If your Celtis 426 shuts down after using only about 10% of the battery, the issue is likely with the battery itself or the battery management system (BMS). Sometimes, a battery can report a high charge level, but under load, the voltage drops too quickly, causing the system to shut down.
Here are a few things to check:
-
The battery may have a weak or failing cell.
-
The BMS might not be calibrated correctly and is giving a false reading.
-
Dirty or corroded terminals can also cause poor connections and unexpected shutdowns.
-
If possible, test the battery under load or try another known-good battery to compare.
A full discharge and recharge cycle might help reset the BMS. If the issue continues, the battery probably needs to be replaced.
Fortunately, this manual contains the manufacturer's procedures on the battery, including step-by-step instructions, clear images, and exploded-view illustrations — so you want to check it out if you want to go deeper.
