Posted May 12, 2024May 12 Hi all, Im using the buwizz 3.0 pro with buwizz motors for a Technic MOC. I noticed that the claimed power output is 48w per PF port with max continuous power of 4A. However, in the buwizz app it defaults to 2A per port with a warning of exceeding this could overload the battery. The max current you can also set the battery to is only 3.5A. Am i missing something? P=IV so assuming 11V ish with 2A i get 22w per motor not 48W? Id like to be able to utilise the full 48W continuously. Thanks in advance!
May 12, 2024May 12 In such case I recommend drawing power from both ports (2A each) in order not to literally melt them.
May 12, 2024May 12 Author Tech specs from BuWizz is 4A PER channel, not combined. trying to use the full 96w continuous power I should be able to generate from two PF ports being used.
May 12, 2024May 12 The battery has a 7A lsafety imit, so the theoretical max constant power you can get is 84 Watts. I would not recommend pulling more than 2A constantly from the PF ports, as they might melt due to the contact resistance, PU ports are better for such cases due to the larger contact surface.
May 12, 2024May 12 Author That’s useful information but then I don’t understand why BuWizz advertises 96w and continuous 4A per port then when this is completely incorrect. You can only generate half the power they are claimed to provide. Edited May 13, 2024May 13 by Silicon
