Dual-Purpose Performance: Deliver a massive 1200 Cold Cranking Amps (CCA) to effortlessly start your marine engines while reserving 160Ah of deep-cycle capacity for house electronics. Massive Weight Reduction: Weighing only 38 lbs, this lithium battery shaves substantial weight off your vessel compared to traditional lead-acid equivalents, instantly improving speed and fuel efficiency. Intelligent Safety: Built with an Advanced Battery Management System (BMS) equipped with active cell balancing, low-voltage disconnect, and a reliable low-temperature charging cutoff. Proven Longevity: Engineered to provide 5,000+ cycles at 80% Depth of Discharge, maximizing your return on investment over years of harsh marine use. What This Upgrade Fixes Eliminate the anxiety of a dead starter battery after running trolling motors and electronics all day long. This upgrade ends the routine maintenance, heavy lifting, and frequent replacements associated with traditional lead-acid marine batteries. It also solves the problem of underperforming electronics caused by voltage sag—our LiFePO4 chemistry holds a steady voltage until completely depleted. What's Included [FILL: WHAT'S INCLUDED] Compatibility This is a universal flat-fit design manufactured in the standard Group 31 form factor, meaning it works as a direct drop-in replacement for existing Group 31 marine or RV battery setups. It operates seamlessly with standard 12V alternators and marine charging systems supporting a 14.2V - 14.6V charging profile. Ideal for marine house power, engine cranking, RV house banks, trolling motors, and solar storage applications. Installation Estimated Time: 15–30 minutes Difficulty: Beginner Tools Needed: Basic socket set or wrench to disconnect the old battery and torque your existing ring terminals onto the new battery posts.

Yes. Unlike standard deep-cycle lithium batteries, this unit pushes 1200 CCA designed specifically for engine cranking, alongside providing 160Ah of true deep-cycle energy storage for motors and electronics. Will this fit in my existing battery tray? Yes, this is built precisely to a Group 31 blueprint. As long as your current setup accommodates a standard Group 31 battery, it is a simple drop-in swap. Will the battery be damaged if I charge it in freezing weather? No. The integrated BMS includes a low-temperature charging cutoff. If the internal temperature drops below 0°C (32°F), it automatically prevents a charge to protect the lithium cells from permanent damage.","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/160-ah-blue-max-marine-lifepo4-battery-battery-main.jpg?v=1788994180","href":"/product/160-ah-blue-max-marine-lifepo4-battery-battery.html","buy_url":"https://xyjpsn-3p.myshopify.com/products/160-ah-blue-max-marine-lifepo4-battery-battery","buy_url_source":"shops.shop_domain + product.handle","seller_name":"xyjpsn-3p.myshopify.com","seller_url":"https://xyjpsn-3p.myshopify.com/","return_policy_url":"https://xyjpsn-3p.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/160-ah-blue-max-marine-lifepo4-battery-battery-main.jpg?v=1788994180","alt":null,"position":0}],"related":[{"handle":"12v-100ah-fleet-lithium-engine-starting-group-27","title":"12V 100ah Fleet Lithium Engine Starting (Group 27)","category":"12 Volt Lithium","price":"$289.25","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/12v-100ah-engine-starting-group-27-main.jpg?v=1788994172","sku":"FL13100","href":"/product/12v-100ah-fleet-lithium-engine-starting-group-27.html"},{"handle":"bluemax-marine-12v-200ah-lifepo4-deep-cycle-battery-group-27","title":"BlueMax Marine 12V 200Ah LiFePO4 Deep Cycle Battery (Group 27)","category":"12 Volt Lithium","price":"$337.35","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/bluemax-marine-12v-200ah-lifepo4-deep-cycle-battery-group-27-main.jpg?v=1788994176","sku":"BMDC12V200","href":"/product/bluemax-marine-12v-200ah-lifepo4-deep-cycle-battery-group-27.html"},{"handle":"105-ah-blue-max-marine-lifepo4-battery-battery","title":"BlueMax Marine 12V 105Ah LiFePO4 Battery (Group 24)","category":"12 Volt Lithium","price":"$251.55","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/105-ah-blue-max-marine-lifepo4-battery-battery-main.jpg?v=1788994224","sku":"BM12V105","href":"/product/105-ah-blue-max-marine-lifepo4-battery-battery.html"},{"handle":"200-ah-12v-blue-max-marine-lifepo4-battery-battery","title":"BlueMax Marine 12V 195Ah LiFePO4 Deep Cycle Battery (Group 27)","category":"12 Volt Lithium","price":"$337.35","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/bluemax-marine-12v-200ah-lifepo4-deep-cy-promo-1776812084846.png?v=1788994171","sku":"BMDC12V200","href":"/product/200-ah-12v-blue-max-marine-lifepo4-battery-battery.html"}]}}
