Hi. I'm new to the forum. I have a 48V Ryobi Zero Turn that runs off of (4) 100AH AGM batteries. It's been about three years and now I can't get through a full cut. I would like to upgrade to LiFePo4 batteries. I'm thinking of using these ones
It is my understanding that the 50ah LiFePo4 should be about equal to a 75AH SLA battery. The Ryobi also has a 75AH AGM model. So, my question is... Could this be a drop in replacement? I store it in my shed so I was going to monitor inside temperature and shut off the AC Circuit automatically when below freezing (this battery doesn't seem to have low temp shutoff). Also, if I pre-balance and wire for 48V, can I use the existing charger? I think it only outputs 48V so probably not. If not, can I use a simple 48V 50A or lower charger and charge them in series as they sit? Since these have built in BMS units will they handle the shutoff automatically? Many thanks for any direction.
