51.2V 100Ah LiFePO4 Battery for Home Storage, Energy Solution - 5.12kWh Capacity, 3U Chassis, 3.5" Touch-Screen, Superior EV-Grade Cells, Off-Grid Easy Installation

Li Time Customer Service is equal to a DEAD BATTERY Li Time Tech Support is equal to a DEAD BATTERY. Will buy my 15K system elsewhere!

I bought these as I believed I would be able to use them to do "BMS communications" with Victron. My setup is below and they WILL communicate status to Victron (I control things with a Cerbo). The issue with these batteries is that the factory BMS allows them to charge all the way into "over voltage" protection, which will shut down the battery for 2-3 hours until the voltage drops a bit. This means that every time you charge these batteries (using LiTime's BMS as a controller) they are going to shut down when charge reaches 100%. I've reached out to LiTime and this is their response: "Single cell overvoltage, overall overvoltage, cut-off voltage and current are the three conditions for judging full charge." To me, this means that they shut themselves down as a normal part of the charge cycle. That won't work for applications like mine where we are charging on grid power and supplement with inverter power. The other issue that seems to be a problem with "most" LiTime BMS is that their BMS does not detect or calculate "small draws". This means, if you're drawing minor power from these batteries for days, the indicated SOC (State of Charge) will not be accurate. You will not be able to use these with Victron "battery communications" without going into shut down upon full charge.... That's the WHOLE POINT of having battery communications - so the battery does not over charge... This seems to be baked into the "design" of these batteries and is a pretty substantial flaw.
