Lithium Deep Cycle Battery 25.6V 100Ah / LifePO4

Yes – it’s safe. The built-in BMS protects the battery from over/under-charge and other risks.

It will still charge. Most lead-acid chargers use voltages that work well with LiFePO₄.

Slightly less “full.” You may not always reach 100%, but lithium batteries don’t mind partial charge.

Turn off equalization/recondition. Those high-voltage modes are not suitable for lithium.

Cold weather note. Avoid charging below 0 °C unless the battery has low-temp protection.

Optional upgrade. A lithium-specific charger gives faster and more complete charging, but it’s not required.

We import LFP batteries for our gate automation systems and require a specific order volume to secure the best price. Likewise, the cargo volume needs to meet certain size requirements to achieve favourable shipping conditions. As a result, we import more batteries than we need for automation and sell the surplus at an attractive price to ensure quick turnover. All batteries are of the highest quality and feature A+ grade cells. Each model has undergone capacity testing and reliably holds the specified power. To date, no battery or BMS has experienced any failures.

Turtle Direct LiFePO₄ Battery Warranty Terms (NZ)

Turtle Direct warrants its LiFePO₄ batteries against manufacturing defects and workmanship for a period of 5 years from the date of purchase.

We guarantee that the battery will retain at least 80% of its rated capacity within the warranty period, provided it is used and maintained correctly.

Warranty Conditions:

• To qualify for warranty coverage: The battery must be installed, charged, and maintained according to the guidelines provided by Turtle Direct.
• The battery must not be subjected to extreme temperatures, excessive moisture, physical damage, misuse, abuse, or neglect.
• Exclusions: This warranty explicitly excludes: Normal wear and tear Damage resulting from unauthorized modifications or repairs Accidental damage or damage caused by natural disasters.
• Warranty Claims to initiate a warranty claim; contact Turtle Direct with proof of purchase and a detailed description of the issue.
• Turtle Direct may require battery testing and inspection to validate the claim. The battery has to be returned to Turtle Direct.
• Limitation of Remedies Turtle Direct reserves the right to remedy any valid claim by either providing a replacement battery or issuing a pro-rata-temporis refund based on the remaining warranty period, at our sole discretion.
• Consumer Rights: This warranty is provided in addition to, and does not exclude or limit, your rights under the New Zealand Consumer Guarantees Act 1993.

A BMS (Battery Management System) is like the brain of a LiFePO₄ (LFP) battery. It protects the battery and makes sure it runs safely and efficiently.

Here’s what it does:

• Overcharge Protection: It stops charging if the voltage gets too high, which could damage the battery or cause a fire.
• Over-discharge Protection: It disconnects the load if voltage gets too low to prevent permanent damage.
• Cell Balancing: It evens out the voltage between cells so all cells age evenly and the battery performs better over time.
• Temperature Monitoring: It shuts down charging or discharging if temperatures are too hot or too cold.
• Short Circuit and Overcurrent Protection: It disconnects the battery instantly if there's a short or a power surge.

In short, the BMS keeps the LFP battery healthy, safe, and working as long as possible. Without it, even a high-quality battery can fail early or become dangerous.
