CLASSIC - ENDAMPS - Why is ENDAMPS not triggering at my ENDAMPS setting?
Last Updated 6 years ago
This is more likely to happen with a 48 volt battery pack.
This is what is happening, you have 24 cells in your pack, near full 100% SOC bubbling at full charge. 3.5 amps is your trigger, what is happening the current is bouncing back > 3.5A faster than you can detect it BUT the Classic does, when it does it resets the 90 second ENDAMP detect timer. This is why you see the current go down to maybe 3 amps, the Classic will ENDAMP after the 90 seconds passes but your battery is now down to 3 amps in. If during this 90 second time period, bubbling exposes plates and bing, a small surge back > 3.5A and the whole thing starts again.
This issue is not as big with a 12V system like in an RV, ENDAMPS works well, you only have 6 cells to deal with.
