Planning on battery upgrade
The bus came with a pair of starter batteries. I added a solenoid to separate the two and designated one as the starter and the other as the house. The former is not getting past 11.7 and the latter not past 10.6. No solar.
My daily uses are low: 12v edgestar fridge and pump for a couple minutes, propane alarm when cooking so maybe 1 hr tops. I charge my phone, etc while driving, which is a daily thing. It’s ok if the fridge is off overnight as the stuff is fine.
I can’t get to the second battery without taking out the water tank. Not impossible, though I’d need a jack which I don’t have. Regardless, that battery tray makes for a small space and different to get to, meaning not possible to fit a large battery.
My calcs say a 50ah lithium will do me fine. https://www.renogy.com/renogy-lithium-iron-phosphate-battery-12-volt-50-ah/ I don’t have outside space for lead acid which adds to the costs comparison anyway. Sound right?
Can I simply take what was charging the second battery and insert the lithium one? Does the BMS know what to do? Some say get this: Sterling Power BB1260. Thoughts on this?
