12V 100Ah LiFePO4 Battery with 100A BMS for Trolling Motor, RV, Solar, Marine, Camping

Product Description

LONGER LIFE

LiFePO4 Batteries offer exceptional longevity, exceeding 2000 cycles at 100% discharge and 8000 cycles at 50% depth of discharge without performance degradation. In contrast, lead-acid batteries typically last around two years or 500 cycles at 50% discharge.

AUTOMATIC BMS AND MAINTENANCE-FREE

Weize Li-iron Batteries are equipped with a sophisticated Battery Management System (BMS) that protects against overcharging, over-discharging, overcurrent, short-circuiting, and temperature extremes, thereby enhancing performance and extending battery life.

LIGHTWEIGHT AND VERSATILE

Lithium batteries, compared to lead-acid counterparts, boast higher energy density and are at least half the weight, making them an ideal upgrade for any 12V Deep Cycle battery. They are particularly suited for various applications including fish finders, ice fishing, camping, solar systems, home alarm systems, and e-scooters. Note that these batteries should be charged with a dedicated lithium battery charger and not connected in series or parallel with more than four batteries.

SAFE AND ENVIRONMENTALLY FRIENDLY

Constructed from 100% safe, non-toxic, and non-hazardous materials, Weize LiFePO4 batteries exhibit superior chemical stability. They are resistant to thermal runaway, preventing overheating or fire hazards even if punctured. The absence of acid in these batteries allows for safe mounting in any position.

Troubleshooting Guide

Cannot Discharge:

1. Ensure the battery is securely connected.
2. Verify the correct connection of positive and negative terminals.
3. Check if battery voltage exceeds 12V; charge if below 12V.
4. Confirm the load voltage matches the battery.
5. Ensure the load current is below 100A.
6. Maintain ambient discharge temperatures between -15°C and +55°C.

Cannot Charge:

1. Ensure secure battery connections.
2. Verify correct terminal connections.
3. Confirm charging voltage matches the battery specifications.
4. Ensure charging current is below 100A.
5. Charge if battery voltage is below 9V using a charger with 0V charging function.
6. Maintain charging environment temperatures between 0°C and +45°C.
7. Disconnect the load after over-discharge protection activates and wait for voltage recovery before charging.

Battery Heats Up:

1. Ensure secure battery connections with proper contact.
2. Use cables matching the working current (6AWG or 4AWG recommended).
3. Confirm the load power does not exceed the battery discharge power of 1280W.
4. Maintain working temperatures below 55°C.

Our Service

As the leading lead-acid battery brand on Amazon, Weize guarantees its newest Lithium Iron Phosphate Batteries for 10 years. We prioritize quality and customer service. For battery-related returns, contact the seller directly as Amazon does not handle these returns. The Weize support team is always ready to assist you.

Built to Last

Our 12V 100Ah LiFePO4 Batteries endure over 2000 cycles at 100% discharge and 8000 cycles at 50% discharge, significantly outlasting lead-acid batteries which average 500 cycles at 50% discharge. This longevity translates to lower overall costs. The batteries also feature cold weather protection.

Automatic BMS and Low Temperature Cut-off

The integrated BMS safeguards against overcharge, over-discharge, overcurrent, short-circuiting, and extreme temperatures. The system automatically deactivates and reactivates the battery as needed, with a low-temperature cut-off to ensure safety and optimal performance.

Lightweight and Versatile

Lithium batteries offer higher energy density and weigh half as much as lead-acid batteries, making them ideal for upgrades in 12V Deep Cycle applications, including fish finders, ice fishing, camping, solar systems, home alarm systems, and e-scooters. Always use a dedicated lithium battery charger and avoid series or parallel connections exceeding four batteries.

Safe and Environmentally Friendly

Weize LiFePO4 batteries are made from safe, non-toxic, and non-hazardous materials, providing superior chemical stability and preventing overheating or fires even if punctured. They contain no acid, allowing for safe mounting in any position. Please read the user manual carefully and contact us with any questions.
