Deep Cycle Efficiency and Performance

The new BB8D may look like your everyday 8D
battery, but that is where the similarities end.
This 12V deep cycle battery is rated for 270Ah and
weighs roughly 80 lbs. That's over 50 lbs. lighter than
a standard lead-acid 8D. Utilizing the same stable
LiFePO4 chemical composition and built-in battery
management system (BMS) technology as our other
products, the BB8D is truly the biggest bang for your
The BB8D is perfect for large marine applications, or
for off-grid applications. This battery is capable of
being discharged to a 100% depth of discharge and
charges 5 times faster than lead-acid. With the BB8D,
the switch to lithium has never been easier.
Built to last 10 to 15 years and backed by an industry
leading 10-year warranty, at Battle Born Batteries we're
making battery anxiety a thing of the past.
