Key features

• •The lifespan of LiFePO4 (lithium) batteries is 8 to 10 times longer than that of regular lead-acid batteries (2000~5000 cycles vs 300-500 cycles). The usable capacity also doubles compared to that of a lead-acid battery while the weight is 30% less thanks to its significantly higher energy density. Without any memory effect, the lithium battery can hold a charge better while not in use and will not lose capacity due to the previous discharge state.
• •Built-In BMS & Convenience & Maintenance Free -This marine lithium deep cycle battery is designed to meet your high performance demands, featuring a robust Battery Management System (BMS) that safeguards against overcharge, over-discharge, over-current, and short circuits. Its excellent self-discharge rate ensures reliability over extended periods. Engineered with a built-in high temp cut-off to prevent charging over 122 °F (50 °C), this lithium ion deep cycle battery 12V offers enhanced safety compared to traditional lead acid batteries.
• •The Group Size BCI 27 lithium-ion battery features dimensions of L- 12 x W- 6.81 x H- 7.87 inches and weighs 18.8 lbs, with a voltage of 12 and 70 Amp Hours. Its Chemistry is Lithium-Iron Phosphate (LiFePO4), offering Cold Cranking Amps (CCA) of 900. Lightweight and maintenance-free, it excels in both outdoor and indoor applications, providing long life and high CCA performance for marine and starting battery requirements.
• •Dual Terminal Posts: Allows for easy and versatile connectivity, compatible with various marine setups without needing adapters.
• •5 Year Full Replacement Warranty
