RELiON RB20-LT LiFePO4 Battery 12.8V 20Ah — Low Temperature Lithium for Cold Climate Marine, RV & Off-Grid Applications

The RELiON RB20-LT is a 12.8V 20Ah (256Wh) LiFePO4 (lithium iron phosphate) battery engineered with built-in low temperature charging protection — a critical feature for Canadian winters and cold climate applications where standard lithium batteries cannot safely charge below 0°C. The "LT" designation means the battery's integrated BMS automatically prevents charging in sub-zero temperatures, protecting cell integrity and extending battery life in cold environments.

At just 3.0 kg — a fraction of the weight of an equivalent AGM battery — the RB20-LT delivers superior energy density, longer cycle life, and consistent performance across a wide temperature range. Backed by an industry-leading 36-month full warranty with 10-year prorated coverage from RELiON.

Key Features

  • 12.8V / 20Ah / 256Wh — compact lithium power for marine, RV, and off-grid applications
  • Low temperature (LT) protection — built-in BMS prevents charging below 0°C to protect cells in Canadian winters
  • LiFePO4 chemistry — safest lithium chemistry; no thermal runaway risk; 2000+ cycle life
  • Lightweight — only 3.0 kg vs. 6–8 kg for equivalent AGM batteries
  • Drop-in replacement — 12.8V nominal voltage compatible with 12V systems
  • Integrated BMS — protects against overcharge, over-discharge, short circuit, and temperature extremes
  • 36-month full warranty / 10-year prorated — industry-leading coverage from RELiON
