E&J LiFePO4 Rechargeable Lithium Deep Cycle Battery 12v 250Ah

Smart, clean, and incredibly light

The E&J LiFePO4 Rechargeable Lithium Deep Cycle Battery belongs to a new generation of lithium iron phosphate batteries designed to be ultra-light, heavy-duty, long term replacements for older environmentally-harmful batteries. LiFePO4 batteries are designed for reliable safety, long life, low environmental impact, and efficient charging/discharging performance. It's one of the best options for smart, clean power.

E&J uses no heavy metals in making this premium green power source. Their batteries have an extremely long life yielding up to 2000 cycles, with low internal resistance and extreme stability. Plus, each battery is maintenance-free, has no memory effect, and can withstand large fluctuations in temperature.

E&J LiFePO4 Rechargeable Lithium Deep Cycle Battery Features:

• Long cycle life - lasts up to 10 times longer than lead acid (SLA) batteries
• More usable capacity - use up to 100% of total stored energy (SLA approx. 50%)
• Fast charging - up to 10 times faster than SLA batteries
• Ultra-low self-discharge - less than 2% per month
• BMS protection - protects against overcharge, ensures maximum longevity
• Increased flexibility - connect up to 4 E&J lithium batteries in series
• Lightweight - about half the weight of an equivalent SLA battery
• Easy installation - drop-in replacement for deep-cycle SLA battery
• Environmentally friendly - non-toxic contains no acid can be installed in any direction
