What Size DCDC Charger Do I Need With These Compact Lithium Batteries?

Our compact range of lithium auxiliary batteries are available in four sizes: 200Ah, 225Ah, 280Ah, and 310Ah, each designed to meet different levels of power demand for medium use 12V requirements in caravans.

For optimal performance and faster charging times, we recommend matching the charger size with your battery capacity:

  • 200Ah capacity: A 25A DCDC charger is ideal, providing a cost-effective option with an acceptable charging speed.
  • 225Ah and 280Ah sizes: A 40A DCDC charger is ideal, providing a good balance between charging speed and efficiency.
  • 310Ah capacity: Opt for a larger DCDC charger, such as a 50A model, to recharge more quickly and especially if you frequently use high-demand appliances.

All our Compact Lithium Batteries are engineered to work efficiently with DCDC chargers that can support the specific needs of lithium technology. Ensure that any DCDC charger you choose can accommodate the necessary settings for lithium batteries, typically requiring an absorption/float charge of 13.5 volts and a bulk charge setting of 14.2 volts.

If you’re considering a third-party charger or have an existing charger, verify that it is compatible with lithium batteries and meets these voltage requirements to ensure safe and efficient charging.

Can I Directly Swap My AGM Battery with a Lithium Battery?

Switching from an AGM to a lithium battery in your caravan involves more than just swapping the units due to different charging requirements and battery chemistries. Lithium batteries, while lighter and more efficient with a longer lifespan, need precise charging to avoid overcharging and potential safety risks.

Before making the switch, verify that your existing charging equipment, including DC-DC chargers, solar charge controllers and 240V chargers, are compatible with lithium technology. Check your equipment manuals thoroughly to ensure they can accommodate lithium batteries, ensuring a safe and effective upgrade.
