Questions about this item

How many charge cycles will the 10400mAh lithium pack last before it needs replacing?

The pack is built to original specifications with over-charge, over-discharge, over-voltage and short-circuit protection to maximise safe service life.

What stops the 7.4V 76.96Wh battery from running continuously during long field tests?

The 10400mAh capacity is the limiting factor; once depleted the unit must be recharged before further use.

Does the 519.2g battery get hot or make noise when powering the MTS-5800 all day?

No moving parts or fan are present; the lithium cell generates only modest warmth under normal load.
