LiPo Battery Dimensions: Why a Cell That Fits in CAD May Not Fit Your Product
A LiPo cell that fits in CAD may fail after PCM, wires and tolerances are added. Learn how to calculate and validate finished battery dimensions.
4.2V vs 4.35V 5000mAh LiPo Battery: Can the Same 1S Charger Be Used?
Need a 5000mAh LiPo battery replacement? Compare 4.2V vs 4.35V charging, PCM, fuel gauge, connector and OEM validation before choosing a replacement.
LiPo Battery Standby Drain: Why Smart Devices Lose Charge While Off
Diagnose LiPo battery standby drain in smart devices. Separate self-discharge, quiescent current and device sleep current, then set a storage-life budget.
Custom LiPo Battery Size Guide: How to Specify Pouch Cell Dimensions for OEM Products
Choose the right custom LiPo battery size for an OEM device. Learn how thickness, width, length, PCM, wires, connector, NTC and clearance affect finished pack fit.
LiPo Battery Voltage Sag: Why Devices Shut Down Under Peak Load
Diagnose LiPo voltage sag under peak load. Separate cell, PCM, harness and device-side losses, then release the pack from measured voltage margin.
Semi-Solid LiPo Battery: What OEM Engineers Should Validate
Compare semi-solid LiPo batteries by usable Wh, power, charge voltage, safety, swelling and lot consistency before approving an OEM pouch cell.
How to Diagnose LiPo Pouch Cell Swelling in OEM Products
Learn how OEM teams separate reversible pouch-cell breathing from residual swelling, control thickness and force measurements, and validate enclosure margins.
How to Read a Lithium Battery Datasheet: Why Higher mAh Can Deliver Less Runtime
Learn why a higher-mAh lithium cell may shut down earlier under load by comparing capacity, resistance, voltage sag, cutoff and usable energy.
Battery Pack Prototype Testing: From First Sample to Final-Device Validation
Learn how to test a custom battery pack from first sample through final-device and pilot-production validation, with clear acceptance and change control.
Battery Pack Thermal Management Guide: Heat Sources, Hotspots, Sensor Placement and Validation
