EcoFlow LFP Battery for 48V Systems — 2kWh and 5kWh
This is the battery that EcoFlow's Power Kit systems are built around, sold on its own so you can expand a system you already have or build one to your own design. Lithium iron phosphate cells in a 48V package, with the battery management system, auto-heating and hot-swap capability built in.
Two sizes: 2kWh (40Ah) and 5kWh (100Ah). Up to three stack in parallel through the Terminal Busbar, so a 2kWh bank can grow to 6kWh and a 5kWh bank to 15kWh. They can be hardwired into a fixed installation or plugged in, and the mounting clamp, bracket and strap come in the box. Renewable Outdoors is an authorized EcoFlow dealer — call us at (303) 876-7654 if you'd like help matching a battery to your existing hardware.

Why the EcoFlow LFP Battery
Auto-Heating Down to −4°F
Most lithium batteries refuse to accept a charge below freezing. This one heats itself, so it keeps charging in a cold garage, a winter cabin, or an unheated van.
Up to 3500 Cycles
Rated for 3500 charge cycles at 80% depth of discharge — roughly ten years of daily use before capacity becomes a concern.
Stack Up to Three in Parallel
A Terminal Busbar links up to three batteries: 6kWh from the 2kWh size, 15kWh from the 5kWh size, all managed as one bank.
Hot-Swap Enabled
Batteries can be added or replaced without taking the whole system down, which matters when the system is what's keeping your lights on.
Advanced BMS Built In
Cell-level monitoring for voltage, current and temperature, with protection against overcharge, over-discharge, short circuit and thermal runaway.
Hardwire or Plug-and-Play
Mounts on a wall or a floor with the included clamp, bracket and strap, and wires in either way depending on how permanent your install is.
What's Included
In the Box
1 × EcoFlow LFP Battery (2kWh or 5kWh, depending on the size you choose)
Wall mounting clamp
Mounting bracket
Mounting strap
User manual and warranty card
The Terminal Busbar needed to parallel multiple batteries is a separate part, as are the battery cables for a hardwired install. Call us at (303) 876-7654 with your setup and we'll make sure you order everything you need in one go.
2kWh or 5kWh?
Same chemistry, same BMS, same warranty — the decision is about how much storage you need now and how much room you have for it.
Size
Capacity
Best For
2 kWh
2048Wh — 40Ah at 48V. Up to 6kWh with three in parallel
Vans, small campers and tight installations, or adding a modest amount of storage to an existing 2kWh bank
5 kWh
5120Wh — 100Ah at 48V. Up to 15kWh with three in parallel
RVs, cabins, workshops and off-grid homes — and the only route to a 15kWh bank on a single Power Hub
Batteries have to match within a bank — you can't mix 2kWh and 5kWh units on the same busbar. If you already own one size, that's the size to add. Call us at (303) 876-7654 if you're not sure what you have.

EcoFlow LFP Battery for 48V Systems — 2kWh and 5kWh: Frequently Asked Questions
Will this work as a standalone battery, or do I need a Power Hub?
It's designed as part of EcoFlow's 48V Power Kits system, communicating with the Power Hub over CAN bus for charge control and monitoring. It isn't a general-purpose 48V battery you drop into any inverter setup — the BMS expects to talk to compatible hardware. If you're building around third-party equipment, call us at (303) 876-7654 first and we'll tell you honestly whether this is the right battery for you.
What does auto-heating actually do?
Lithium cells are damaged by charging below freezing, so most batteries simply block charging when they're cold. This one uses some of its own energy to warm the cells first, which means it will accept a charge at ambient temperatures down to −4°F. If your batteries live in an unheated garage, a winter cabin, or a van you use in the shoulder seasons, that's the difference between a system that works in February and one that doesn't.
How many can I connect together?
Up to three in parallel per Power Hub, joined with the Terminal Busbar. That gives you 6kWh with the 2kWh battery or 15kWh with the 5kWh battery. All batteries in a bank need to be the same size.
Can I add a battery to a system that's already running?
Yes — these are hot-swap enabled, so you don't need to take the system offline to add or replace one. That's genuinely useful if the system is doing something important, like keeping a fridge or a medical device running.
How long will it last?
EcoFlow rates it for up to 3500 cycles at 80% depth of discharge, which is roughly ten years of cycling it daily. LFP chemistry is chosen for exactly this: it trades a little energy density for a long, stable service life and much better thermal behaviour than other lithium chemistries.
Can I mount it on its side or on a wall?
The box includes a wall mounting clamp, a bracket, and a strap, so wall and floor mounting are both supported. Follow the orientation guidance in the manual — and in a vehicle, mount it properly rather than letting it sit loose, because a battery this heavy becomes dangerous in a sudden stop.
What's included, and what will I still need?
You get the battery plus the wall clamp, mounting bracket and strap. You'll separately need the Terminal Busbar if you're paralleling batteries, and the appropriate battery cables for your install. We can put that list together for you over the phone.
Is it safe to install inside a living space?
LFP is the safest of the common lithium chemistries, and the BMS protects against overcharge, over-discharge, short circuit and thermal problems. It's routinely installed inside RVs and homes. Follow the manual's clearance and ventilation guidance, keep it dry, and have the AC side of any installation handled by a qualified installer.
What warranty comes with it?
Five years from EcoFlow. Cables and accessories carry a 12-month warranty. We're an authorized dealer, so claims go through EcoFlow's normal process with our support behind them.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and our Price Match Guarantee applies — if you find this battery cheaper at another authorized dealer, call us at (303) 876-7654 before you order and we'll take care of it.
