Four-pack replacement for Sonocaddie US-S

This Kastar NP-120 set provides four rechargeable lithium-ion batteries built as direct replacements for the Sonocaddie US-S pack. Each cell delivers 3.7V and 2300mAh for a total energy rating of 8.51 Wh. The pack targets golfers and coaches who use AutoPlay, V300, V300 Plus or SwingShot sports training cameras and want spare power on hand.

Upgrade from single OEM packs

Buyers who currently rely on a single original battery gain three extra cells, removing the need to recharge between rounds or sessions. The jump is worth it when a full day of recording would otherwise drain the only pack you own. If you already carry multiple spares that still hold charge, the benefit is smaller.

2300mAh per cell with multi-protection circuit

Each 2300mAh cell comfortably powers a compatible camera through extended recording sessions. The built-in circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. Cells certified to UL 1642 and CE standards add a safety margin. Runtime ends when the 8.51 Wh capacity is depleted; the pack does not support higher-voltage or larger-form-factor devices.

Questions about this item

What are the exact voltage and capacity figures for each NP-120 battery?

Each cell delivers 3.7V and 2300mAh, giving 8.51 Wh of energy storage.

How do I install the four batteries in my Sonocaddie US-S or SwingShot camera?

Open the battery compartment, align each pack's contacts with the camera terminals, and press firmly until the latch clicks — the step users miss is verifying the polarity marks before closing the door.

When will the protection circuit or cells need replacement?

The built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection lasts the cell's lifetime; replace the packs when run-time drops below your needs, typically after several hundred charge cycles.
