LEARN MORE - about the easy to install Daly BMS Smart App:

BLUETOOTH PHONE INTERFACE for displaying battery information on your phone! Giant Power 12V Lithium batteries can also be connected two in parallel to double the Amphours or two in series to make 24V. The built-in 100AMP DALY Battery Management System is easily accessible via a phone APP. In the app you will be able to monitor and check the battery’s current state of charge, current voltage, current cycles status and temperatures, individual cell voltages and the minimum and maximum voltages. The BMS provides 2 temperature sensors (1 for prismatic cells and 1 for the BMS itself) protecting against over-charging, over-discharge and short-circuiting and also amplifies the battery lifespan. The no memory effect means this battery can be charged and used at any time in any condition, so no need to discharge the battery before charging.

With Giant Power Lithium Batteries you don’t need a special battery charger! GIANT batteries are manufactured with a built-in high-quality battery management system (BMS) that allows for most charger settings (20A)min (except flooded) to be used. This means you can use your current AGM charger as long as it’s 20A minimum.

We recommend the Ardent Lithium 20A Battery Charger. Designed for larger batteries anywhere from 100AH to 200Ah, these portable car chargers automatically adjust to suit the battery type in any caravan, car or boat application and tailor a charging solution to suit its needs.

Very happy with the quality of this Kit and Great

We used this for weeks camping on Fraser Island and simply remove your battery box from your vehicle if you don’t need it taking up space, or if you want it to reach other appliances at your campsite. Everything worked well and we charged with a solar panel which plugged straight into the battery box.
