RELiON Battery released the newest lithium batteries in its Low Temperature battery lineup. The company announced the RB50-LT and RB300-LT, ideal to use in marine, RV and off-grid applications.
RELiON’s LT Series feature the same benefits over lead-acid batteries – including lighter weight, longer life and higher capacity – but, in addition, they also charge lithium batteries in freezing weather.
RELiON’s LT Series lithium batteries can be safely charged at temperatures down to minus- 4 degrees F. The system features proprietary technology, which draws power from the charger itself, requiring no additional components – making them safer and more practical to use in low temperatures.
“RELiON’s on a mission to power the world’s transition to lithium drop-in energy storage. Our engineers and product development teams originally developed the LT Series to solve common challenges with charging lithium batteries in freezing temperatures,” RELiON CEO Paul Hecimovich stated. “The success of the LT line has been phenomenal, and we’re excited to lead our customers’ call for new models in the lineup. At RELiON we look at the challenges our customers face and truly listen to their feedback. This enables our team to stay at the forefront of what our customers need. We strive for their experience with lithium to be easy so they can focus more on the journey ahead.”
Lithium batteries have limited charging capabilities in temperatures below 32 degrees. LT models contain a heating element that uniformly heats the cells within the battery to 32 degrees so that it can be charged at its full recommended current.
When a charge cycle is initiated in freezing temperatures, rather than the current going into the cells, the battery management system (BMS) diverts the current to the heating element. The heating element functions until the uniform internal battery temperature reaches 32 degrees, at which time it allows the current to charge the cells.
Uniform internal heating is an important LT model feature as many external heating blanket options currently available cannot sense the internal cells temperature and might not be completely effective at heating the battery throughout.
The new RB50-LT works in smaller applications such as remote monitoring, kayaking, camping and more. The RB300-LT provides a superior upgrade in recreational vehicles that spend time traveling in cold weather environments.
