ePropulsion E100 48V LiFePO4 Battery (5120Wh, IP67)

The ePropulsion E100 is a high-capacity LiFePO₄ (lithium iron phosphate) battery built specifically for electric boating. With 5,120 Wh (100 Ah at 51.2 V) on tap and an all-metal, IP67-rated housing, it delivers serious range in a compact, low-profile case that drops neatly under a seat or into tight storage. Rated for 3,000 cycles at 80% state of health, it's a clean, low-maintenance power source designed to outlast traditional lead-acid banks by a wide margin.

Key Features

• 5,120 Wh / 100 Ah capacity — high-density LiFePO₄ power for longer days on the water.
• Flexible voltage configuration — runs 48V ePropulsion motors (1–6 kW: Spirit, Navy, Pod Drive). Two batteries in series step up to a 96V system for X12, P12, and the 1–10 kW motors.
• Built to take a beating — all-metal housing is impact-resistant, drop-proof, and weather-resistant with a full IP67 waterproof rating.
• Compact footprint — just 240 mm tall, so it fits where larger banks won't.
• Built-in display — real-time state of charge, voltage, current, and alarm status, with integration for third-party gateways.
• Intelligent BMS — onboard battery management system for safe, stable operation.
• 3,000 cycles @ 80% SoH — long service life that reduces replacement frequency.

Specifications

Charging & Scalability

• Scalable banks — up to 16 batteries in parallel for 48V systems. For 96V, connect two in series (note: parallel connection is not available once batteries are in series).
• 1C fast charging — with two E-Series chargers, a single battery charges in roughly 2.6 hours on 220V, or about 4.3 hours on 110V.

Compatibility

The E100 pairs with ePropulsion Spirit 1.0 Evo / Plus, Spirit 2, Navy 3.0 / 6.0 Evo, and Pod Drive 1.0 / 3.0 / 6.0 Evo motors out of the box. In a two-battery 96V configuration it also powers the X12, Pod Drive 12 eSSA, and I-10 inboard. Charge it with the ePropulsion E-Series (25A) or G-Series (16A) chargers.

The E100 is covered by ePropulsion's 24-month limited warranty (from delivery to the first end customer) against defects in materials and workmanship under normal recreational use with proper installation and maintenance.
