Lithium- Ion batteries revolutionized DPV world, allowing to condense electric power source in much smaller and lighter size compared to old Ni-Mh, and lead-acid technologies.
Due to extreme power, it requires well designed and executed construction. Seacraft manufactures batteries in own facility using a highest quality single cells, and modern technology. Single battery packs are welded with thick steel plates what provides great mechanical strength, and reliable work even with high load for extended time.
