Sorry for the late reply. I understand now. The client wants nothing to do with either sending the unit in nor messing with it, so it'll be good 'ol fashined lead for him. But out of interest sake... The only important thing(s) when charging lithium batteries is the the correct voltages and not exceeding charge/discharge currents? obviously batteries with bms's and controllers

Hi all, I am a bit confused when it comes to old inverters or in this case old mppt controllers and new lithium batteries. So my client has a Microcare inverter model 24/5000 so 24v 5kw teamed with a Microcare 100A mppt. Now he's been using old 105ah batteries but now wants to upgrade, he is happy with sticking to lead acid but lithium shouldn't be overlooked. We were looking at the PylonTech UP2500 but when i asked Microcare themselves they said both inverter and mppt needs to go in for upgrading. From what I have been reading is the UP2500 can only work on Voltronic inverters? Though I believe, especially with the US2000/3000 is that the battery has its own charge controller and BMS. So would this not make the UP2500 capable to work with the Microcare charge controller as long as the voltages and amperages are set right?
