Neware 5V20A 18650 Battery Charger discharger Capacity Testing System
1 . Accurate Timing
Most of us are considering the voltage and current accuracies are the all important factors of a battery tester , but actually timing accuracy is of the same importance .
Capacity or energy is calculated on time basis with the voltage and current measured , thus the timing accuracy will greatly affect the capacity calculated . To a general constant current or other constant testing regimes , this effect may not that easy to be observed .

2 . Data Security
Neware battery testing system utilizes LAN as the main framework to transfer data. This provides the most flexibility and reliablity to your system deployment.
When you look down into Neware batter, its unique Middle Machine architecture provides another enhancement layer to the data security issue. Moreover, this MM is an embedded system that allows you run tests even your LAN is down.
As we go deeper, dual embedded systems will have large redundancy to handle controls and data transfer.
