Epoch 36V 100Ah Heated Bluetooth LiFePO4 Battery

Built for buyers who want a real 36V battery, not a workaround

The Epoch 36V 100Ah is a purpose-built 36V LiFePO4 deep cycle battery with 3.84kWh of stored energy, designed for systems that need stable output, long runtime, and less day-to-day maintenance. Instead of piecing together smaller batteries to hit the voltage you need, this gives you a true 36V platform in one sealed unit, which usually means a cleaner install and fewer variables to manage over time.

Big capacity that feels useful in the real world

At 100Ah and 36V, this battery gives you the kind of reserve that makes a system feel dependable rather than touchy. You are not building around the bare minimum and hoping for the best. You have meaningful usable energy for deep cycle use, backed by LiFePO4 chemistry that is known for stable performance, long service life, and more consistent power delivery than older lead-acid setups.

Cold-weather charging without the usual lithium headache

One of the strongest features here is the integrated heating system. Charging lithium batteries in freezing conditions is where a lot of otherwise good setups start causing problems, especially if the battery lives in a garage, shed, marine compartment, or anywhere that sees real winter temperatures. Epoch includes internal heating specifically to support charging in cold conditions, with a published charge temperature range down to -20°C (-4°F) with heating. That makes this a more practical option for buyers in colder climates who do not want seasonal workarounds just to keep a battery usable.

Bluetooth monitoring that gives you answers fast

This battery includes Bluetooth connectivity with support for iOS and Android apps, so checking battery status does not mean guessing from a basic indicator light or waiting until something feels off. That kind of visibility matters more than people expect. It gives you a quick read on battery condition, helps you monitor performance under load, and makes it much easier to understand what the system is doing in actual use.

Sealed and weather-ready for rougher environments

Epoch also gives this battery an IP67-rated enclosure, which means solid protection against dust and water exposure. For buyers using 36V power in places where gear gets dirty, damp, or generally treated less gently than it would in a climate-controlled room, that matters. A sealed enclosure does not just look better on a feature list. It makes the battery better suited to real operating conditions where moisture, grime, and exposure are part of the job.

Smart protection working in the background

Inside the battery is a Smart Battery Management System, which handles protection against overcharge, over-discharge, overcurrent, short circuits, and high or low temperature extremes. That is one of the biggest quality-of-life advantages of a well-built lithium battery. The system is constantly managing conditions in the background, helping protect both the battery and connected equipment without adding extra complexity for the owner.

Strong output for demanding 36V systems

This is not just a storage battery with a nice app attached. Epoch rates it for 120A max continuous discharge current, 150A max charge current for 10 seconds, and 200A peak discharge for 60 seconds. In plain English, that means it is built to handle serious power delivery, not just light-duty reserve use. For buyers comparing 36V lithium options, that output spec is a big part of what separates a battery that looks good on paper from one that can actually keep up when the system gets pushed.

Expansion stays simple

If you know you may want more runtime later, Epoch allows up to four batteries in parallel with this model. That gives you room to expand capacity while staying at 36V, which is often the cleanest path for buyers who already know the voltage they need and simply want more endurance from the system over time. It is worth noting that this model is set up for parallel expansion only, so the flexibility here is about adding runtime, not changing system voltage.

Long-life chemistry with less maintenance hanging over you

LiFePO4 is popular for a reason. It delivers the deep-cycle performance buyers want, but without the routine maintenance and shorter lifespan that tend to come with older battery types. Epoch lists this battery as maintenance-free with 3500+ cycle life, which makes it a better fit for people who want to install the battery, monitor it properly, and get on with using the system instead of constantly tending to it.

A better fit for buyers who care about reliability, not just price tags

This battery makes the most sense when you are looking for a 36V lithium option that feels properly sorted from the start. The heating matters if your winters are real. The Bluetooth matters if you want visibility instead of guesswork. The IP67 enclosure matters if the battery is going somewhere exposed. And the Smart BMS matters if you want built-in protection rather than more things to add and manage later. None of that is flashy. It is just the kind of stuff that tends to matter more after the first season of actual use than it does on the day you are comparing spec sheets.

Warranty and long-term ownership

Epoch backs this battery with an 11-year manufacturer warranty, which lines up with the long-service expectation most buyers have when they step up to a premium lithium battery. It is also consistent with how Epoch positions its battery lineup more broadly, with an emphasis on long cycle life, advanced BMS protection, and Bluetooth-enabled monitoring across its range.

In Short

What it is

The Epoch 36V 100Ah Heated Bluetooth LiFePO4 Battery is a sealed 3.84kWh deep-cycle lithium battery built for stable 36V power, strong weather resistance, and easier day-to-day monitoring. It combines LiFePO4 chemistry, internal heating for cold-weather charging, Bluetooth app connectivity, and an IP67-rated enclosure in one maintenance-free battery.

What stands out

You get 100Ah of capacity, 120A continuous discharge, a Smart BMS for protection against common electrical and temperature faults, and support for up to four batteries in parallel if you need more runtime later. With 3500+ cycle life and an 11-year warranty, it is built for buyers who want a dependable 36V lithium battery that is easier to live with over the long haul.
