Hi all,
After some initial testing we release V1.0 of a configurable ESD charger firmware. At this moment this firmware only works together with Pauls Magic BOX (V1.55 firmware). Look in this map for the files and further details:

Fantastic job. gradually we move towards the Vectrix DIY.
Awesome - thanks, team! Going to be another week or so until I can this out - can't wait :)
ESD configurable charger firmware updated to V1.2
Works with latest Arduino 'magic box' software.
Changes in V1.2:
- bug fix; stop driving when Arduino board disconnects. (Thanks to Roger!)
- added CPA setting; reduce max charge power.
- set firmware name to "ESDcfg12"
- added more security on absence or dis-functioning Arduino board while charging.
Use at your own risk!
Tested! Fantastic Work, The laird team!
Bug fix: OK!
CPA: OK!
Picture charging CPV 154 CPA 8A
firmware name: OK
Security. Do not know how to test...
Wish list:
add also EQV and EQA.
Dream list:
Can enable comunication with EMUS BMS, so Emus sends charging parameters to magic box.
Found the ESD classic bug here also. Fast plug and unplug also freezes system in charging mode.
However if replugged again charging resumes normally, because charging orders come from arduino, not from frozen processor inside vectrix.

Without Magic box, this freezing is known to keep charging at same rate, killing the battery if no extra security system is added.
This system overcomes the freezing problem, your vectrix charges safer, and what's more it allows you to control all parameters charging parameters. I highly recommend upgrading to magic box.
Know limits of the ESD: there are 6 hardware revisions of ESD chargers. First revisions cannot tolerate outputs below 3A for long periods of time. Despite magix box allows you to program 1A in CCA, use it at your own risk: the hardware may fail. Vectrixparts can rework the ESD charger to tolerate any OUTPUT rate. They have ESD for sale already reworked.
Security; at the start of each charge stage there is a check if MB is still there. In theory, when the MB should fail or disconnect during charge stage, the charger shuts down when the voltage of that stage is reached.
A third charging stage, 'EQ', could be added. What's the need of this? I use CC as 'equalising' stage.
