Mobile system on a fifth wheel trailer. I currently have 2 100W flexible panels with delamination at least 5 years old, 3 12V 105AH lead acid batteries 3 years old, pwm controller. I want to upgrade to lithium with new batteries, new panels, and a new controller. I am on a budget and need to purchase items separately. Also my rig has a charge converter when connected to shore power.
I recently purchased 2 100AH Weize batteries with a maximum input of 100 amps. Not connected yet.
Question 1: Can I use my current Powermax PM4-100 Charge converter? This is a 100amp charger. It does not have a lithium setting. It works in 3 stages starts at 14.6V and steps down to a 13.6V float. There is a way to set it for a fixed voltage up to 16.5V so I can set the fixed voltage to 14.4V.
Question 2: Is there a way to limit the amperage input to the new batteries to allow a slow charge and avoid triggering the BMS? I was trying to find a device that will limit the output of the Powermax PM4, but I'm not sure what I'm looking for.
I think I need 200W of solar per battery for solar charge, but I am limited on space to install due to vents, air conditioning, satellite, etcetera. Any suggestions?
Thank you
