black & Decker, Skil, and others.
