I see that the voltage rating on the new R3 can go to 26 volts. Will the T200 Thruster also handle 24 volts? I presume that I would get more thrust with the higher voltage if that is permissible.

Hi @donoldham , The T200 is designed to run best at 16V, and is rated to run well up to 20V. Beyond that, long term performance and durability has not been tested, though I can say at 27-28V there is imminent danger of overheating and burning out the thruster in minutes or less. Running beyond 20V w…

Adam, Thanks for the clear reply. In larger battery sizes, such as 80 amp hour, or 100 amp hour, it is very hard to find anything but 12 volt or 24 volt batteries. There are no 16 volt options, making it an odd voltage in the larger battery world. I will work on getting an 18 volt battery in 100 am…

It seems to me that a high current, DC to DC switching power supply would let you use those batteries. You can buy them off the shelf, but see here for some background: DC to DC Buck Converter Tutorial | Maxim Integrated See the different types of buck converters used in DC to DC buck …

Agree that not optimising for a multiple of 12V seems an odd design choice. Anyone from BR care to share the design rationale behind this? Would be interesting to understand the reasoning as it does add complication that could seemingly have been easily avoided by optimising for 12V or 24V. Thanks

Hi @YogurtyBull , 12 V is well within the operating limits of the T200, and it will run great at that voltage. It was originally intended to be nominally optimized for 12 V, but the final design ended up having more legs in terms of practical power density than expected, thus up to 20 V was deemed f…

Thanks for the quick reply. Much appreciated. Do you have any statistical failure stats for the T200? Looking to possibly use them on a transoceanic ASV and I’d like to understand typical failure modes and frequencies.

No problem! Your second question is a bit more difficult to answer, as it is entirely dependent on the environmental operating conditions. See here: [image] T200 MTBF / Duty Cycle Thrusters and Motors Hi @seetomgo , You are correct there are a lot of variables that will…

My 20ah so called 12v lithium ion golf battery is at 16v straight off the charger.

Good afternoon! On YouTube, the author connected the T200 to a 24 volt battery. Approximately 600 watts. Works good. https://www.youtube.com/watch?v=AzO50rwD9NQ
