Kayak questions have been asked before, apologies for this, but I need some help to determine if it’s possible to power an inflatable kayak using T200 thrusters. The tandem kayak is 4 meters long and 90 cm wide. The model can be seen here.
I don’t mind going from standstill to cruising speed via paddling, turning on the thrusters only once moving. I also don’t need to do any steering via electronic controls, since the paddles can be used for this as well. I have no requirements for slowing down, or a reverse mechanism, a simple on / off switch would suffice. Multiple speed settings could be useful, mostly to regulate the speed, preventing the battery from draining too fast. My idea is to mount the thrusters on the tracking fin at the back of the kayak, perhaps with the mounting brackets.
I suppose the BlueESC option would be the easiest to start with, and perhaps a micro-controller with basic controls to achieve the on / off functionality. If you believe that for this application, there would be enough thrust provided, then I would be grateful if you could help answer the following:
- Assuming mounting will be done with the brackets in front/back orientation then distance between the two thrusters will be only a few centimeters. Is there a minimum distance requirement for proper usage?
- I assume two thrusters working at a lower RPM would provide better battery consumption rates & thrust performance, compared to one running at a higher speed. Using the chart on your website, one T200 can generate 3 lbf of thrust, using 47 Watts. Coupling two units would yield 6 lbf & 90 Watts. The charts seem to suggest that a 16V battery would yield higher thrust at lower current (16V – 2.96 vs 12V – 3.87), and lower PWM. Are 16V batteries in large capacities available on the market, and are there any downsides to 16V installation?
- Supposing that I find a 8000 – 10000 mah battery pack, is it advisable to use them individually until they are drained, or is connecting them in parallel a better option?
- Are there any suggestions for a basic micro controller that could be connected to the BlueESC by someone without any prior experience?
