Choosing Battery Cycler Current Ranges for Lab Testing

October 27, 2026

When a lab starts looking for a battery tester, voltage and channel count usually come up first. Fair enough. But the part that quietly decides whether the data is clean or noisy is the current range — and how tightly the machine can hold it. Anyone who has put coin cells on a high-current channel knows the problem. The numbers appear, yet the resolution is coarse, the low-rate points look rough, and comparing early-cycle coulombic efficiency between batches becomes harder than it should be. The same thing happens in reverse: a machine that only goes to 100 mA starts feeling limiting the moment the work moves to 18650s or small

Why Two Identical Cells Give Different Results on Your Battery Cycler

October 21, 2026

A two percent capacity gap between two cells from the same batch looks like a materials problem. More often it is a measurement problem, and the first suspects are the fixtures, the sense wiring and the current range. Before you blame the chemistry, it is worth checking the test setup. Contact resistance is the usual suspect If the cycler measures voltage across the same two wires that carry the current, the voltage drop in the leads and fixtures is added to the cell voltage. At high currents this shifts the charge cutoff and discharge cutoff, so the cell reaches its limits early or late. A four-wire (Kelvin) connection, with separate

From Low-Altitude Economy Growth to Flight Safety Certification: The Underlying Logic of eVTOL Battery Testing

October 20, 2026

Executive Summary The low-altitude economy and electric vertical takeoff and landing (eVTOL) aircraft are rapidly transitioning from conceptual prototypes to commercial flight certification and fleet deployment. While high gravimetric energy density (Wh/kg) dominates industry headlines, real-world flight operations demand an uncompromising balance between dynamic high-rate power output, ultra-fast charging, thermal containment, and cell-to-cell consistency. For aviation battery developers, cell manufacturers, and eVTOL OEMs, rigorous high-power battery testing and consistency validation are the bedrock of operational safety and commercial viability.   Part 1: Industry Trends – The Rise of Low-Altitude Aviation and the Demands on Flight-Grade Batteries Recent industry reports and policy updates highlight accelerated momentum in the low-altitude economy.

Why is the Discharge Min Voltage of a Battery Tester So Critical? How to select from 1V, 0V and -5V discharge min voltage?

October 20, 2026

Why is the Discharge Min Voltage of a Battery Tester So Critical? How to select from 1V, 0V and -5V discharge min voltage? When selecting battery tester, most buyers focus heavily on maximum voltage and rated current. However, the discharge min voltage is often overlooked — yet it is a fundamental hardware constraint defined by the electrochemistry of different battery materials. Lithium iron phosphate, NMC ternary lithium, sodium-ion batteries and aqueous batteries each have distinct discharge cut-off requirements. Using a tester with an insufficiently low voltage limit will truncate discharge curves, produce incorrect capacity readings and even cause unintended over-discharge damage to cells.

Solid State Battery Roadmap 2035+

October 16, 2026

A solid-state battery (SSB) is an advanced battery technology that replaces the liquid or gel-based electrolyte found in traditional lithium-ion batteries with a solid material. While standard lithium-ion batteries use liquid organic solvents to transport lithium ions between the anode (negative electrode) and cathode (positive electrode), solid-state batteries use solid electrolytes made of ceramics, glass, sulfides, or solid polymers. Fraunhofer ISI released its Solid‑State Battery Roadmap 2035+, gathering input from over 100 European experts to benchmark solid‑state battery (SSB) development against conventional liquid lithium‑ion batteries. Key takeaways from this perspective paper: ✅ Three major solid‑electrolyte families each have distinct trade‑offs ‑ Oxide (garnet): good chemical stability, yet high‑temperature sintering &

How to use historical data to reconnect the test? Neware BTS 8.0

October 15, 2026

How to use historical data to reconnect the test? The lab has experienced a power outage. After power was restored in the laboratory, the Neware BTS software prompted test channel protection. When double‑clicking the exclamation mark on the channel, a pop‑up window shows the message: “100396 If an abnormal power failure occurs, the connection cannot be directly connected. Check the hardware power supply circuit and data Integrity. If necessary, use historical data to connect”. Could you advise how to resolve this?
