UP TO 80% MORE CAPACITY THAN COMPETING LiFePO4 BATTERIES
Available in Three Convenient Form Factors
POWER YOUR ADVENTURES...
With the highest capacity LiFePO4 Deep Cycle batteries Available!
Our Deep Cycle batteries are LiFePO4, which means they're extremely safe, eco-friendly, and reliable. All Ohmmu batteries use prismatic cells, significantly increasing their durability and storage capacity. Compared to lead acid, LiFePO4 batteries provide ~2x the Power at 1/3 the weight and last 10x Longer.
Upgrade your RV, boat, overlander, van, or skoolie today and save time, money, weight, and space - the more batteries you buy, the bigger the savings!

ADVANTAGES OF LiFePO4 BATTERIES VS LEAD ACID (SLA)
Battery Life Span (Number of Cycles)
LiFePO4 Battery: 5,000+
Lead-acid Battery: 500 or Less
Life expectancy is one of the biggest advantages of LiFePO4. Our batteries are rated to last 5,000+ cycles, which equates to 10 years or more depending on usage.
Even after their optimum lifespan, our batteries continue to function at ~70% capacity. Better still, you can safely discharge our batteries past 80% without issue, whereas lead acid batteries are at risk of releasing hazardous gases and/or presenting fire and explosion risks if charged incorrectly, overcharged, or discharged past 50%.
DEPTH OF DISCHARGE (DOD) FOR RATED CAPACITY
LiFePO4 Battery: 100% of Capacity
Lead-acid Battery: 50% of Capacity
LiFePO4 batteries provide 100% of their rated capacity regardless of discharge rate. Lead acid batteries should only be discharged to 50% state of charge (SoC), meaning its usable capacity is only half of its rated capacity. For example, if you have a 100Ah lead acid battery, you should only use 50Ah of energy before recharging.
CHARGING TIME, EFFICIENCY & STORAGE
LiFePO4 Battery: 4x Faster, Highly Efficient
Lead-acid Battery: Slow Charge, Inefficient
LiFePO4 batteries charge 4-6x faster than sealed lead-acid (SLA), which are notoriously slow and have a lower efficiency energy conversion (~80%). Faster charge times and 97%+ energy conversion for LiFePO4 batteries means less time running your generator or searching for the sun for your solar panels.
LiFePO4 batteries don't require active maintenance to extend their service life and have an extremely low self-discharge rate when not in use (1-3% per month). In contrast, lead acid batteries have a high self-discharge rate (15-30% per month) and require float / trickle charging in storage to avoid sulfation and battery life loss / failure.
BATTERY WEIGHT COMPARISON
LiFePO4 Battery: 1/3rd the Weight of SLA
Lead-acid Battery: 3x Heavier than LiFePO4
LiFePO4 batteries have a higher power density than lead-acid, allowing them to store up to 50% more energy while weighing ~66% less. This translates to easier installations, increased performance / gas mileage, etc.
