How tough is it to open up the bbshd to its 1500 watt full potential. I have the 52v 1000w with the 28a controller or some say 30a. To something like PAS 0 full on and pas 1-5 or 1-9 don’t really matter to me work normally??

Alright then wow that’s a lot to take in all at once, but thank you for being so accurate. Looks like I’m going to do some research and studying up before I ever take a shot at the actual reprogramming. It reminds me of when I first got into FPV drones and had to learn the Betaflight computer program and for that I had to go out and buy my self computer lol. It was tormenting but I persrevered and got to be pretty good at it with the communitys help of course. Thanks again
ok its easy. the throttle. but to set it properly you want to program the controller. this allows you to fine tune the pedal assist and other settings, wheel size, etc. how it works is pop over to here https://edrivenet.com/bafang-programming/ to grab the bafang config software and driver. ignore their recommended settings, instead hop over to https://electricbike-blog.com/2015/06/26/a-hackers-guide-to-programming-the-bbs02/ for a better guide, and I use the em3ev black profile, its pretty good. though recently i reprogrammed my profile, added another level of efficiency as im always trying to get more range rather than power. youll find its not ideal to max power throttle often, drawing the battery fast wears it down more over time. i rarely use my throttle for max power, except when im trying to speed home after a long day. even then, i do it in bursts, pedaling, etc. yo ill try to post my screenshots in a new post you can see how I program it in the utility. it makes the motor less jerky and overpowered as the stock settings usually are, more fine tuned for your bike and efficiency. double check that your profile is backed up and the new one is correct before writing the changes to the controller. how the pas is set up is PAS 0 is essentially off, rather the motor is in standby. I have it able to use throttle in this mode but I may disable that for a safety feature since you can bump the throttle accidentally, can be a problem. stock PAS 1-4 is literally all you need to climb pretty much anything. i found 5-9 redundant, so I added a more efficient PAS 1 with 36% current instead of 52% for stock. it allows the motor to just barely spin the crank for when youre going on flat cross country, cuts the wattage draw a lot. so now PAS 1 is very light assist, PAS 2 is the proper low level assist, can also climb most things with this in the largest cog, PAS 3 is a step above that, able to climb most inclines, and PAS 4 is for when its real steep real tough and you can climb that too. anything above that is virtually not gonna be used mostly. with the throttle its programmed to be set at PAS 9 or 100% motor power at the full press of the throttle. im going to write a whole guide on this shouldnt take me long.
