I can see it for a new installation, but for an existing LFP conversion I’ve found a viable alternative to a Lithium specific charger can be had (where formerly FWC in use) simply by a change in one’s charging routine…
All that’s really needed is, once the LFP is fully charged (as verified by SOC meter or voltage monitoring), simply shut down the converter charger and run strictly off the battery…What helps to make this practical is that there’s no need to float or equalize a LFP, along with the large available DOD (depth of discharge - e.g. accessible amp/hr capacity), and LFP’s near flat voltage curve…LFP’s are quite happy operating within a range of say, 90-10% SOC…As with my (2) solar controllers, the OEM Progressive Dynamics 9245 in boost mode (via charge Wizard dongle, 14.4v) in this way works perfectly when charging the LFP…Once wrapping one’s head around the LFP format (though often difficult for some! lol :) ) I seriously doubt one might perceive a genuine need for any kind of upgrade…It’s a whole lot easier to just adopt a new charging mindset that to throw money at a new fangled charger…JM Experienced Opinion…
