38.4V 32Ah LiFePO4 26650 Battery Pack with Smart BMS & Bluetooth for Field Test Equipment

A manufacturer of portable field-test instruments approached CM Batteries after equipment deployed across multiple climate zones showed inconsistent runtime, and field engineers had no way to check battery health without opening the enclosure. Because the equipment travels between hot desert sites and sub-zero mountain sites within the same testing season, the customer needed a 38.4V 32Ah LiFePO4 battery pack for field test equipment that performed reliably everywhere — and a way for technicians to check pack status without a screwdriver.

CM Batteries delivered a 38.4V 32Ah 12S10P LiFePO4 battery pack rated for -30°C to 60°C charging and -50°C to 60°C discharging, with an integrated smart BMS and Bluetooth interface so technicians can pull pack diagnostics directly from a phone in the field — backed by a 5-year warranty. It’s part of CM Batteries’ wider custom 26650 LiFePO4 battery pack range for wide-temperature, connected applications.

Field Test Equipment Customer Overview

The customer builds portable environmental and geotechnical test instruments used by survey crews and engineering contractors, with product testing and reliability validated through CM Batteries’ verification and validation process. Their equipment is deployed on short-term assignments across widely different climates, sometimes moving from one project site to another within the same week.

Because a battery-related failure in the field can delay an entire survey crew’s schedule, the customer needed both climate reliability and the ability to catch a degrading pack before it fails on-site, rather than after.

No Battery Health Monitoring in the Field

Technicians could only find out a pack was degrading once the instrument shut down mid-survey, with no earlier warning sign available.

CMB Solution:
Integrated a smart BMS with Bluetooth output, so technicians can check voltage and temperature status from a phone before starting a survey, without opening the case.

Multiple Battery Configurations for Different Climates

The same instrument model needed different battery configurations depending on whether it was deployed to a hot or a cold climate, complicating inventory and field support.

CMB Solution:
Delivered one wide-temperature LiFePO4 battery platform rated for industrial equipment,rated for -30°C to 60°C charge and -50°C to 60°C discharge, so a single SKU covers every deployment climate.

Battery Lifecycle Did Not Match Equipment Service Life

Field instruments are expected to stay in service for years, and the customer needed confidence in long-term battery support rather than a short commercial warranty.

CMB Solution:
Backed the pack with a 5-year warranty, aligning battery support with the instrument’s expected service life.

FAQs — 38.4V 32Ah Smart LiFePO4 Battery Pack

What data can the Bluetooth interface show?

The smart BMS can expose basic pack status such as voltage and temperature over Bluetooth. The exact data fields exposed to your app or device are defined during the project scoping phase based on your monitoring needs.

Can I get RS485 or CANBUS instead of Bluetooth?

Yes. CMB’s smart BMS platform supports Bluetooth, RS485, and CANBUS communication — the right choice depends on how your equipment’s existing monitoring system is built.

What does the 5-year warranty cover?

Exact warranty terms are set out in the project contract. Talk to CMB’s sales team when you request a quote to confirm the coverage that applies to your market.
