Inside the Pack
Take apart the battery from 22 electric cars and buses. See what each is made of and weigh recycling against reuse.
Valuing used packs? Talk to usTools and advice for batteries, energy storage, solar and recycling.
Teslin advises companies working on clean energy and critical minerals. We also build free tools on what is inside a battery, how a storage site runs, and the electrical basics.
New: Electrical Fundamentals is live
Tools
Battery storage, explained
A grid battery site in 3D. Open an enclosure down to the cells and see who maintains what.
Planning a storage site? Talk to us
Electrical Fundamentals
Volts, amps, AC and DC, and how a battery site protects itself. A refresher before a site visit or a technical meeting.

-
Advisory
Reuse or recycle? What is a used pack worth? Which storage setup suits a site? We work through the numbers with you and give a straight answer.
-
Modelling
Cost and value models built on your own numbers: what a used battery is worth, what can be recovered from it, what a storage site costs.
-
Project support
A second pair of eyes on your project: specs, vendor questions, and who maintains what.
What we work on
Batteries
What is inside an EV or storage battery, and what it is worth.
Energy storage
How grid batteries are built, wired, protected and kept running.
Solar
How panels connect to storage and to the buildings they power.
Recycling and second life
What a battery can do after the car, and what can be recovered at the end.
Critical minerals
The lithium, nickel, cobalt and graphite in batteries, and what they cost.
