Questions about this item

How many charge cycles will the 2100mAh lithium pack deliver before it needs replacing?

Lithium-ion packs in this class usually keep useful capacity for several hundred full cycles; with regular marine use you can expect multiple seasons before a swap is needed.

What stops the BP-245N compatible pack from running longer on a single all-day outing?

The 15.54 Wh capacity is the hard limit; once the 2100 mAh at 7.4 V is depleted the radio will shut down until recharged.

Does the 177.6 g pack get hot or noisy during continuous transmit cycles?

The battery itself has no moving parts and runs silently; it warms slightly under heavy transmit but stays within normal operating temperature for lithium chemistry.
