There are two LiPo batteries powering the robot.
We have already looked at the motor controller and its associated parts and wiring, including the 7.4-volt 2-cell LiPo battery, used to power the motor and ESCs. Now let’s take a look at the other battery.
11.4-volt 3-Cell LiPo
The other battery is an 11.4-volt 3-cell LiPo battery, that mounts in the second payload space in the Wild Thumper chassis. It powers all the electronics, and its output is divided into four fused outputs, as follows:
- 5-Volt, 10 Amp Regulator 1 Input (Output A)
- 5-Volt, 10 Amp Regulator 2 Input (Output B)
- 6-Volt, 5 Amp Regulator Input (Output C)
- 11.4-volt Battery Bus (Output D)
The fuses are mounted in an automotive fuse holder, which has a cover to protect it from moisture. It uses quick-connect lugs for all battery wires, including a 10 gauge master ground connection.
All the positive lines are well insulated. I used a combination of epoxy and hot glue to insulate and waterproof the inputs to the fuse box.
Here is the (very simple) wiring diagram:
Wow what an awesome project! I know you started this a while ago, I took a 3 month vacation from the internets, so am just catching up now. I can’t wait to see this one in action!
I mentor some students in programming for the FRC competition in a small rural community near where the Columbia River enters the USA from Canada. These students have little or no programming experience. I really appreciate the quality of your pages and presentation. We will be using your website as a primary resource for our ESP32 projects. One of our mentors has the Jetson Nano, so he might be able to move on to the 6 wheel rover, a project I like a lot, because I am interested in plant species identification.
