Thanks for taking the time reading this question! It is greatly appreciated.
What are we doing
We (two complete noobs) are building a remote controlled boat from scratch using Arduino compatible components. With a hull created of paper-foarm soaked in glue and expoxy we aim to create a sturdy vessel capable of carrying a can of beer at a reasonable speed across the local waters.
What are we trying to use
Using an Arduino UNO for the boat, Arduino Nano for the remote control (housed in a modified PS4 controller body) and a bunch of sensors, OLED screens and NRF24L01 transceivers we have gotten the basics and some fancy extra's sorted.
However we are unsure about our most crucial components. After some failed attempts we have discovered we need a motor with enough torque or/and a gearbox to be able to propel our vessel within actual water. These higher specced motors also require a beefier power source and thus we've been looking into LiPo-batteries. This is where we got stuck!
Our research has brought us to selecting the following components:
2x RS PRO Geared DC Motor, 7.98 W, 6 → 15 V, 78.4 gcm, 9869 rpm, ~1A operating, 5A Stall current @ https://docs.rs-online.com/216e/A700000007670040.pdf
Cytron 10A 7-30V Dual Channel DC Motor Driver Shield MDD10 @ https://www.robotshop.com/media/files/content/c/cyt/pdf/cytron-10a-7-30v-dual-channel-dc-motor-driver-shield-datasheet.pdf
Gens Ace Soaring 2200mAh 14.8V 30C 4S1P Lipo battery - XT60 plug
2x ACS712 ACS712ELC Current Sensor Module 5A
Avio Max Pro 04 20W Lipo charger
- How do we connect the LiPo battery to the Motor Driver Shield in a safe manner?
- Can the LiPo be connected using a XT60 to Dupont cable?
- Is the motor torque of 78.4 gcm / 784 ncm at 9869 rpm sufficient for water movement?
- Do we even need the current sensor modules?
- Is the charger correct for this battery?
- Any other recommended H-bridge or Motor Driver that supports near 10A?
- Shoot any holes into our plan - any and all suggestions welcome!
