from the lowes community Q&A : How long will it run on battery power only? ;Without running the gas engine, how long will the batteries last? The battery only mode is intended for a backup mode or a light-use mode. The longevity will depend on the terrain. On flat or paved terrain the battery can last over an hour while driving. The MPV will not mow in battery only mode. what does the raven run off when operating fuel or battery? The RAVEN runs off of regular unleaded gasoline. It also has the ability to operate for limited periods of time using batteries only. This battery only mode is limited to driving. Mowing and generating are only available while the engine is running. Where can I find information on batteries? ;Where can I find specifics on the electric motors and batteries in this machine, including replacement costs and longevity.? The batteries never need to be replaced but you do have to clean them after so many hours of use according to manual. The machine over all is a great machine and well worth the price and drives very easy and silently The motors are DC Brushless 48V motors. You should never need to replace these or do any sort of maintenance. The MPV has two sets of batteries. One 12V starter battery which is a pretty typical off-the-shelf battery you can get anywhere. And one 48V battery pack. The pack itself should never need replacing because its power is managed by the system and does not go through deep drain cycles. Both the 12v and 48v batteries are charged when the MPV is running on gasoline. If it were needed to be replaced I could only guess at the cost being somewhere around $100.
