CT3603 is a multi battery monitor that can measure up to 18 batteries connected in series, with a total measurement error (TME) of less than 3.0 mV. The wide battery measurement range ranges from 0V to 5.5V, making the device suitable for most battery chemistries such as NCM, LFP, sodium ion, and lead-acid batteries. All 18 units can be measured within 329 µ s, and a lower data acquisition rate can be selected to achieve higher noise reduction effect.
