Product Benefits
Safe Battery Design
K2 LiFePO4 chemistry batteries are less likely to leak or rupture, and they’re not prone to thermal runaway, which can cause a fire or explosion. K2 LiFePO4 batteries are more environmentally friendly than sealed lead-acid batteries, as they don’t contain any toxic heavy metals.
Lower Total Cost of Ownership
LiFePO4 batteries require minimal maintenance, with no need for regular maintenance. Lead Acid batteries require regular maintenance with the frequent need for adding distilled water and replacing corroded terminals. Lead-acid batteries develop a memory effect over time, which means they can quickly lose their capacity to hold a charge. Lithium batteries hold their charge longer, more consistently, and have a much longer overall lifespan.
No Maintenance & Longer Lifespan
LiFePO4 batteries require minimal maintenance, with no need for regular maintenance. Lead Acid batteries require regular maintenance with the frequent need for adding distilled water and replacing corroded terminals. Lead-acid batteries develop a memory effect over time, which means they can quickly lose their capacity to hold a charge. Lithium batteries hold their charge longer, more consistently, and have a much longer overall lifespan.
Lightweight Design
Ultra Lightweight design – over 50% weight savings compared to similar capacity SLA batteries. Remarkably easy to move and more space efficient.
Advanced Battery Management System (BMS)
Our BMS system safeguards your battery with features such as low voltage cutoff, high voltage cutoff, overcharge protection, short circuit protection and high/low-temperature protection-preventing damage from extreme conditions. Our K2 Energy BMS has an auto-balancing cell function to actively maintain consistent voltage and state of charge across all LiFePO4 cells to extend battery lifespan.
Outdoor & Industrial Use
K2 Energy’s 12V 11Ah LiFePO4 battery is engineered for rugged outdoor applications like fish finders, fishing kayaks, boating electronics, and ice fishing augers. This pack also has many industrial uses such as robotics, solar powered lights, backup power systems and 12v SLA replacement battery.
