I'm wanting to replace my SLA battery in my T@B teardrop trailer with lithium iron phosphate. The SLA battery died on me in just over a year, because it's a huge hassle to get to the battery to check water levels and I let it get low and killed it. Luckily you don't need to "water" LiFePo batteries and in mine, the built-in BMS takes care of the concerns over charging when it's below freezing, over charging, over discharging, etc.
I have a WFCO WF8725P all-in-one power center in the T@B and it doesn't have a LiFePo specific charge profile, so I'm looking at options. One option is to replace the entire power center for about $200 with a newer model (WF8725LiS, etc). I looked into replacing the control board alone but WFCO says they don't have an option for that.
I'm also wondering about just adding an AC-DC charger (something like the a Progressive Dynamics PD9145ALV or a Victron IP65) to the current installation. I guess my question is about if you can essentially eliminate the battery charging side of the current converter and substitute a new AC>DC charger in it's place? Or is this more trouble than it's worth?
