EPOCH 70.4V (72V) 105ah - LiMax Series - Lithium LiFePO4 Golf Cart Battery - Complete Kit

Complete Lithium Conversion Kit 70.4V 105Ah LiFePO4 with Charger, Battery Gauge, 12V Converter, Bluetooth, and OTA Updates

When you upgrade to lithium, you want more than a battery that technically fits. You want stronger power delivery, better runtime, smarter system control, and a setup that feels like a real improvement every time you use it. That is exactly what this Complete Lithium Conversion Kit is built to deliver.

Designed for demanding 72V applications, this LiFePO4 conversion kit combines serious stored energy with the components needed for a more complete and usable upgrade. With 105Ah of capacity at 70.4V, it provides roughly 7.4kWh of stored energy, giving you the kind of performance headroom that matters in systems where weak batteries and inconsistent output are not acceptable.

This is the kind of kit people choose when they are done dealing with aging battery banks, voltage sag, long charging times, and setups that never quite feel dependable under real load. Whether you are upgrading an electric vehicle, replacing an outdated battery system, or building a more capable 72V platform, this kit gives you the output, monitoring, and long-term value that make a lithium conversion worth doing right.

Serious lithium power for high-demand 72V systems

Some upgrades are minor. This one is not.

At the heart of the kit is a 70.4V 105Ah LiFePO4 battery built in a 1P22S configuration, designed for applications that need dependable energy storage and strong current handling. LiFePO4 chemistry has become the preferred choice for many users who want stable output, long service life, and fewer headaches than older battery technologies can deliver.

For users, that means more consistent power under load, less performance drop-off over time, and a system built for repeat use rather than constant compromise. If the goal is reliable performance and cleaner long-term ownership, this is the kind of battery platform that makes the upgrade feel worthwhile.

Strong discharge capability for demanding loads

Capacity is only part of the story. The real question is how the battery performs when the system actually asks something of it.

This kit supports up to 250A max continuous discharge, with peak discharge capability of 500A for 15 seconds and 1,000A for 2 seconds. That kind of output makes it well suited for applications that need strong acceleration, high-demand bursts, or consistent performance under heavier loads.

On the charging side, it supports up to 105A continuous charge current, with peak charge and regen capability up to 500A for 15 seconds. That gives the system the ability to handle substantial charging demands while supporting practical performance in real-world operation.

In plain terms, this is not built for light-duty use. It is built for applications where power delivery, responsiveness, and system confidence matter.

Complete kit with key conversion components included

One of the biggest frustrations in a lithium conversion is finding out that the battery is only one piece of the project. Chargers, converters, gauges, and compatibility details can turn a simple upgrade into a drawn-out parts chase.

This Complete Lithium Conversion Kit helps solve that by including the core components needed for a more ready-to-use solution:

• 72V 15A lithium charger

• battery gauge

• 12V converter

That makes the upgrade more straightforward and reduces the guesswork that often comes with piecing together a system from separate parts. Instead of building your own kit one component at a time, you start with a package designed to work as a more complete solution.

Bluetooth monitoring for easier system visibility

A modern power system should not leave you guessing.

This kit includes Bluetooth app support for both iOS and Android devices, allowing you to monitor system status from your phone. That gives users a more convenient way to check battery information and keep an eye on performance without opening compartments or relying on rough estimates.

For everyday owners, it makes the system easier to live with. For more technical users and installers, it adds a more useful layer of visibility for system checks and troubleshooting.

Over-the-air updates add long-term flexibility

One of the more valuable features in a connected battery system is the ability to stay current over time.

This lithium conversion kit supports over-the-air firmware updates, allowing updates and optimization without unnecessary hassle. That gives the system a more modern ownership experience and helps support long-term usability rather than leaving the product fixed in place from day one.

It is one of those features that may not be the first thing customers ask about, but once you have it, it is hard to ignore the value.

Built for long service life

Cycle life is one of the biggest reasons people move to lithium, and this kit is designed to deliver the kind of long-term performance that justifies the investment.

Rated for 3,500 cycles, this LiFePO4 system is built for repeated use in applications where the battery is expected to perform regularly, not just sit idle as occasional backup. That long cycle life helps support lower replacement frequency, better long-term value, and a more reliable ownership experience overall.

If you are upgrading because you are tired of batteries aging out too quickly or losing performance before they should, that matters.

Wide operating range and dependable thermal performance

This battery is designed to operate across a broad voltage range from 55.0V to 79.2V, with a maximum charge voltage of 79.2V. That gives it the operating flexibility needed for proper integration into compatible 72V-class systems.

It also supports charging from 0°C to 55°C and discharging from -20°C to 60°C, making it suitable for a wide range of real-world use conditions. Whether the system lives in a garage, shop, utility environment, or outdoor application, that temperature range adds confidence where lesser systems can start to show their limits.

Why customers choose this lithium conversion kit

Customers looking at a kit like this are usually trying to fix something that has become a real problem. They want better power delivery. Better runtime. Better reliability. Less maintenance. Less frustration. They want a system that works like an upgrade should.

This kit stands out because it brings together the features that actually matter in real use:

• 105Ah capacity at 70.4V
• Roughly 7.4kWh of stored energy
• LiFePO4 chemistry for long cycle life and stable performance
• 250A continuous discharge capability
• Peak discharge up to 500A for 15 seconds and 1,000A for 2 seconds
• Continuous charge support up to 105A
• Peak charge and regen support up to 500A for 15 seconds
• 72V 15A lithium charger included
• Battery gauge and 12V converter included
• Bluetooth monitoring through iOS and Android apps
• Over-the-air firmware updates
• 3,500-cycle life for long-term value
• 11-year manufacturer warranty

Ideal for

This Complete Lithium Conversion Kit is a strong fit for:

• 72V electric vehicle conversions
• performance-focused lithium battery upgrades
• utility and equipment platforms using 72V systems
• users replacing older battery technologies with a more capable lithium setup
• applications that need strong current output, app-based monitoring, and included conversion components

If you just need the lowest-cost battery replacement and do not care much about monitoring, included accessories, or long-term durability, this may be more system than you need. But if you want a serious lithium conversion with strong output, modern control features, and a more complete installation package, this kit makes a lot more sense.

It is built for people who want their upgrade to feel like an upgrade.
