UL1973 Certified · UL9540A Tested · CEC & SGIP Listed

RUiXU RX-LFP48100-H Self-Heating 19" Server Rack Mounted 3U Module

The RUiXU RX-LFP48100-H is the self-heating version of RUiXU's 48V, 100Ah (5,120Wh) LiFePO4 rack battery — built for installs where the battery bank itself is exposed to cold, like unheated outbuildings, cabinets, or outdoor equipment enclosures. Built-in heater pads draw power from the charger itself and let the module safely charge at temperatures down to -20°C (-4°F), where a standard lithium battery would refuse to charge at all.

Aside from the cold-weather charging, it's the same rack-ready module: 19-inch, 3U form factor, up to 32 units in parallel for a 5kWh-160kWh bank, and DIP-switch setup for RS485 baud rate and inverter protocol. Renewable Outdoors is an authorized RUiXU dealer, and every RX-LFP48100-H we sell is backed by RUiXU's 10-year limited warranty. Don't need cold-weather charging? See the standard RX-LFP48100.

Why the RX-LFP48100-H Stands Out

Charges Down to -20°C (-4°F)

Built-in heater pads draw power from the charger itself, so the module can safely accept a charge in cold conditions that would shut a standard lithium battery down.

Standard 19" 3U Rack Fit

Same rack-ready footprint as the standard RX-LFP48100 — drops straight into a 19-inch server rack with no custom enclosure.

Scales to 160kWh

Connect up to 32 modules in parallel — from a single 5.12kWh unit to a 160kWh bank — without an external controller.

Wide Inverter Compatibility

Canbus and RS485 support covers most major brands, including Victron, SMA, Sol-Ark, Solis, Deye, Growatt, and Sunsynk.

Simple DIP-Switch Setup

Set the RS485 baud rate and choose your inverter protocol with onboard DIP address switches — no separate software required.

Ready to Install

Ships with a patch cable, ground cable, and a set of parallel 4AWG cables per battery, so you can rack it and wire it the same day.

Cycle life, recommended charge current, and operating/storage temperature weren't listed in text-extractable form on RUiXU's manufacturer page for this specific module, so those four figures come from Renewable Outdoors' own first-party product listing rather than an independently confirmed manufacturer source. Everything else on this table (voltage, capacity, energy, dimensions, weight, certifications, self-heating rating) was verified directly against RUiXU's manufacturer page. We couldn't find a direct manufacturer-hosted spec sheet/manual PDF for this module either — only third-party mirrors, which we don't link to.

10-Year Warranty

Every RX-LFP48100-H we sell is backed by RUiXU's full 10-year limited manufacturer warranty.

RUiXU RX-LFP48100-H: Frequently Asked Questions

How is this different from the standard RX-LFP48100?
The RX-LFP48100-H has the exact same voltage, capacity, dimensions, and rack form factor as the standard RX-LFP48100 — the difference is built-in heater pads that let it safely charge at temperatures down to -20°C (-4°F). Choose the -H version if the battery bank itself will be exposed to cold, like an unheated outbuilding or outdoor enclosure.
How cold can it get before this battery stops charging?
The RX-LFP48100-H can safely charge at temperatures as low as -20°C (-4°F) using a standard charger or solar charger. Its heater pads draw power from the charger itself to keep the cells warm enough to accept a charge safely.
Will this fit in my server rack?
Yes. The RX-LFP48100-H is a standard 3U module sized for any 19-inch server rack, at 19" × 18.1" × 5.23".
How many modules can I connect together?
Up to 32 RX-LFP48100-H modules can be connected in parallel without an external controller, scaling from a single 5.12kWh module up to a 160kWh bank.
What inverters is it compatible with?
It communicates over Canbus or RS485 and is compatible with most major inverter brands, including Victron, SMA, Sol-Ark, Solis, Deye, Growatt, Goodwe, Sunsynk, and Schneider, among others.
What's the recommended charge current and cycle life?
RUiXU rates the RX-LFP48100-H for a recommended charge current of 50A and a cycle life of 6,000+ cycles at 90% depth of discharge.
What certifications does it carry?
The RX-LFP48100-H is UL1973 certified and UL9540A tested, and is listed for California's CEC and SGIP incentive programs.
