Terms of Service & Legal Notice

By visiting our site and/or purchasing products from Sonar Cell, you engage in our "Service" and agree to be bound by the following terms and conditions, including all additional policies referenced herein.

1. Governing Law

These Terms of Service and any separate agreements whereby we provide you Services shall be governed by, interpreted, and construed in accordance with the laws of the State of Queensland (QLD), Australia, and the Commonwealth of Australia, without regard to conflict of law principles.

2. Technical Specifications & Brand Clarification

We endeavor to present accurate product descriptions, cycle life ratings, continuous discharge currents, and pricing. Independent Energy Storage Brand Notice: Sonar Cell is an independent designer and retailer of LiFePO4 battery systems and portable off-grid power stations. Sonar Cell is not affiliated with, sponsored by, or endorsed by Renogy, Battle Born Batteries, EcoFlow, Bluetti, Victron Energy, Redarc, or KickAss. Any comparative references are made strictly for BCI group sizing compatibility (e.g., Group 24 / Group 31), charging voltage profiles, and consumer guidance. Sonar Cell reserves the right to correct any inadvertent inaccuracies at any time without prior notice.

3. High-Current Electrical Safety, Series/Parallel Balancing & Marine Installation Advisory

CRITICAL HIGH-CURRENT SHORT-CIRCUIT & INSTALLATION WARNING: Deep-cycle LiFePO4 batteries can deliver massive instantaneous short-circuit currents capable of melting tools, causing severe electrical burns, and starting fires. ALWAYS use insulated wrenches when tightening M8 terminal bolts, remove all metallic jewelry/watches before working near battery banks, and install an appropriately rated Class-T or ANL main fuse within 180mm of the positive battery terminal. Series & Parallel Wiring Rules: Never connect batteries of different capacities, ages, or brands together. Before wiring identical Sonar Cell batteries in series or parallel, charge each battery individually to 100% SoC using a dedicated LiFePO4 charger so voltages are within 0.05V of one another. Charging Profile Notice: Charge exclusively using a LiFePO4-compatible charger (14.2V–14.6V absorption for 12V banks) with equalization/desulfation modes disabled. Do not use standard wet lead-acid chargers with high-voltage desulfation pulses. Sonar Cell is not liable for electrical fires caused by unfused cabling, BMS damage resulting from mismatched series/parallel wiring, or under-bonnet engine bay heat degradation (LiFePO4 batteries must be installed inside cabins, canopies, or ventilated marine lockers—never in high-heat engine compartments).
