Lithium Battery for Marine Trolling Motors
I have spent a good part of the last twelve years on the electrical side of small craft — bass boats in the south, aluminium skiffs in the Pacific Northwes…
Sodium-Ion Battery for Residential Solar Self-Consumption
I have spent the last decade specifying cells for UAV packs, telecom backup strings and, more recently, for the garage wall. In the last three years the q…
Battery Solution for Smart Metering and AMI Networks
When a utility wants to cut truck rolls by 80% and turn a 10-million-meter fleet into a remotely managed endpoint grid, every node becomes only as reliabl…
Semi-Solid State Battery Cold Start Performance
I have lost count of the number of cold-chamber mornings I have spent watching a battery pack that worked perfectly at 25°C collapse into a few hundred…
Home Energy Storage for Multi-Family Buildings
In fifteen years of designing stationary lithium battery systems, the projects I get called back to audit are almost never the single-family garage install…
Semi-Solid State Battery Fast Charge Capability and Limits
Pulling 4C out of a semi-solid state pack sounds like a spec sheet triumph until you watch a thin slice of anode under a reference electrode and see lithiu…
Home Energy Storage Payback Period Calculation Guide
After twenty years of sizing lithium battery systems, I have reviewed hundreds of payback spreadsheets submitted by distributors and homeowners, and I woul…
Lithium Battery Testing for Power Tools: Pulse-Current
In eleven years of designing and validating lithium battery packs for cordless tools, I have watched more projects fail at the validation bench than at the…
Battery Solution for Refrigerated Transport Units
Refrigerated transport has quietly become one of the most demanding environments a lithium battery can be asked to survive in. Over the past eleven years I…
Sodium-Ion Battery Design for Street Lights: Off-Grid
Twelve years into designing lithium battery packs for outdoor deployments, I assumed the first truly large sodium-ion fleet I would touch would be a contai…
