INSiGHT by MaxCell Lithium
Battery Intelligence Platform CAN Bus · Cloud · Desktop · Mobile

INSiGHT is MaxCell's proprietary battery monitoring and testing application — available on desktop and mobile. It connects to your battery packs via CAN bus, logs every session to the cloud, and gives field engineers and office teams the same live data picture.

Step 1
Setup
Connect battery, register in INSiGHT, create your Job DB, run Continuity & Depassivation pre-run tests.
Step 2
Deploy
Go downhole. INSiGHT logs live voltage, current, temperature, and shock continuously via CAN bus.
Step 3
Dump
Pull the run. DATA DUMP retrieves all session data from onboard flash memory to your PC automatically.
Step 4
Evaluate
Analyze every channel in the Graph tab. Export CSV or HEX for customer reports, engineering review, or archiving.
4×
Battery packs monitored simultaneously from one session
0
Surprise downhole failures — pre-run tests catch weak packs first
100%
Data traceability — every volt, amp, and shock event logged
Live
Field intelligence — battery state always visible via CAN bus

INSiGHT Graph View — multi-channel downhole data
Live Telemetry
Voltage & Current

Real-time pack voltage, rated voltage, session min/max/avg, current out and max current — all monitored live over CAN.

Mechanical Data
Shock & Vibration

Lateral XY and Axial Z shock in g-force, shock event counts, stick-slip detection, and all-time maximums recorded per session.

Capacity Tracking
Amp-Hour & Runtime

Gauge-style capacity display, amp-hours consumed, and hours-remaining estimation — always current with live RTC timestamp.

Thermal Monitoring
Temperature Logging

Continuous temperature recording with session min/max and all-time peak tracking — critical for high-temperature downhole applications.

Multi-Channel Graphs
Time-Series Analysis

Filter and display Voltage, Current, Power, Temperature, Motion, Rotation, or Shock channels independently across full run sessions.

Automated QA
Test Box Suite

Run continuity checks (8-channel sweep), depassivation tests with live telemetry, and export full test logs as CSV for records.

Job Management
Well & Rig Tracking

Tag every session with job name, operator, well name, rig name, and segment data — keeping batteries tied to their actual field history.

Fleet Monitoring
Multi-Battery View

Monitor up to 4 battery packs simultaneously from a single INSiGHT session, with individual live data views for each unit.

Desktop App

Full-featured Windows application with dark and light themes — connect directly to packs via USB/CAN adapter for bench testing or surface monitoring.

Mobile App

Download INSiGHT on your phone or tablet and access live data, job history, and session logs — anywhere there's a connection.

58,000+ Samples Per Session

High-resolution data capture stores tens of thousands of measurement samples per run, giving post-run analysis the resolution it needs.

Cloud-Backed Sessions

Session data uploads to secure cloud storage automatically — accessible from any device, with HEX import/export for field data retrieval.

🛡
Avoid Costly Failures
Pre-run Continuity and Depassivation tests catch weak or de-activated batteries before they go in the hole — saving round-trip costs and lost rig time.
📊
Prove Performance to Operators
Operators increasingly demand battery performance data. INSiGHT exports job-level reports showing voltage curves, thermal performance, and shock history — turning your data into a competitive differentiator.
🔧
Protect Your MWD & BHA Tools
Shock & vibration logging creates a documented record of every g-force event. When a tool comes back damaged, INSiGHT shows exactly what happened downhole.

End-to-End Capability

From Concept to Completion —
We Own Every Step

MaxCell manages the full battery development lifecycle in-house. Whether you're bringing a new tool to market or replacing a legacy pack, our team covers every phase — so you work with one partner from first engineering call to final disposal.

🔬
Phase 01
Application
Tool spec review, voltage/current analysis, environment profiling, and chemistry selection for your exact use case.
📐
Phase 02
Engineering
Cell selection, pack architecture, thermal management, mechanical layout, and INSiGHT integration planning.
⚙️
Phase 03
Design
Prototype development, electrical schematics, enclosure drawings, and validation testing before production approval.
🏭
Phase 04
Manufacturing
Precision assembly, multi-point QC, INSiGHT pre-ship testing, and full traceability records on every pack that ships.
♻️
Phase 05
Recycling
Spent primary lithium battery return and responsible recycling — compliant, documented, and handled at no extra logistics burden to you.

One Partner.
Zero Hand-Offs.

Most suppliers hand off after the sale. MaxCell stays engaged — from the first engineering conversation through every run report in INSiGHT and the eventual recycling of the spent pack. That continuity is what keeps our packs performing run after run, and what keeps your tools in the ground instead of on the shop floor.

Cell-Agnostic
Access to all major cell manufacturers — we spec the best chemistry for your tool, not the one we happen to stock.
INSiGHT-Ready
Every pack we manufacture is compatible with INSiGHT monitoring — pre-run testing through post-run data export.
Oilfield-First
Built for MWD, LWD, and downhole tool demands — shock-qualified, high-temp rated, and field-proven.
Fully Traceable
Serial-number-level records tie every pack to its build spec, test history, and field sessions in INSiGHT's job database.

Our Difference

More Than a Battery Supplier

We combine hardware precision with software intelligence to give you visibility into every pack we ship — from factory test to final run report.

01
Cell-Agnostic Engineering

No allegiance to a single cell manufacturer means we select the chemistry and supplier that best fits your application — not what's convenient for us.

02
O&G Focus, Broad Capability

Our primary focus is oil and gas, but our engineering capability extends to any project that demands reliable downhole power. We support surface and subsurface applications across sectors.

03
INSiGHT: Data That Travels With the Pack

Every battery we ship is INSiGHT-compatible. That means continuity-tested, depassivation-verified, and fully traceable — with cloud-stored session history from day one.

04
US-Based, Rapid Response

Located in Porter, TX. When the rig calls, we're reachable. No long international lead times, no language barriers, no black box supply chains.
