HI everyone,
I've run into an issue with my Orion BMS a couple times and wondered if anyone else has as well.
I have a pack of 48 Lithiums with the EVIC monitor on my boat. I charge to 98% and have the LV alarm set at 10%. I was running along and had discharged my pack to about 78% when we stopped for lunch. On restarting the motors and proceeding my battery pack dropped to 10% setting off the alarm. Has anyone else run into this before, a sudden drop off of the voltage? I have a friend with the same system and he has seen this happen as well. Our motors (2 per boat) use a total of 60A under full speed (for our boats) so it's not like we are running anything hard. The EVIC display is suppose to show what the BMS is indicating but honestly I didn't confirm it. I've run on batteries for a number of trips but this has only happened 3 times. I've also been told that the BMS needs to "learn" and it's had months to do that.
As a side note the generator was locked out as well. Once the batteries were charged at the dock to 11% (alarm off) the genset began charging the batteries.
Any input or help in this would be greatly appreciated from such great people and site.
