EPOCH 48V 30Ah (1.54kWh) GC2 - Golf Cart LiFePO4 Lithium Battery

51.2V 30Ah LiFePO4 Battery with Smart BMS, CAN Bus Communication, and IP67 Protection

When you are building a power system that needs to work day after day, battery quality matters. You need stable output, dependable protection, long service life, and a battery that can handle real-world conditions without turning into another maintenance problem. That is exactly what this 51.2V 30Ah LiFePO4 battery is built to deliver.

Designed for solar storage, electric vehicles, backup power systems, and other 48V-class applications, this lithium iron phosphate battery combines durable construction, built-in protection, and scalable system flexibility in a compact, maintenance-free package. With 30Ah of capacity at 51.2V nominal, it provides roughly 1.54kWh of stored energy, giving you a reliable foundation for applications that need clean, consistent power.

This is the kind of battery you choose when you are done dealing with short-lived batteries, unstable output, and systems that require too much attention just to stay functional. Whether you are upgrading a backup power setup, supporting a solar installation, or adding dependable energy storage to a vehicle or equipment platform, this battery is built for long-term reliability, not short-term convenience.

Stable lithium power for demanding applications

A lot of batteries are fine for light-duty use. This one is built for more serious work.

Using LiFePO4 chemistry, this battery is designed to provide stable and safe energy storage with the kind of cycle life that makes sense for systems used regularly. LiFePO4 has become a preferred chemistry for customers who care about long-term value, dependable voltage, and lower maintenance compared to older battery technologies.

For solar users, that means more reliable storage for daily cycling and backup support. For electric vehicle or equipment applications, it means a battery that can deliver consistent power without the same decline in performance many users have learned to expect from legacy setups. For backup systems, it means dependable stored energy that is ready when needed.

Compact capacity with dependable output

With 30Ah of capacity and a nominal voltage of 51.2V, this battery delivers approximately 1.54kWh of stored energy in a compact format. That makes it a strong fit for systems where space matters, but dependable output still matters just as much.

It supports 60A continuous discharge, with peak discharge capability of 100A for 10 seconds and 200A for 3 seconds. That gives it the ability to handle both steady use and short-duration surge demands without sacrificing system stability.

In plain terms, this battery is built for applications that need more than standby performance. It is designed for real operating conditions where the battery has to do actual work.

Smart BMS protection built in

The battery itself is only part of the equation. Protection and control are what help determine how well it performs over time.

This battery includes a built-in Smart Battery Management System designed to support safe operation and long-term reliability. The BMS helps protect against overcharge, over-discharge, overcurrent, and short-circuit conditions, while also supporting high and low temperature disconnects for additional safety.

That matters in any lithium system, but especially in applications where the battery may be cycling regularly or installed in harder-working environments. When you are relying on stored energy for essential performance, protection is not optional.

Built for harsh environments

Not every battery gets installed in a clean, climate-controlled room. Some are used in mobile setups, outdoor applications, garages, sheds, utility equipment, or other spaces where dust, moisture, and changing temperatures are part of the job.

This battery is built with an IP67-rated enclosure, giving it strong protection against dust and water ingress. That added durability makes it a practical fit for applications where battery reliability cannot depend on perfect conditions.

It is a simple point, but an important one. Tougher construction means fewer worries when the environment is less forgiving.

CAN Bus communication for system coordination

Compatibility becomes more important as battery systems get more advanced.

This battery supports CAN Bus communication, helping it integrate more effectively in compatible systems and making synchronized multi-battery operation easier. That is especially useful in scaled installations where batteries need to communicate and work together as part of a broader energy storage setup.

It is the kind of feature that adds value for installers, technical users, and anyone planning a system with future expansion in mind.

Scalable storage for growing power needs

A battery should not box you in the moment your energy needs grow.

This model supports up to 10 batteries in parallel for a maximum of 300Ah, giving users flexibility to build larger storage banks as system requirements increase. That makes it a smart fit for customers who want to start with a smaller setup and expand later, rather than replace the whole system when demand rises.

For solar and backup applications especially, that kind of flexibility can make system planning much easier.

Low maintenance and long cycle life

One of the biggest advantages of lithium is owning a battery that does not constantly ask for attention.

This battery is maintenance-free and rated for 4,000+ cycles, making it a strong long-term choice for users who want reliable energy storage without the usual upkeep associated with older battery technologies. No watering. No constant maintenance routine. No dealing with batteries that feel worn out long before they should.

That long cycle life also helps support better overall value. When a battery is designed to keep cycling year after year, the upfront investment makes a lot more sense.

Why customers choose this 51.2V 30Ah battery

Customers shopping for a battery like this are usually trying to solve a real problem. They want dependable energy storage, stronger safety features, and less day-to-day hassle. They want a battery that works well in real conditions and holds up over time.
