48V (51.2V) Marine BSLBatt Pro 100ah 5.12KW Lithium Battery – B-LFP48-100

Power your boat and many other off grid systems with a lithium battery that’s built for real onboard loads — and designed to integrate cleanly with Victron systems. The BSLBATT B‑LFP48‑100 is a 51.2V 100Ah (5.12kWh) LiFePO4 battery engineered as a modern replacement for lead-acid, GEL or AGM, giving you dependable deep‑cycle performance with far less maintenance.

With Victron plug‑and‑play support via RS485/CAN, it’s ideal for marine house banks running inverters, chargers and solar. You get stable energy for fridges, lighting, navigation electronics, pumps and onboard comforts — plus the confidence of an intelligent BMS with built‑in protection against overcharge, over‑discharge, over‑current and short circuit.

Designed for demanding environments, the B‑LFP48‑100 operates across a wide temperature range and delivers strong output when you need it most: 100A continuous discharge with 200A peak (10 seconds) for handling short surges. It’s also built for longevity, rated at ≥3500 cycles at 80% DoD, making it a smart long‑term upgrade for boat owners who want reliable power without the constant upkeep of traditional batteries.
