I have 2 Power Queen lithiums in parallel and 3 power sources
"Hi Tim (that's me). If you want to expand the lifespan(cycle time) of the batteries, we recommend charging the battery to a certain level first and then discharging it to a certain level. This operation is more useful than charging and discharging at the same time all the time. Because it you keep the battery charging or discharging all the time, if the batteries are plugged into shore power or driving all the time, it is possible to reach a deep DOD(100% charge or discharge). In this case, it is not easier to control the DOD."
Obviously this isn't easy to do unless all my chargers can be configured to
- solar (Renogy 30a charge controller)
- dc-dc (Rengogy dc-dc 40a charger)
- ac-dc (power queen 20a charger)

Obviously this isn't easy to do unless all my chargers can be configured to
- turn on at say 50% DOD which in my case is 13.15 - 13.2v
- turn off before 100% which should be around 13.3v
