Questions about this item

How many charge cycles can the 6450 mAh lithium polymer cells handle before capacity drops?

The 6450 mAh lithium polymer cells are rated for typical cycle life; capacity will gradually decline after hundreds of full cycles.

What limits runtime first when the 7.4 V pack runs continuously under load?

The 51 Wh capacity and internal resistance of the 7.4 V pack set the practical runtime ceiling under sustained load.

Does the built-in protection chip add noticeable heat during all-day charging?

The smart control chip manages charging efficiently, so extra heat during all-day use remains minimal.
