New energy battery cut-off
I''m new to lithium and want to make sure my settings are right: Charge voltage: 14.4 as specified on the battery Float voltage: 13.6??? Low voltage cutoff: 13v??? Reconnect voltage: 13.2v??? I''d like the load to be cut off at 20-30%, and before the BMS has to do it, but do these batteries really go from 90% to 20% SOC over a drop of 0.4v? - Download [PDF]

Installing Battery cut-off switch with a SmartShunt or BMV 712
Recently purchased a new RV and am about to add a battery cutoff switch (as there isn''t one now). I plan to utilize the cutoff switch to also kill power to either the SmartShunt or BMV 712 so it doesn''t draw down the battery over time. So I have two questions here I''m hoping everyone can help: 1.

What is the cut off voltage for lithium BMS?
The cut-off voltage for lithium batteries, particularly in a Battery Management System (BMS), is crucial for protecting the battery''s health. Typically, the cut-off voltage for lithium-ion cells is around 2.5V to 3.0V per cell. This threshold ensures that the battery does not over-discharge, which can lead to irreversible damage. Understanding Cut Off Voltage The …
How do I correctly set Battery Low Voltage Cut Off?
As you have a 10,440 Wh battery and know that your well measured usage is about 1/3rd of that, I would be shocked if your new battery bank was anywhere near 50%. If that doesn''t appeal to you, you might want to put an energy meter on that battery bank and see if the readings closely correlate to the specific gravity true SOC measure.
Low Battery Cut Out Limits
I have an Xantrex XW 4548 Inverter Charger and I am using a 48 volt battery bank. I noticed that the default value for the Low Battery Cut Off is 44 volts for a 48 volt system.
