So mine is the Utopia mower made by Linamar. Self propelled and has a brushless (?) motor that the company claims will outperform 48V and 60V motors. We'll see how it runs. It uses 2 batteries at once, but came with 3 - seems kind of pointless. 2 or 4 would be fine.

It recommends a 24 hour charge before initial use, and then the regular charger will fully charge the batteries in 12 hours. According to the FAQ:

How often will I have to buy a new battery? • The batteries if used/stored properly have a rating of 5 years or more. Always remember not to leave batteries in temperatures below 0°C or 32°F.
