Lithium RV battery replacement

[Johnjayjrv]

Need some battery advice. I am looking to replace my 2 6v Lead Acid batteries with these, https://www.batteryclearinghouse.com...2v-22-5ah-pack in parallel using this https://jag35.com/products/dc-pcb-po...32028533457011. Jehu has a video showing the batteries pushing 80 Amps through that PCB board. I know I'll need to change my WFCO charger but I have a Victron MPPT that I will connect to and use a 120w panel to top it off until I get the charger swapped out. My trailer is a 26DBH-L with a 12v fridge. The batteries will be in a toolbox that I will make sure is waterproof until I can find a better solution. Does anyone see any issues with this? I honestly don't see anything pulling more than 80 Amps and that's my only concern.

What is your plan for BMS(s)?

What is your plan for BMS(s)?

They all have internal BMS'. I've tested the capacity of them and the BMS works properly as it cuts out when the voltage is low.
