Lead-Acid Battery Voltage Chart For 6V, 12V, 24V, 48V Batteries
We see the same lead-acid discharge curve for 24V lead-acid batteries as well; it has an actual voltage of 24V at 43% capacity. The 24V lead-acid battery voltage ranges from 25.46V at 100% charge to 22.72V at 0% charge; this is a 3.74V difference between a full and empty 24V battery.. Let''s have a look at the 48V lead-acid battery state of charge and …
What is the cut off voltage for lithium BMS?
Determining the optimal cut off voltage for a lithium battery management system (BMS) is crucial for maximizing both performance and lifespan. The cut off voltage refers to the minimum voltage at which the BMS will stop discharging the battery, protecting it from over-discharge. When setting the cut off voltage, several factors need to be ...

Also note that balancer-protection boards usually cut off above 4.2 V. In a series configuration, the balancer-protection board will cut off when any one of the cells exceeds the cut off voltage. It can be as high as 4.35 V given the tolerances, and this can damage the cell.

NiMH Battery Voltage Chart
As can be seen from the chart: When the NiMH discharge voltage is lower than 1.1V, its power decreases rapidly. So in practice, we usually set the cutoff voltage of RC cars running NiMH to 0.9V. When it is close to 0.8V, it means that the power is almost exhausted. If you continue to use it, it will cause irreversible damage to the battery.

A Guide to Understanding Battery Specifications
• Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge.

Why do most battery protection circuits have 2.5V discharge cap?
The device itself should also measure the discharge voltage and shut off earlier than the over-discharge protecting circuit, namely at 2.5–3.0 V measured under load, depending on battery chemistry . This is called "minimum voltage for terminating discharge". Is 2.5 V too low as over-discharge cut-off?

3s Lipo, whats safe for LVC? 9.6v -9.9v? 11.0v?
My practical "must land" voltage is 3.466V/cell (10.4V for a 3S pack) and there''s quite a lot of juice to be had between 11.1V and 10.4V. After 10.4, the pack voltage curve goes over the "knee" and starts to drop pretty quickly. If you want to always land with 20% of your battery capacity unused, then by all means land at nominal voltage.

M18 low voltage cutoff is below the recommended minimum in
The battery also does not have low-voltage cutoff - there are no transistors in the battery that can cut the power. Instead, low-voltage cutoff is done by the battery detecting low voltage and signalling the tool to stop. The battery monitors each of the 5 sets of cells individually and cuts off whenever any of them drop below the minimum voltage.
