Do the black and red leads connect to 12 volts source voltage?** A: I think there are 2 ways to wire. 1, from a power source 2, from the induced power from hall tranformer. Look at Web sitell it shows schmatic. **Q: Does this version Have ability to reset ah and kwh?** A: This battery tester/gauge is just a display device. If you remove the monitored voltage/current the meter automatically resets it self. Actually it just turns off and when you reapply the voltage/current it will show the new data for the system you are monitoring. Hope this helps! **Q: will I need two being I’m using a battery isolator for my two batteries for my audio system?** A: If you are isolating each battery from the other then the I think that the answer is yes. You would need 2 to be able to read each battery independently. ## Frequently Bought Together - AiLi Battery Monitor DC 300V 100A Voltmeter Ammeter Voltage Amp Meter Gauge with Hall Effect Sensor Transformer - Klein Tools MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity - Mighty Max Battery ML5-12 - 12 Volt 5 AH Rechargeable SLA Battery - Mighty Max Brand Product --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/84308868-battery-monitor-dc-300v-100a-voltmeter-ammeter-voltage-amp-meter](https://www.desertcart.vu/products/84308868-battery-monitor-dc-300v-100a-voltmeter-ammeter-voltage-amp-meter) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
