A trolling motor wants sustained high current — EGbatt builds LiFePO4 packs with the discharge rating and light weight to run all day at full throttle.

Overview

EGbatt trolling-motor batteries are 12V/24V/36V LiFePO4 packs specified for the high, sustained discharge a trolling motor draws, with an integrated BMS that protects the pack without choking the throttle. LiFePO4’s weight advantage matters on a boat, and its flat discharge curve holds voltage high deep into the cycle, so the motor keeps its punch where lead-acid would sag. We match voltage and Ah to the motor’s draw and runtime you need, and spec the charger to LFP.

Typical applications

  • Bow and transom trolling: Sustained draw.
  • Fishing boats: All-day runtime.
  • Kayak and small craft: Lightweight pack.
  • Marine house + trolling: Paired banks.

How to specify & buying guide

  • Match pack voltage to the motor (12/24/36V) and Ah to desired runtime at its draw.
  • Confirm the BMS continuous/surge current covers full throttle.
  • Use an LiFePO4 charger; lead-acid overcharges LFP.
  • Secure the pack — LFP is smaller/lighter than the lead-acid it replaces.

Engineering & manufacturing at EGbatt

Portable and specialty packs are built for shock, dust and temperature swing. We select cells and BMS for high-discharge and fast-recharge profiles, seal the enclosure to the right IP rating, and validate the pack through drop, vibration and thermal cycling.

Certifications & compliance

  • UN38.3 — Mandatory lithium battery transport test (altitude, thermal, vibration, shock, external short). Required for any cross-border shipment.
  • IEC62619 — International safety standard for industrial Li-ion cells and batteries; expected by EU and most APAC buyers.
  • CE — EU declaration of conformity for the applicable directives.
  • RoHS — Restriction of hazardous substances in the battery and BMS.
  • IP67 — Dust-tight and immersion resistant up to 1 m — for harsh mobile or marine use.

Frequently asked questions

How long will it run my motor?

From Ah ÷ motor draw at the throttle you use; we size from the motor spec.

Will voltage sag at full throttle?

LiFePO4 holds voltage deep into discharge; the BMS protects without choking power.

What voltage do I need?

Whatever the motor is built for — 12, 24 or 36V.

Is it lighter than lead-acid?

Roughly a quarter the weight for the same Ah.
