Eric loves the 2 X 18v = 36V system from Makita. It is a great way to double your power without going to a new battery platform. Everyone hates getting a new battery platform. The DLM380 from Makita is an electric lawn mower that uses the same batteries that you use for your 18V tools. If you are a Makita user and need an electric lawn mower this is a no brainer. The only bad thing is that it is only available in the UK. Lucky Brits!
