Solar-Ready 12V 200Ah Deep Cycle LiFePO4 Caravan Battery Pack with Bluetooth BMS Off-Grid Living

The ECER DCB-12200 is a solar-ready 12V 200Ah deep cycle LiFePO4 caravan battery pack engineered for serious off-grid enthusiasts who refuse to compromise on comfort during extended wilderness stays. With a substantial 2560 watt-hours of usable energy storage and a robust 200-amp continuous discharge capability, this battery pack effortlessly powers energy-intensive caravan appliances including inverter-driven air conditioners, induction cooktops, electric water heaters, and large compressor refrigerators without voltage sag or premature low-voltage disconnect. The built-in Bluetooth BMS brings a new level of user engagement to battery management, providing real-time visibility of state of charge, current flow, individual cell voltages, cycle count, and temperature directly on a smartphone app for both iOS and Android platforms. Designed from the ground up for solar integration, the DCB-12200 pairs perfectly with rooftop arrays ranging from 400W to 1200W, storing surplus daytime generation for evening use and enabling truly autonomous off-grid living without the noise, maintenance, and fuel logistics of portable generators. The heavy-duty ABS enclosure with integrated carrying handles and M8 brass terminals accommodates both permanent installation and portable power station configurations, making this battery equally at home in a fixed caravan electrical system or a removable power pack for campsite use.

• Solar-Ready Architecture: Engineered specifically for photovoltaic charging with an optimized charge acceptance curve that maximizes solar harvest from dawn to dusk. Compatible with all MPPT and PWM solar charge controllers up to 60A input, and supports simultaneous charging from solar and vehicle alternator via a DC-DC charger for rapid replenishment during driving segments between campsites.
• Bluetooth BMS with Smartphone App: The integrated Bluetooth 5.0 BMS streams real-time battery data to the ECER Battery Monitor app available on iOS and Android. Users can view state of charge percentage, instantaneous charge and discharge current, individual cell voltages, internal temperature, cycle count, and protection event history. Configurable alerts notify users of low state of charge, high temperature, or over-current events before protection thresholds are reached.
• 200A Continuous Discharge Capability: With a robust 200A continuous and 400A peak discharge rating, the DCB-12200 comfortably supports 2000W to 2400W inverters for running high-power AC appliances. The low internal resistance of LiFePO4 cells maintains stable voltage output even under heavy inverter loads, eliminating the inverter shutdown issues common with lead-acid batteries experiencing voltage droop under surge currents.
• 6000+ Deep Cycles for Full-Time Living: For full-time caravan dwellers cycling the battery daily, the 6000-plus cycle endurance at 80 percent depth of discharge translates to over 16 years of reliable service. This dramatically reduces the total cost of ownership compared to AGM batteries requiring replacement every 18 to 24 months under similar cycling conditions, making the DCB-12200 a compelling investment for long-term off-grid lifestyles.
• 2560Wh Massive Energy Reserve: The 200Ah capacity at 12.8V nominal delivers enough energy to run a 12V compressor refrigerator for 4 to 5 days, LED lighting for 40-plus hours, a diesel heater for 3 nights, and multiple device charging sessions on a single charge. For mixed AC and DC loads, this capacity provides 2 to 3 days of autonomous operation for a typical 2-person caravan without solar input, and indefinite operation when paired with adequate solar generation.
• Parallel-Ready for Unlimited Expansion: Connect up to 4 DCB-12200 units in parallel for an 800Ah 12V bank delivering 10.24kWh, sufficient for all-electric caravan setups with induction cooking, electric hot water, and air conditioning. The Bluetooth BMS on each unit operates independently while the parallel connection balances current sharing automatically, and the smartphone app can display aggregated data from all connected batteries when within Bluetooth range.
• Ruggedized Construction for Mobile Environments: The 2mm thick ABS case with internal aluminum chassis reinforcement withstands the constant vibration and mechanical shock of unsealed road travel. Silicone-gasketed case seams and terminal boots provide IP65 protection against dust and water spray, while the brass M8 terminals with nickel plating resist corrosion in humid coastal environments. Integrated fold-down carrying handles support the 23.5kg weight for portable applications without requiring separate straps or cases.

The DCB-12200 is purpose-built for the growing community of full-time caravan dwellers and extended off-grid travelers who demand household-equivalent electrical capability without generator dependency. In a well-equipped 7-meter caravan with 800W rooftop solar, a single DCB-12200 supports a 12V compressor refrigerator running continuously, LED lighting throughout, water pressure pump for daily showers, diesel heater for cold-weather comfort, laptop and device charging for remote work, and a 2000W inverter powering a microwave, coffee machine, and occasional induction cooking, with state of charge typically remaining above 50 percent by sunset during summer conditions. Two units in parallel at 400Ah enable all-electric operation including air conditioning for afternoon siestas, electric hot water system, and entertainment systems for family movie nights, achieving true energy independence without propane or generator backup. For professional applications, the DCB-12200 serves as a reliable power source for mobile medical clinics, field research stations, event catering trailers, and broadcast van auxiliary power, where silent operation and zero exhaust emissions are critical requirements in noise-sensitive or enclosed environments. The Bluetooth monitoring capability is particularly valuable for rental caravan fleet operators who can verify battery health and charge status during vehicle turnaround without opening battery compartments or using specialized test equipment. For marine applications, the IP65 enclosure and corrosion-resistant terminals make the DCB-12200 suitable for house bank duty on sailing yachts and motor cruisers operating in saltwater environments, though professional installation with appropriate fusing and isolation is recommended for marine electrical systems subject to ABYC or equivalent standards.

Each DCB-12200 is individually packaged in a double-wall corrugated carton with CNC-cut EPE foam inserts that immobilize the battery during transit while allowing the integrated carrying handles to remain accessible for easy unpacking. The main terminals are covered with protective plastic caps and the battery is shipped at approximately 30 percent state of charge to comply with UN38.3 transportation safety regulations for lithium batteries. Two units are consolidated per master carton on standard 1200 x 1000mm pallets with edge boards and stretch wrapping for LCL and FCL shipments. Every battery is accompanied by a factory test report documenting: open circuit voltage and internal resistance of each cell, total capacity verified at 0.2C discharge rate, BMS protection threshold testing for over-voltage, under-voltage, over-current, and short circuit events, and Bluetooth communication range and data accuracy verification. ECER provides a 5-year limited warranty covering manufacturing defects and capacity retention above 70 percent within the warranty term. Post-sales support includes the ECER Battery Monitor app with over-the-air firmware update capability, installation guidance documentation, and direct engineering support for system integrators developing custom battery management and display solutions. Volume OEM orders of 200 units or more can specify custom enclosure colors, private label branding, terminal configuration, and Bluetooth app white-labeling for a fully branded customer experience.
