Choose your battery capacity based on daily energy consumption, time between charging opportunities, and your desired energy reserve.
The BUKNUWO 12.8V 100Ah battery provides 1,280Wh of nominal energy, while the 12.8V 150Ah battery provides 1,920Wh — 50% more stored energy.
A 100Ah battery can be a practical starting point for lighter daily loads with regular recharging. A 150Ah battery offers additional energy for higher consumption or longer stays between charges.

Not necessarily. Higher amp-hour capacity means more stored energy, but it does not automatically increase maximum output power.
Both the BUKNUWO 12.8V 100Ah Bluetooth and 150Ah Bluetooth batteries feature a 100A BMS for continuous discharge. Their nominal voltage and continuous-current ratings are therefore similar, even though the 150Ah model stores more energy. To run high-wattage appliances, check the battery's continuous discharge limit, inverter rating, appliance startup surge, cable sizing, and circuit protection.
Battery capacity primarily affects runtime; output capability determines whether a load can be supported.

Yes. A camper van's house battery can be charged while driving when the vehicle charging system is paired with a properly matched DC-DC charger.
The DC-DC charger manages charging from the vehicle electrical system and provides suitable charging voltage and current for the LiFePO₄ battery.
Before installation, confirm your vehicle's alternator capacity, DC-DC charger specifications, battery charging limits, and wiring requirements.
Do not assume that a direct alternator connection is suitable. Actual energy recovered depends on charger output, driving time, and battery conditions.

You may be able to reuse your existing equipment, but compatibility must be verified before installation.
For charging, confirm that your battery charger supports the voltage and charging profile required by the selected 12.8V LiFePO₄ battery. Some lead-acid chargers and smart chargers may not be suitable.
For an inverter, check the DC input voltage, continuous and surge power requirements, and the battery's discharge-current limits.
Also verify cable sizing, fuses, circuit protection, and the overall system configuration.
If you are unsure, contact BUKNUWO Support with your battery, charger, and inverter model numbers before connecting the equipment.

Installation may be possible if the compartment provides sufficient space and meets the battery's installation and environmental requirements.
Check the exact battery dimensions, terminal arrangement, mounting requirements, and available clearance for cables, inspection, and maintenance.
The installation location should be secure, dry, and protected from excessive heat, water exposure, and physical damage.
Do not assume that every 100Ah or 150Ah battery has the same dimensions. Always verify the specifications and permitted mounting orientation of the exact model before installation.

No. Low-temperature charging protection and self-heating are different features.
Low-temperature charging protection allows the BMS to restrict or stop charging when battery temperature falls outside the permitted charging range. This helps protect LiFePO₄ cells from unsuitable charging conditions.
Self-heating requires a separate heating system designed to warm the battery before charging.
Do not assume that a battery with low-temperature protection includes a heating function. Check the specifications of your selected BUKNUWO model before using it in cold weather.

No, different models cannot be connected in series or in parallel. Do not mix 100Ah and 150Ah batteries in the same series or parallel battery bank.
When expanding your battery capacity, use compatible batteries that have the same model, nominal voltage, and capacity, and are in similar condition and charge level, and follow the corresponding installation instructions.
Each battery is equipped with an independent Battery Management System (BMS), so differences in battery condition or electrical characteristics may affect charging and discharging behavior.
Before expanding your RV battery system, please contact BUKNUWO Technical Support to confirm supported series or parallel configurations, cable specifications, circuit protection measures, and charging equipment requirements.

Yes. A BUKNUWO LiFePO₄ house battery can be charged from solar panels through a compatible solar charge controller, such as an appropriately configured MPPT controller.
The controller must provide charging voltage and current suitable for the selected battery model.
Actual solar charging performance depends on panel output, sunlight availability, shading, controller efficiency, and battery conditions.
For off-grid van life, compare your estimated daily appliance consumption with the energy your solar system can realistically replenish. Solar panel wattage alone does not guarantee a full daily recharge.

Battery runtime depends on your actual energy consumption, not capacity alone.
A BUKNUWO 12.8V 100Ah battery stores 1,280Wh of nominal energy, while a 12.8V 150Ah battery stores 1,920Wh.
To estimate runtime, divide the energy available for your loads by their average power consumption. Account for inverter efficiency, operating hours, temperature, battery condition, and your desired energy reserve.
If your van uses multiple appliances, estimate their combined daily energy consumption rather than calculating each device in isolation.
Use the Van Life Power Planner above to compare your expected energy needs with both battery capacities.
