330 Monster - Electronics Parts To Order

The following parts are required to complete the 330 Monster Robot Lawn Mower Project:

Its a good idea to order the parts now, so you can be printing the chassis while waiting for the parts to arrive

These parts are available as a bundle in my shop.  This ensure all the parts are compatible and fit into to the 3D printed chasis.


330 Monster Mower: Parts Required

The 330 Monster project uses a TFT touchscreen and more powerful rear wheel motors. Pack here.  (This pack can also be used for the 220 mower if you want the more powerful motors).






LiIon 18650 Batteries

In addition to these parts you will need a 3S 18650 Battery Pack. I used 6cells per pack and 3 packs in parallel making a 12.6V 20.4Ah battery. This gave a mow time on a relatively flat garden of 3hrs.  See the instructions here on creating the pack

(To create a 3S pack, 3x 18650 batteries are connected in series). A Li-Ion protector circuit was used to prevent under and over charge of the packs.

I recommend to use the Panasonic 18650B batteries. These are quality reliable  batteries and worth the investment.



the battery instructions also includes some information on batteries if your unsure how to use them
