Gama Sonic 3.2 V 6,000 mAh LiFePO₄ (Square Pack)

Overview

The Gama Sonic 3.2 V 6,000 mAh LiFePO4 (Square Pack) is a durable replacement battery for solar and commercial lighting that use a box-style compartment. Its rigid, square shape helps prevent movement from wind or vibration, protecting wiring and terminals. With approximately 19.2 Wh of energy (3.2 V × 6 Ah), it provides stable, safe power when paired with LiFePO4-compatible charge controllers.

When to Choose This Battery

• Use if: Your fixture specifies a 3.2 V LiFePO4 battery around 6,000 mAh and uses a square or box-style compartment.
• Use if: The light is exposed to wind or vibration (street/area lights, signage) and benefits from a rigid, secure fit.
• Avoid if: Your device requires 3.7 V lithium-ion, 6 V SLA, or a flat/low-profile pack—choose the correct voltage and form factor instead.
• Avoid if: The charger/controller is not rated for LiFePO4 chemistry.

Compatibility and Charging

• Only use with fixtures/controllers designed for LiFePO4 3.2 V batteries.
• Recommended LiFePO4 charging profile: constant-current/constant-voltage with a final charge voltage around 3.6–3.65 V per pack.
• If charging current is adjustable, limit to ≤ 0.2–0.5C (≤ 1.2–3 A) unless the device specifies otherwise.
• Match polarity: red (+) to positive, black (−) to negative. Do not reverse-connect.
• Connector styles vary by fixture—compare before purchase or reuse the existing plug if supported.

Estimated Runtime

Usable energy is typically 80–90% of nominal in real-world solar systems due to controller behavior and temperature. With ~16–17 Wh usable:

• 2 W load: about 7–9 hours
• 3 W load: about 5–6 hours
• 4 W load: about 3.5–4.5 hours

Quick check: runtime (hours) ≈ usable Wh ÷ load W.

Installation Checklist

1. Power off the fixture and disconnect the old battery.
2. Confirm the new pack’s dimensions, connector, and polarity match your fixture requirements.
3. Seat the square pack so it cannot move; use the fixture’s bracket/foam if provided.
4. Connect leads: positive to positive, negative to negative; secure cables to prevent strain.
5. Perform an initial full charge: allow 1–2 sunny days in solar fixtures or use a LiFePO4 charger until fully charged.

Care and Storage

• Inspect terminals and connectors every few months for looseness or corrosion.
• For seasonal storage, keep at ~40–60% charge and top off every 3–4 months with a LiFePO4 charger.
• Avoid deep discharge; if lights dim early, recharge promptly to protect cycle life.
• Store in a cool, dry location (ideally 32–86 °F / 0–30 °C).

Safety and Disposal

• Do not short, crush, puncture, or incinerate.
• Use only compatible LiFePO4 charge equipment; never charge unattended with non-approved chargers.
• Recycle at approved battery collection points; do not dispose of in household trash.

Alternatives

• Need a slimmer fit? Consider a 3.2 V 6,000 mAh Flat Pack style if your compartment is low-profile.
• Different system voltage? Choose a battery that matches your device (e.g., 12.8 V LiFePO4 packs for 12 V systems) rather than this 3.2 V pack.

FAQ

Is this compatible with my fixture?

It fits fixtures that specify a 3.2 V LiFePO4 battery around 6,000 mAh in a square form factor. Check your model’s manual for the required voltage, capacity, dimensions, and connector.

How long will the battery last in service?

Service life depends on depth of discharge, temperature, and charging. Many LiFePO4 packs deliver multi-year performance in outdoor use when not deeply discharged daily and kept within recommended temperatures.

Can I replace a 3.7 V lithium or 6 V SLA with this?

No. Use only the voltage and chemistry specified by your device. This pack is for 3.2 V LiFePO4 systems.

Does it come pre-charged?

Packs typically ship partially charged. For best results, allow 1–2 full sunny days (solar) or fully charge with a LiFePO4 charger before normal use.

Can I connect packs in series or parallel?

Do not reconfigure battery packs unless your system is designed for it and you are using matched packs with appropriate protection. Mismatched or improvised connections can damage batteries and equipment.
