Gama Sonic 3.2 V 1,500 mAh LiFePO₄ (Clip-in Pack)

A quick-swap, clip-in lithium iron phosphate battery pack for select Gama Sonic and compatible solar lights. It provides steady 3.2 V output, dependable nightly runtime, and simple, tool-free replacement for maintenance teams and homeowners.

Quick specs

Voltage	3.2 V nominal (single-cell LiFePO₄)
Capacity	1,500 mAh
Form factor	Clip-in pack (no loose leads)
Intended use	Solar pathway/area lights, signs, and outdoor fixtures designed for 3.2 V LiFePO₄ clip-in packs

When to choose this pack

• Use if your fixture specifies a 3.2 V LiFePO₄ clip-in battery and you want a fast, no-solder replacement.
• Use if you need stable cold-weather discharge and long service life typical of LiFePO₄ chemistry.
• Avoid if your light uses 3.7 V Li-ion, 1.2 V NiMH/NI-Cd cells, or a different connector/physical format—these are not interchangeable.
• Check first: tray size, clip orientation, and your fixture’s charging spec (must support LiFePO₄).

Runtime expectations

Actual runtime depends on LED brightness, driver efficiency, temperature, and how much energy your solar panel harvests during the day. Use these estimates as a planning guide:

Average current draw	Typical nightly runtime
60–80 mA (small path light)	10–16 hours
120–150 mA (medium lantern)	6–10 hours
200–250 mA (brighter area light)	4–6 hours

Assumes ~70–85% usable capacity after driver losses and temperature effects. Expect shorter runtime in winter or after cloudy days.

Installation

1. Power off the fixture and open the battery compartment.
2. Note clip orientation and polarity markers.
3. Slide the pack in until it clicks and sits flush—do not force it.
4. Close the compartment, ensuring gaskets and seals are clean for weather resistance.
5. Place the panel in direct sun for a full day to top off before first use.

Compatibility and safety

• Only for LiFePO₄ systems: Must be paired with a LiFePO₄-compatible solar charge controller (Li-ion/NiMH chargers are not suitable).
• Voltage/chemistry: Do not mix with 3.7 V Li-ion or 1.2 V NiMH packs; mismatches can cause poor performance or damage.
• Temperature: Typical LiFePO₄ charging 0–45°C (32–113°F); discharging -20–60°C (-4–140°F). Avoid charging below freezing.
• Handle with care: Do not short, puncture, or immerse. Recycle at an approved battery facility when retired.

Maintenance and lifespan

• Wipe clip contacts and battery trays periodically to remove dust and corrosion.
• If storing >3 months, charge to about 50–60% and top up every 3–6 months.
• Keep away from sustained high heat to reduce capacity fade.
• LiFePO₄ chemistry is known for long cycle life; actual cycles depend on depth of discharge, temperature, and charge profile.

Alternatives

• Need more runtime? Look for a higher-capacity 3.2 V LiFePO₄ pack that matches your fixture’s clip-in format (if supported).
• Different battery type? If your light uses AA-sized LiFePO₄ cells or NiMH packs, replace with the same chemistry and voltage specified by the manufacturer.

FAQ

How do I know if this will fit my light?

Check your fixture manual or the label inside the battery compartment for “3.2 V LiFePO₄ clip-in.” Also compare the physical tray and clip orientation before purchase.

Can I upgrade from NiMH to this LiFePO₄ pack?

No. NiMH systems use different voltages and chargers. Only use LiFePO₄ packs in fixtures designed for them.

How long does it take to recharge from solar?

With a typical small solar panel on pathway lights, a full recharge often requires a day of strong sun (roughly 6–8 peak sun hours). Cloudy weather increases charge time.

Will cold weather reduce runtime?

Yes, all batteries lose some capacity in cold conditions. LiFePO₄ discharges reliably, but you may see shorter runtimes in winter. Avoid charging below 0°C (32°F).

What should I do with the old battery?

Do not throw it in the trash. Bring used batteries to a local recycling program or hazardous waste collection site.
