Overview

The RELiON RB52-LT is a 12V 52Ah LiFePO4 deep cycle battery designed for extreme temperature performance. It features an integrated heating element that activates at temperatures as low as -4°F (-20°C) to enable safe charging in sub-zero conditions, making it suitable for winter marine operations, off-grid solar systems in harsh weather, RVs, and remote backup power.

This battery delivers 640Wh of energy with a 50A continuous discharge rate and 100A peak discharge for 7.5 seconds. Its advanced Battery Management System (BMS) provides protection against overcharge, over-discharge, short circuits, and thermal extremes, while the IP67 waterproof enclosure ensures durability in tough environments. The RB52-LT offers a cycle life of over 3,500 cycles at 80% depth of discharge and comes with a 10-year limited warranty.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
