Frequently asked questions about the iTECH100SS 100Ah Lithium 12v Battery with Bluetooth

1. How long will a 100Ah lithium battery last (how many hours)?

A 100Ah lithium 12-volt battery can last an extended period, providing continuous power for various devices. Unlike AGM batteries, which typically have a lower usable capacity, lithium batteries utilise 100% of their power capacity.

This means you can rely on the full 100Ah to power your devices, ensuring longer runtimes and enhanced performance. As an example we ran a fridge which drew 1 amp per hour for just over 4 full days. 

2. How does the Bluetooth monitoring feature work?

The iTECH100SS has an internal battery monitoring system with Bluetooth, and is compatible with the iTechConnect Battery Management App. The iTechConnect app allows you to access real time key information on the current status of your battery including voltage, current capacity and temperature. For more information, download the Bluetooth App manual here. 

3. How much solar (number of solar panels) do you need to charge a 100Ah lithium 12v battery?

To charge a 100Ah lithium deep cycle battery effectively, we recommend a 2:1 ratio of solar panels to battery capacity. In this case, for every 100Ah battery, we suggest using approximately 200 watts of solar power.

Our range of solar panels, including 150-watt hard frame panels, 200-watt flexi panels, and 300-watt solar blankets, offers versatile options to meet your charging needs efficiently.

4. What size inverter do I need for a 100Ah lithium battery?

The battery itself can run up to 2000 Watts; however, the Anderson plug is only rated for 120 Amps 1536 Watts. We suggest the iTechworld 1000W Inverter
