BMS shows wrong voltage, changes to 0 V under load
I made a 24 V, 4400 mAh lithium-ion battery using 18650 cells connected in a 7S 2P configuration. When I check the pack output voltage without the BMS it''s around 21 V (very low,
SOLVED: Is it Normal For BMS Voltage Reads Less
There was no smoke or anything when I plugged everything in, but the output voltage doesnt seem right. The top picture shows the output voltage of BMS,
9. Troubleshooting and Support
If a cell voltage falls below the "Allowed-to-Discharge cell voltage" setting in the battery (default 2.8V), the BMS will turn the loads off. Check the cell voltages of all batteries that are connected to the BMS

LiFePO4 Battery Troubleshooting Guide: Fix Common BMS Issues Fast
Is your LiFePO4 battery not charging or showing 0V? Learn how to fix common issues like undervoltage, overvoltage, and BMS protection triggers with our expert guide.
BMS voltage lower than pack voltage?
If the load doesn''t cause the BMS output to drop any further in voltage, then there''s something else going on inside the BMS; either something might be hooked up wrong or it might be
Has anyone else had trouble charging the battery after a low voltage
With the BMS in a state of disconnection there can be voltage across it still, but with essentially no current to back it up, so low that it may be preventing the charger from detecting
Help!! The output voltage of my bms is lower than the
Apply a load to the output terminals and measure again. If you measure 0 V, then it means that the BMS has turned off the battery. If you measure the same
