Firstly. Current limiting is a good thing. You should value it. Without it all of your electronics can be destroyed within seconds. This Is why it is built into the vesc.
Also… the fuse is something that I have come to really appreciate. It saves people from an expensive mistake.
Also with Vesc You can achieve higher motors currents whilst limiting the battery current…
You could have 80A in the motor during start up whilst only drawing 30A from the battery… the vesc is so feature rich! It’s truley an awesome piece of gear so if you buy one so your space cell can work optimally its a good investment.
Now Ask yourself on average how long does your lipo batteries last, if used without limits, before puffy the dragon pays them a visit. Some much shorter then others, especially under high Peak amp draws… eventually under high amp draws most things fail prematurely.
From my experience using lipo’s (especially the cheap ones from hobbyking aka. Zippy flight max) they can’t handle the discharge rates of unlimited-current ESC’s. They swell from being over discharged.
Using a BMS with lipo is not a common practise (alien power system does offer it though- go figure), nor recommended. LIPO is notorious for getting out of balance. They also have a naturally short life span… a BMS won’t really play a role in changing that fact. Also they shouldn’t be charged unattended…
Let me move on,
So, If you want to run your system hot and not limit the current that’s fine by me… but at least buy some very good quality lipo that are rated to handle it… the quality lipos will last through the punishment… but now sit back and wait for the ESC or motors to fail… the electronics tend not to like heat. The weakest link will fail!
Speaking from a vendors perspective I need my products to last a very long time… So there needs to be saftey limits. Just like in you car… you can never reach max speed or rpm… there are limits. Otherwise without limits I keep needing to replace parts under warranty and eventually go broke.
It also worth noting that flier can make esc with current limiting but they don’t… they also have lots of failures, can you guess why?.. Before vesc I had some current limited flier made. They actually worked well. Alien should consider it. As much as I hate to say it customers need to be protected from destroying their products.
Just so you all know the S.P.A.C.E Cell v2.0 will be 10S4P with 50A constant current - this is 30% additional capacity… & It will be ONLY 20mm longer than the existing model. Of course much more expensive too.
One of the main reasons i am doing this (increasing cont current) is due to the increasing popularity of hub motors, higher current draw is required, especially on start… Otherwise 30A continuous is actually ample for most systems…
