Hi everyone,
Coming down home stretch on a scrambler style 20x4 rear hub build and having last minute thoughts about upgrading the controller.
I purchased a 1500w 48v kentung kit from Ali. Initially it came with 12 fet 20a continuous controller with max of 40a I believe. I had a battery pack built at 48v with 20700b cells (genuine and high quality). Total capacity is approximately 21 ah. I had the BMS bypassed for discharge simply because it could only supply 30a, however it is still used on charging. I believe this pack is capable of somewhere between 75a to 95a discharge capability. I plan on relying on the LVC set at 42v on the controller for some rough discharge protection.
I purchased a sinewave KT controller with 18 fet rated for 22a continuous, 45a peak. Today I've come across another KT controller which appears to be square rated for 30a cont. and 60a peak.
Question is: is it worth replacing the sinewave with a stronger square in this case? Should I stick with the one I have and add a little solder to one of the shunt bridges? Or should I not touch anything at all and be happy that the sinewave 22a is working as intended?
This is my first build and a lot of this is very new to me. I'd prefer to stick with a KT controller for simplicity sake in not needing to build a harness and as well as the fact that they're cheap enough if I end up burning it out. Thanks in advance for any advice and thoughts.
