About this item 1% HIGH-PRECISION COULOMB COUNTING — Built on the 2nd-gen CZSOC
- ±1% HIGH
PRECISION COULOMB COUNTING — Built on the 2nd-gen CZSOC system with a 16-bit ADC, CZ212 measures real remaining capacity (SOC) by counting charge in/out, not by guessing from unstable voltage. Enjoy stable, linear, jump-free percentage readings — trust what you see, whether on a golf cart or in an RV. REAL-TIME SOC, VOLTAGE, CURRENT, POWER & TEMPERATURE — One glance shows remaining capacity (Ah + %), voltage, current (discharge shown as “-”), power (W/kW auto-switch), temperature (°C/°F), and auto-calculated remaining time in hours & minutes. Know exactly when to charge — no more sudden power loss mid-trip. PROGRAMMABLE HIGH/LOW VOLTAGE & 20% LOW-CAPACITY ALARMS — Set custom voltage thresholds (0.1-500V); when exceeded, the buzzer sounds and the reading flashes red. The low-capacity alarm triggers at 20% SOC. Together they help prevent over-charging and deep-discharging, protecting your battery investment. 300A SHUNT, WIDE SYSTEM COMPATIBILITY — Includes a 300A/75mV external shunt with acrylic base. Works with 12V-100V systems and Lithium, LiFePO4, Lead-Acid, Gel and AGM batteries — ideal for RVs, boats, golf carts, solar setups and forklifts. 1-TIME SETUP & LOW-POWER CONSUMPTION — Set your battery capacity once (long-press UP to sync 100% SOC on a full battery); no repeated calibration needed. 10-level brightness, auto screen-off (<100mA current), standby ≤1mA, and settings/data memory survive power-off.
