The RB20-LT is a 12V 20Ah lithium battery and is part of RELiON’s Low Temperature Series. This lithium iron phosphate battery is specially designed for cold weather performance. RELiON’s LT Series batteries can safely charge at temperatures down to -20°C (-4°F) using a standard charger. The system features proprietary technology which draws power from the charger itself, requiring no additional components.
The entire process of heating and charging with the LT Series is completely seamless. Simply plug the battery in to the regular lithium charger and the internal heating and monitoring system takes care of the rest. Because it takes time to heat the cells, the charging process in below freezing temperatures could take a little longer.
The RB20-LT is ideal in a variety of applications including small solar energy systems, remote monitoring, LED lighting and traffic control cameras. It has all the benefits of lithium batteries including installation flexibility and no maintenance, with the added ability to charge in cold weather climates. It’s equipped with an M6 terminal type and a built-in battery management system (BMS).
RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer ultra-fast charging and discharging, high efficiency and a longer cycle life – plus no maintenance!
Not all lithium batteries are created equal. All RELiON Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.
