I have a 400ah lithium bank...4 100ah batteries connected in parallel. All connections were verified by an electrician. I have a renogy 40amp dcdc charger connected to the bank. I have a victron ip67 25amp charger connected as well with a Renogy battery monitor. I had sat parked for about one week and depleted the bank down to around 100ah. I started on a short drive with the monitor showing about 85ah remaining in the bank. I drove about three hours with the dcdc charger on. I currently have a reading on the monitor of 75ah/19% remaining. I connected the victron charger and it was set to a lithium profile but now after over 18 hours the charger has switched into storage mode and the monitor shows no change in the remaining amp hours. The charger started in bulk for about 2 hours then switched to absorption overnight and then to storage. The bank does not appear to be taking any charge. Could I have bad batteries or a bad bms in one or all of the batteries? Obviously I can't power a refrigerator or much else with 75ah on a 400ah bank. I am not sure what to do to check things out. Any ideas?
