3.84kWh LiFePO4 Battery Pack 12.8V — Deep Cycle Solar Storage, 6000+ Cycles

The largest of the 12.8 V range, this 300 Ah pack suits installations that want 12 V simplicity with real endurance — a weekend away without recharging, or a full night of essential loads. Where it fits best Extended off-grid weekends in a camper or boat Backup for essential 12 V loads through long outages Small solar systems preferring one large battery over several small ones Questions buyers ask Is one large battery better than several small ones? A single pack avoids balance and wiring complexity. Several smaller units give redundancy and easier handling — at 300 Ah this pack is heavy for one person to move. What discharge current can it sustain? 50 A recommended continuously with 100 A maximum. Check your inverter's draw against those figures before sizing loads.
