This is the Factory Replacement Lithium Ion Battery for the Lawnbott Deluxe and Evolution. You can also add this as a second Lithium battery to your existing Deluxe or Evolution and give your mower super cutting power of up to 1.25 Acres! If you have a smaller area, adding a second battery will allow you to reduce the scheduled running time since it will spend more time mowing between charges. Note: Never mix Lead Acid and Lithium Ion Batteries. |
