The SOONEST 12V/24V deep-cycle LiFePO4 battery is available in 100Ah, 150Ah and 200Ah capacities for solar, RV, marine and backup power systems. Featuring 12.8V or 25.6V configurations and optional integrated BMS protection, it provides reliable and low-maintenance energy storage for mobile and off-grid applications.
The SOONEST 12V/24V Deep Cycle LiFePO4 Battery Series is designed for solar energy storage, recreational vehicles, marine systems, camping equipment, backup power and other applications requiring dependable deep-cycle performance.
Available in 12.8V and 25.6V nominal voltage options with 100Ah, 150Ah and 200Ah capacities, the series provides flexible energy-storage solutions for both small mobile power systems and larger off-grid installations.
LiFePO4 battery technology offers stable output, high usable capacity and low maintenance requirements, making it a practical alternative to conventional lead-acid batteries when used with compatible charging equipment.
Available configurations may include:
Final voltage and capacity combinations should be confirmed before ordering.
| Battery Configuration | Nominal Energy |
|---|---|
| 12.8V 100Ah | 1.28kWh |
| 12.8V 150Ah | 1.92kWh |
| 12.8V 200Ah | 2.56kWh |
| 25.6V 100Ah | 2.56kWh |
| 25.6V 150Ah | 3.84kWh |
| 25.6V 200Ah | 5.12kWh |
Nominal energy is calculated from battery voltage multiplied by rated capacity. Actual usable energy depends on the permitted depth of discharge, BMS settings, operating temperature and connected equipment.
The series is available in two nominal voltage platforms:
The battery voltage must match the inverter, solar charge controller, charger and connected DC equipment.
The battery uses lithium iron phosphate chemistry designed for repeated charging and discharging.
Main advantages include:
Actual performance depends on charging parameters, discharge current, temperature and application conditions.
Selected models can be equipped with an integrated Battery Management System to monitor battery operation and protect the cells from abnormal conditions.
Available BMS protection functions may include:
The exact BMS current rating and protection functions must be confirmed for each model.
The battery can be used as an upgrade option for many systems that previously used AGM, GEL or flooded lead-acid batteries.
Possible benefits include:
Before replacing a lead-acid battery, confirm that the existing charger, solar controller and inverter support the correct LiFePO4 charging profile.
The battery can store electricity generated by compatible solar panels for use at night or when solar production is insufficient.
It can be used with:
Charging voltage and current must remain within the battery specifications.
Selected models may support parallel connection to increase total storage capacity.
Some models may also support series connection to increase system voltage. Series and parallel capability depends on the battery and BMS design and must be confirmed before installation.
Only batteries with the same model, voltage, capacity, age and state of charge should be connected together.
The battery can provide stable DC power for compatible equipment such as:
Maximum continuous and peak discharge current must be matched to the connected load.
Unlike flooded lead-acid batteries, LiFePO4 batteries do not require routine electrolyte refilling.
Users should still inspect terminals, cables, connectors, enclosure condition and charging performance regularly.
The SOONEST deep-cycle LiFePO4 battery is suitable for:
The battery can provide stored energy for lighting, refrigerators, fans, televisions, water pumps, laptops, communication devices and other compatible RV or camping equipment.
Actual operating time depends on battery capacity, inverter efficiency and total connected load.
Selected models may be suitable for trolling motors, navigation equipment and onboard electrical systems when installed in a dry, ventilated and protected battery compartment.
Confirm the battery enclosure rating and marine installation requirements before use in wet or saltwater environments.
When paired with a compatible inverter, the battery can supply stored energy during utility power interruptions.
Possible backup loads include:
Backup time depends on battery energy, inverter efficiency and connected load.
Solar panels or another compatible charging source supply electricity through a charge controller or inverter charger.
The charger regulates the charging voltage and current according to the battery requirements. Once charged, the battery stores DC energy for later use.
When connected equipment requires power, the battery supplies DC electricity directly or through an inverter that converts DC power into AC electricity.
The integrated BMS monitors battery operation and disconnects charging or discharging when unsafe conditions are detected.
