Quick Guide to Lithium Leisure Battery Care for Campervans

This guide covers everything you need to know about storing, charging, and isolating your lithium batteries.

Storing Lithium Batteries

  1. Charge to 50%-60% SOC: Store batteries at around 50% to 60% state of charge to minimize stress and prolong lifespan.
  2. Cool, Dry Place: Keep batteries in a cool, dry location, ideally between 10°C and 25°C.
  3. Periodic Checks: Check the battery’s charge level every few months and recharge to 50%-60% if needed.

Charging Your Lithium Batteries

  1. Use a Suitable Charger: Ensure your charger is compatible with lithium batteries to regulate voltage and current.
  2. Avoid Overcharging: Prevent overcharging by using chargers with overcharge protection and a suitable charge rate, about 30% of your batteries capacity is a good rule of thumb.
  3. Balance Charging: Occasionally perform a balance charge using a BMS-equipped charger to ensure all cells are equally charged.

PV Isolation (Solar Panels)

  1. Install a Charge Controller: Use a charge controller between your solar panels and the battery to regulate voltage and current.
  2. Monitor Charge Levels: Regularly monitor your system with apps or interfaces to track real-time charge levels.
  3. Disconnect When Not in Use: Disconnect solar panels during extended periods of inactivity to prevent unwanted battery drain or overcharging.

General Tips for Battery Care

  • Avoid Deep Discharges: Try not to let your battery drop below 20% SOC frequently, as deep discharges can reduce its lifespan.
  • Inspect Regularly: Check your battery and connections regularly for signs of wear or damage.
  • Clean Connections: Ensure battery terminals and connections are clean and free from corrosion.

By following these storage, charging, and PV isolation tips, you can ensure your lithium leisure batteries provide reliable power for all your campervan adventures. For more detailed advice and battery options, feel free to contact our team or visit our online shop.
