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.

Warranty

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. Commercial or professional use is covered by your local statutory warranty instead.
