Responses Faster.
Switches More Smoothly.

Neware BTS 4000 features with a response time of 10ms. And this value can be down to less than 1ms if the current range is lower than or equal to 12A (typical models will be 5V12A, 5V6A, 5V10mA, 5V20mA, 5V50mA).

And the swiching process(from rest to charge, charge to discharge, rest to discharge, or the other way) is much better than what most of our competitors provide.

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.
