[Subtitle] DIY installation of 400Ah lithium-ion battery to Camper 

I need to use the cooler all night in the car!
Up until now, we had a 300Ah lead-acid sub-battery in the car, but we had been using it while saving power because it could only use about half the capacity in real terms.
This time, Ampere Time provided us with a 400Ah lithium-ion battery, so we will replace it with a lead battery as a DIY project.
At the same time, a 60A on-board battery charger was installed to increase the charging capacity.
Now we can use electricity in the camper without worrying about the remaining power of the sub-battery, so it will be more comfortable!
