Deep Cycle Systems 120Ah Slimline Deep Cycle LFP Battery Deep Cycle Systems

ALL NEW CYLINDRICAL CELL PACK TECHNOLOGY FOR 2024.

• Cell Pack and BMS is completely sealed inside a Thermal Interface Resin.
• Thermal Interface Resin technology provides dramatic improvements in thermal management, vibration resistance, durability and cycle life.
• Increased passive cooling performance through an all Aluminum construction. 
• Laser-welded Cell Pack construction for superior mechanical strength.
• New, refined LFP Chemistry with improved energy density. 

THE BMS

DCS LFP Batteries are engineered to perform in the most harsh operating conditions.

Every DCS LFP battery features DCS own custom and proprietary BMS that has been continuously refined and improved up since it was first introduced in 2018. The DCS 3S BMS is paired with our stand-alone DCS 16 channel 59.2A Active Cell Balancing System. Both have been designed to pass MIL-STD-810G (Method 514.6) vibration testing requirements which ensures that these batteries remain reliable even in the most punishing of conditions.

THE APP

All DCS LFP batteries also feature our comprehensive Bluetooth system that in conjunction with the DCS LFP App displays the following:

• Battery pack Voltage.
• State of Charge (SOC) % estimate via impedance tracking.
• Amp meter displaying real time charge and discharge current.
• Time remaining (estimate in real time).
• BMS Mosfet temperature status (for winching or large inverter loads).
• Battery pack cycle count.
• Cell status showing real-time active balancing operation.
• More accurate data compared to external battery monitors (shunts).

THE BATTERY

The 120Ah Slimline battery features two pairs of Anderson connector terminals (one positive and one negative) that are internally bridged with copper busbars and included are two pairs of 120A Anderson connectors with cables & lugs which provides more surface area for additional connections, enables a cleaner and more organized cable management when parallel connecting multiple batteries. Also included is a set of four wall mounting brackets.

The metal enclosure ensures that the battery is fully serviceable, even after the 5 year warranty period has expired, so that the battery can be serviced and components replaced. The unique form factor of these Slimline batteries make them ideal for installations locations that are space challenged.

THE CYCLE PERFORMANCE

This Battery is rated to achieve a minimum of 4000 cycles @ 100% DOD (when ≤ 80% of its original capacity retention has been reached @ 77F). That means that this battery is rated to achieve at least 4000 cycles by the time it has faded 20% from its original capacity, that is, when ≤ 80% of its original capacity retention has been reached.
