Trolling Motor Lithium Batteries

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

Overview

CMX Battery 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.

Key specifications

Specification	Value	Why it matters
Voltage	12V / 24V / 36V	Matches the motor.
Discharge	High continuous + surge	Full-throttle rated.
Weight	Light for boat payload	LiFePO4 advantage.
BMS	Integrated, high-discharge	Protects without sag.
Runtime	Deep DoD for long days	80–90% usable.

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 CMX Battery

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.
