Hey,
I've got an Orion-Tr Smart Isolated 12/12 30 and ve.bus BMS. I'm using the Orion to charge my LiPO4's via my Sprinter's alternator.
I've got a small issue I'm hoping I can get some help with. I'd like to control the Orion's charge state in two ways. Engine ignition and BMS charge disconnect (for battery temp protection). Page 7 of the Orion's manual has a diagram showing how to hook up the BMS in conjunction with an ignition switch, but there's conflicting information. The close up in the diagram and overview are opposite.
Image below. Which is correct? Left or right diagram? BMS charge disconnect into L or H?
Thanks guys! I appreciate it.
