Howdy internet folks
Im trying to see if this setup will work for me. I have 2 powerstations, powerstation 1 gets charged by solar and gets 100% charged by noon. Power station 2 gets charged via power station 1's 12VDC cigarette lighter port (like a daisy chain). Powerstation 2 is only 265Wh, also gets charged 100% quickly . Powerstation 2 draws about 8.2 A when charging and charges at about 99W. The appliances that connect to the smaller powerstation 2 are only small DC applicances that draw less than 80W . I was thinking about adding 2 external 12v 100Ah batteries in parallel to increase the runtime of powerstation 2. The 2 12v lifepo4 batteries would be charged using a dc-dc charger (https://www.bioennopower.com/produc...eries-bpc-1503car?_pos=1&_fid=c65b7db7d&_ss=c) and in turn the 2 batteries will connect to the smaller powerstation 1 to charge it. If I get the lifepo4 batteries with builtin BMS then that should get overcharge and undercharge protection.
Will this setup work to extend the runtime of powerstation 2 by adding external lifepo4 batteries ?
