Detailed Description
Product Overview

The 24V 300Ah LiFePO₄ battery is the energy core designed for high‑consumption RVs, converted buses and off‑grid homes. With 7.2kWh of total energy, it can power a 2000W induction cooktop for 1 hour, a 1200W RV air conditioner for 5‑6 hours, plus auxiliary devices like fridge, lights and water pump all day long. Using Grade A LiFePO₄ cells and an active balancing BMS, each cell string is kept in optimal condition, greatly extending cycle life and safety margins.

Why 24V systems are favored by premium RVs?
  • Balance of performance and cost – 24V cuts current in half compared to 12V, reducing cable losses and thickness; inverters and chargers are widely available at lower prices than 48V systems
  • Good compatibility – Many imported RVs come with a native 24V platform, so upgrading to lithium does not require replacing the entire electrical architecture
  • Safety – Still falls within safety extra‑low voltage range while supporting larger loads (3000W‑5000W inverters)
  • Flexible expansion – Paralleling 6 units yields 43.2kWh, enough for a fully self‑sufficient RV or even a small off‑grid home
Advantages of active balancing BMS
  • Unlike passive balancing (resistor bleeding), active balancing transfers energy from high‑voltage cells to low‑voltage cells with over 90% efficiency
  • Significantly reduces capacity loss caused by cell inconsistency, making overall battery life close to the cell limit
  • Especially suitable for large‑capacity multi‑parallel systems – voltage difference can be kept within 10mV after long‑term operation

FAQ

Q: Can it directly replace the original lead-acid battery?

A: Yes, 12.8V is compatible with 12V systems, with adaptive size and consistent positive and negative poles, plug and play; it is recommended to check if the charger supports LiFePO4 (14.4V-14.6V).

Q: Does it support parallel expansion with multiple batteries?

A: Yes, it can be paralleled with up to 4 batteries, with a total capacity of 1600Ah, meeting the demand for large loads.

Q: Can it be used in low temperatures in winter?

A: The standard version can be charged above 0℃; the optional low-temperature heating version can be normally charged and discharged at -20℃, suitable for RVs in northern winter.

Q: How long is the service life and warranty period?

A: 3000+ cycles (70% DOD), usable for 8-10 years under normal use; 5-year warranty (free of charge for non-human damage).

Q: Is maintenance required?

A: Zero maintenance, no need for water replenishment, balancing or regular charging, low self-discharge rate, and slow power loss during long-term storage.

Q: Is it safe? Will it explode?

A: It adopts LiFePO4 (lithium iron phosphate), which has stable chemical properties, non-flammable and non-explosive; built-in BMS multiple protection and flame-retardant shell, safe and reliable for RV use.
