Battle Born 75Ah 12V Group 24 LiFePO4 Battery | Standard or Heated

Lithium for the small tray. The Battle Born BB1275 fits a Group 24 box — the size on most travel trailers and small campers — and gives you 75 Ah of fully usable capacity, more than a 100 Ah lead-acid Group 24 actually delivers.

Versions

• BB1275 — standard 75 Ah
• BB1275H — heated for sub-freezing charging

⚠️ Charging and Cold Weather

Lithium needs a lithium-compatible charge profile — verify your converter, inverter/charger, and solar controller support LiFePO4 (14.2–14.6 V bulk). Standard batteries will not accept a charge below 25°F; the H heated versions warm themselves from the charge source so they can charge in freezing weather. I smart versions add Dragonfly IntelLigence for Bluetooth monitoring and connect to the Battle Born HUB.
