EG4 6000EX User Settings

4 days of full 48/49v cycling. 0% till full SOC.

Still have this low cell. Tried holding it at 55v float for many hours. Its still sticking at 96-98% SOC depending on the day.

Confirm if this is fine to just ignore? Or how can I get it to equalizer and go back up like the other pack.17115595812514622835097928046056.jpg
 
The maximum differential seems to fall within a safe range for usage. Nonetheless, I'd recommend continuing to deep cycle your battery. Additionally, could you share some pictures of the battery bank and wiring? This variation could stem from differences in wire length or the battery's placement within the bank.

Fully updated both batteries. I was on old 3.32.

Also looked at the issue of resistance so I swapped the cables around. (Was POS on top left and Neg on bottom right)
Ran it for 10 days like this. And 15 or so days of down to 15/20% and back to 100 daily. Settings 56.4 float 56.4 bulk.

At around day 8/9 it reached 99.3% on the battery with the laggy cell doesn't go higher than that. And 56.8 is most I can go on the bulk without alarm(3.55v is alarm parameter).

Photo was at the very end of the bulk charge.

Also note as it goes down to float voltage. The battery with the lagging cell also consistently says its losing current. The normal one doesn't do this. It's an insignificant amount of capacity though.

And at float voltage. Seems I still get my full capacity at this time. Just hope it doesn't get worse over time. But so far so good as it is. Wil keep it on USER settings as the voltages in eg4 are still too high for the alarm/protection settings in place.

From page 4 of the LifePower4 battery manual:

WARNING: Do NOT parallel batteries by using jumper wires on the terminals. This will cause
high amperage in the final jumpers and potentially excessive amperage on the battery terminals.

I would recommend paralleling the batteries on an external bus and avoid double landing on the terminal of the batteries.

Understood and will rectify it. But within my operation I never pull more than 20A from a battery. 40A total from the bank. 40A on 6AWG is well within the wire capabilities and within the 100A output specced from the battery terminal output.

But point taken. Will place back on the bus bar and redo the 10 days.
