Unlike standard deep-cycle lithium batteries that may trip their BMS during engine starting, the Epoch 12V 300Ah Dual Purpose Pro Series is engineered for cranking and deep-cycle service. It delivers up to 1,000A of peak discharge for 5 seconds and 800A for 10 seconds. Epoch specifically calls out compatibility with Mercury 250 hp motors and other leading outboard brands when the electrical system is properly matched.

The purpose of this dual purpose marine battery is to combine high-surge cranking output with 300Ah of deep-cycle house capacity. You can run fish finders, livewell pumps, bilge pumps, lighting, marine audio, refrigeration, and other 12V loads while still retaining high-amp starting capability when the system is designed correctly.\u003c\/p\u003e\n    \u003c\/details\u003e\u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #ED1B4A; border-radius:10px; padding:18px;\"\u003e\n      \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003eWill this fit in my current Group 8D marine battery tray?\u003c\/summary\u003e\n      \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003eYes, this battery is designed around a Group 8D marine battery footprint. Epoch lists the dimensions as 19.70 in L × 10.5 in W × 9.75 in H. If you currently run a Group 8D lead-acid or AGM battery, this lithium upgrade is intended to fit the same class of tray, but you should still verify tray dimensions, hold-downs, lid clearance, terminal access, and cable reach before ordering.\u003c\/p\u003e\n    \u003c\/details\u003e\u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #2E91E5; border-radius:10px; padding:18px;\"\u003e\n      \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003eHow much weight will I save on my boat?\u003c\/summary\u003e\n      \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003eThe Epoch 12V 300Ah Group 8D lithium battery weighs 81 lbs. Many traditional Group 8D lead-acid or AGM batteries weigh roughly 130 to 160 lbs, so switching to this battery can cut battery weight dramatically while increasing usable capacity. Less stern weight can help improve boat balance, hole shot, draft, and fuel efficiency depending on the vessel.\u003c\/p\u003e\n    \u003c\/details\u003e\u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #5EBB46; border-radius:10px; padding:18px;\"\u003e\n      \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003eCan I wire these batteries together for even more power?\u003c\/summary\u003e\n      \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003eYes.
