Lithium Battery Upgrade: Specifications and Charging Guide for OPLite

Lithium Battery Upgrade Specifications and Charging System

Summary: This article provides detailed specifications for the lithium battery upgrade and its charging system, including battery description, charging behavior, and relevant part numbers.

Battery Description

  • The lithium battery upgrade for the OPLite is designed to enhance the power capacity and efficiency of the camper's electrical system.
  • The charging voltage for the lithium battery is 14.4 V.

Charging Behavior

  • The OPLite lithium battery can be charged using solar panels that have an inbuilt solar controller. This controller monitors the battery status and prevents overcharging.
  • The unit features an SAE solar port, which is compatible with Zamp solar panels.
  • When connected via the 7-pin connector to a vehicle, the OPLite can receive a small charging current while driving. However, this does not provide the same charging performance as a dedicated DC-to-DC charger.
  • The charging current draw when plugged into a 120V outlet is approximately 15A, depending on the breaker.

Relevant Part Numbers

Lithium Battery Upgrade

You can replace your existing AGM batteries with 12V lithium batteries that fit within the available space in your OPLite.

With newer mini lithium options, you may even be able to increase your total amp-hour capacity while using a similar (or smaller) battery footprint.
