Installation

Wiring Diagrams & System Architecture

Wiring batteries in series or parallel safely starts with the right documentation for your exact model.

  • Series & Parallel Limits by Model

    How many batteries you can wire in series (24V/36V/48V banks) or parallel depends on the model and its BMS. Always confirm the limits on your battery’s datasheet first.

    Check your datasheet

  • Step-by-Step Wiring Instructions

    Every user manual includes the wiring and installation steps for that model, including safe series and parallel bank configurations.

  • 48V-to-12V Voltage Reducers

    Running 12V lights or accessories from a 48V system? Use a dedicated voltage reducer instead of tapping a single battery.

Do I need a special charger for my Epoch LiFePO4 battery?

Yes, to ensure a 100% full charge and to get the longest service life from your battery, you should use a charger equipped with a dedicated Lithium (LiFePO4) charge profile. You can view our recommended charging voltages in the specific User Manual for your battery above.

Full answer on the FAQ page
Can I wire my Epoch batteries in Series or Parallel?

This depends entirely on the specific model and BMS of the battery you purchased. Some models allow up to 4 in series and 4 in parallel, while massive high-capacity and 48V models are strictly for parallel use only. Please check the Wiring Diagrams section above or refer to your specific battery's datasheet before wiring your system.

Full answer on the FAQ page
How do I register my battery for the 11-Year Limited Warranty?

Register your product within 90 days of purchase on our Warranty Registration page, with your order number, purchase date and the battery's serial number. Registering confirms your coverage start date quickly; if you keep your proof of purchase, your warranty does not depend on registering.
