lobo 1200 bulk charge voltage (tested) at 14,315v. required cv for 12100l "14.0V~14.4V, CC-CV". charging should in theory be ok for 12100l (did not check cv on others). lobo rather crude regarding display of battery state and load. from personal use, to ensure longer battery life (ie longer lasting + longer lifetime of batt), usage of tv + light restricted to usage of light only when absolutely needed. cell charger only when needed, else removed from socket (it still drain power when left plugged in). also when battery indicator drop to 75% tv get swapped with light only as light drain less. once every 6-8 weeks allow inverter to drain battery till inverter switch off, else avoid self-switch-off as far as possible. (been looking at replacements, current agm 3 years+).
Read from renogy website "Discharging too often
Another common way deep-cycle batteries can be damaged is by discharging them too deeply or too frequently. That might seem odd since deep cycle batteries are, after all, meant to be discharged deeply. However, they are still batteries and can be damaged if discharged below around 50% of their capacity.  
Discharging deep-cycle batteries too frequently can also damage their lifespan and performance. Deep cycle batteries are designed to be regularly discharged using most of their capacity, but if drained too quickly and without proper recharging or rest, the electrolyte solution inside the battery can become too hot, leading to permanent damage."

I would take note of Geewiz recommendations. They sell a lot of inverters and should know which batteries are compatible. We have seen that your inverter does not work on some lithiums. Reason unknown to me. 

Geewiz normally know which units are compatible. Adhere to their advice to only charge at the 10A setting.
