Factory-ordered rig came installed with solar, SprintR lithium batteries, ONAN 6.5 LP genset.
First 4 trips since receiving the rig in January had no battery issues but most nights were on shore power. Due to temps, most boondock overnights had the genset running until bedtime, and on again for convection oven in the morning, etc.
These batteries have gauges on each unit. I’ve never seen any reading, on or off shore power, above 13.8.
Sunday we left for a planned 5-day boondock fishing trip. I noticed when unplugging from 50amp shore at our storage unit both batteries read 13.4. Seemed odd, but took off. Four and a half hours later, at our campsite, disconnected the truck and pushed Auto Level. The rig nose dropped as expected, and the inverter kicked out due to low battery power.
It was a battle from then on out. Two and a half hour genset runs, 2x a day, and the readings were never above 13.3. And they drained fast, kicking the inverter off 3 times. The biggest load was the 22cf residential 12v fridge.
After returning, Didn’t want to haul the rig to the dealer for the 5th time (prior slide controller, etc., issues). Pulled the batteries, had the dealer check them. Passed. Kinda sort of. Low but not failed, and not as equal as would be expected for parallel batteries.
I have found the SprintR website, but no reviews or other listings for that brand.
Thoughts?

When I received my new unit with factory installed solar I had to go thru all the settings for the solar controller and inverter to make sure it was compatible with my lithium battery. I installed a SOK 206ah. You'll need to access the battery section on the Victron App from the Smart Solar device. Some of the settings are obvious but I contacted my battery manufacturer and they provided the inputs. I also installed a victron smart shunt to get a better idea of my usage and time in float mode. You can access your solar and battery history via the app ( I sent myself and email) that'll give you an idea of your usage and states of charge. Depending on weather, I can go 3-4 days with just my 18cf residential fridge and lights burning around 5 amp/hr. My WFCO converter detects my lithium battery and will fully charge when connected to shore power.
Good luck

Thanks for the input!
I have found my solar charger had not been switched to Lithium. Was still on the factory default wet batteries.
My WFCO also auto-detects.
I have figured out I have about a 7-amp draw that I haven’t had time to identify. That’s in addition to my fridge at 1.5 amps. Haven’t had time to go down to the storage spot and search. But we have everything off, lights, demand water heater, etc. Scratching our heads…..
Hadn’t thought about contacting the battery maker for specs, but that is now on the short list.
Regards.
