Solar Suitcase & Lithium Upgrades

Tested the new MPPT solar controller with two 100W Renogy Suitcase solar panels. Charged at 12.6 Amps, the 100AH BattleBorn Lithium 12V battery charged quickly this afternoon.  🙂

First time charging with two solar panels connected in series using a MPPT controller. Using a 12' section of 10/2 cable during this test. Have a total of 36' of cable (three 12' sections) to connect panels in series while charging. Had to set the Renogy controller for Lithium battery charging profile, but the controller automatically identified the 12V battery. Saw up to 41.5V from both panels when connected in series.

Testing on 6/2 with battery door vents sealed, charging with one 100W solar panel, outside air temperature 87F and inside battery cabinet 32C or 90F. Will continue monitoring battery cabinet temps while solar charging this season:
