The new generation of lithium ion deep cycle batteries – suitable for 12v, 24v and 48v systems – gives you more power and a longer lifespan with zero maintenance and up to 70% less weight than standard batteries. This new generation of batteries is perfect for off-grid or on-board systems, as deep discharging will not shorten the battery’s lifespan like conventional batteries.
Lithium Batteries require a reliable BMS (battery management system) which must be used under any circumstance when using or storing batteries.
*Use of batteries without some type of BMS will void warranty, see CALB/Winston user manuals for more information.
