Product Hightlights
• K2 Energy's 12v 11ah LiFePO4 battery is powered by high-capacity lithium iron phosphate cells, ensuring the highest level of safety during operation and superior performance.
• This battery features an ultra-lightweight case design, making it remarkably easy to move compared to traditional sealed lead-acid batteries.
• Designed for durability and longevity, K2's 12v 11ah battery includes cell balancing for consistent discharge and a standby life of 5-10 years
• 3000+ cycles - 10x the cycle life of sealed lead acid batteries. SLA batteries of similar size and spec typically last 500 cycles.
• Splash & Dust Resistant Case - For marine use please use a water tight case for full protection
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
While LiFePO4 batteries may have a higher upfront cost than lead-acid batteries, they’re often the more cost-effective option in the long run. They offer longer lifespans and require less maintenance, which can ultimately save you money over time.
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.
