    BBS02 Only Pulls 21 Amps

    Ok, this one is driving me batty... I have a BBS02 and according to my display (DPC-14) it will only pull a maximum of 21 amps. Now before you go blasting me, I have the programming cable and it's set to 25 amps in the software AND the same display shows 30 amps when I hook it up to a BBSHD with a separate battery for that bike. I purchased the '02 unit from Luna a few years back and it supposedly has the upgraded mosfets but I'm left confused why it won't pull the rated 25 amps ever. I'm running it with a 13.5ah NCR-B bottle battery... am I seeing the max output of the battery?

    That was my first thought. Is the BBSHD programmed to 30 amps (indicating that the display is accurate)?

      The display does *not* measure the current or power but just reports what the controller is telling it

      Battery internal BMS can limit the current too

        Yeah the BBSHD is programmed to 30. Maybe what I'm seeing is that the different controllers are reporting differently? Maybe I should hook up the higher amp battery to the 02 to see what happens.
