Lightly patched firmware version 71.80a for Axpert MKS II 5-48

Recommended Posts

Posted (edited)

This is a beta version of the patched firmware version 71.80a, based on factory firmware version 71.80 for Axpert MKS II 5K-48, PIP-5048MG, and equivalents. It is not to be confused with factory firmware version 71.80 for the Axpert King and PIP-5048MK. The only changes are that the two premature float bugs are fixed, and the version number on the LC Display is different.

71.80a (and 71.80) should be direct update replacements for firmware versions 71.70 and 71.71. However, 71.80 handles 4 extra CAN commands, so it is probably wise to update all paralleled / 3-phase machines at once. 71.80 has unannounced and undocumented new BMS features; see this post. New ^DnnnBMS command documented (by me) here.

This is untested apart from disassembling the patches. As always, use at your own risk.

Hi Coulomb!

First time poster, long time lurker! I just wanted to let you know that i updated one of my PIP-5048MG's from 71.40 to your patched version. Unfortunately i haven't had my setup running properly until today so therefore i dont know what differences there are, but it is running fine. Updating went without a hitch. I will be updating the other one as soon as i get it hooked up. It is a newer one with 71.70 already on it, so not as big a jump.

I'd like to thank you for taking the time to fix the firmware, and look forward to any more fixes you may make to it! (lithium would be handy! 😜)
