CES (Central Energy Source)

Featured Product:


The Central Energy Source (CES) is the latest in a family of Conformable batteries from Denchi Power. The evolutionary device replaces the normal rigid case with a flexible canvas covered pouch. The pack can store, deliver, and scavenge power lessening the weight burden and eliminating cables and the need to carry spare batteries. This battery incorporates its own integrated charging circuitry and offers flexibility and seamless plug and play. It will power a broad range of electronic devices and can scavenge power quickly from equipment such as solar panels, vehicles or other primary or re-chargeable batteries.
