Gama Sonic 3.2 V 3,000 mAh LiFePO₄ (with Male Adapter)

Gama Sonic 3.2 V 3,000 mAh LiFePO4 Battery (Male Adapter)

A high-capacity, lithium iron phosphate replacement battery for 3.2 V solar lighting systems that use a matching male plug. Designed for longer nighttime runtime, dependable performance, and quick, plug-in installation.

Key Specs

Voltage	3.2 V nominal (LiFePO4)
Capacity	3,000 mAh (≈ 9.6 Wh)
Chemistry	Lithium Iron Phosphate (LiFePO4)
Connector	Built-in male adapter plug
Cycle life	Typically 2,000+ cycles at moderate depth-of-discharge (actual life varies by temperature and charge profile)
Use case	Solar lamp posts, signage/billboard lighting, path/security lights, municipal/commercial fixtures

When to Choose This Battery

• You need longer runtime vs. smaller packs (e.g., 1,500–2,000 mAh).
• Your fixture specifies a 3.2 V LiFePO4 battery and accepts a matching male plug.
• Lights are hard to access and you want fewer replacements over time.
• Operating in hot/cold climates where LiFePO4’s stability is preferred.

When to Avoid

• Your light uses 3.7 V Li-ion, NiMH, 6 V/12 V lead-acid, or any chemistry/voltage other than 3.2 V LiFePO4.
• The connector or pin-out does not match your fixture’s female port.
• Your charger/controller is not designed for LiFePO4 charge profiles.

Runtime Examples

Energy available from a full charge ≈ 9.6 Wh. Actual runtime depends on LED driver efficiency, brightness settings, temperature, and solar recharge.

• 0.3 W path light: 9.6 Wh × 0.85 efficiency / 0.3 W ≈ 27 hours (spread across nights depending on daily solar charge).
• 1.0 W security light (steady on): 9.6 Wh × 0.85 / 1.0 W ≈ 8 hours.

Formula: runtime (hours) ≈ (3.2 V × 3.0 Ah × efficiency) / load (W). Use 0.80–0.90 for efficiency if unknown.

Installation (5–10 minutes)

1. Turn the fixture off and disconnect from solar input if possible.
2. Open the battery compartment and remove the old pack.
3. Match voltage/chemistry and connector orientation. Do not force the plug.
4. Seat the male adapter fully into the fixture’s female port.
5. Secure the battery, close the compartment, and power the fixture back on.
6. Allow a full day of sun for the first full charge before evaluating runtime.

Care and Safety

• Use only with a LiFePO4-compatible controller (max charge ~3.6–3.65 V for a single cell; fixture controller typically manages this).
• Do not short, puncture, crush, or expose to fire or water.
• If storing for 1+ months, charge to ~40–60% and top up every 3–6 months.
• Keep connectors clean and dry; inspect for corrosion before installation.
• Performance will drop in extreme cold; charging below freezing is not recommended unless your fixture specifically supports it.

Compatibility Checklist

• Fixture calls for 3.2 V LiFePO4 battery.
• Connector type and polarity match the existing plug.
• Physical size fits the battery compartment (check your fixture’s manual).
• Controller/charger is designed for LiFePO4 chemistry.

Pros and Cons

• Pros: Long cycle life, stable voltage, better high/low temperature tolerance than many Li-ion chemistries, simple plug-in replacement.
• Cons: Not compatible with 3.7 V Li-ion/NiMH systems; capacity gain adds size/weight vs. smaller packs.

FAQ

Will this fit my light?

Check three things: 3.2 V LiFePO4 chemistry, a matching male/female plug, and space in the battery compartment. If your current battery is 3.7 V Li-ion or NiMH, this is not compatible.

How much longer will it run than a 1,500 mAh pack?

Approximately double the capacity (3,000 vs. 1,500 mAh), so runtime can be up to ~2× longer, assuming the same load and charging conditions.

Do I need a special charger?

Use only with fixtures/controllers designed for 3.2 V LiFePO4. Most solar lights include an internal charge controller; confirm LiFePO4 compatibility in your manual.

Can I mix old and new batteries?

No. Replace all batteries in the same fixture at the same time to ensure consistent performance and to avoid over/undercharging.

How do I recycle it?

Recycle at a battery collection site that accepts lithium batteries. Do not dispose of in household trash.
