Strengths and limitations

Strengths

  • 25.6 V, 100 Ah, 2,560 Wh (WattCycle).
  • 100 A continuous charge and discharge (WattCycle).
  • IP65; 7-year warranty (WattCycle).
  • Low-temperature charge protection (WattCycle).

Limitations

  • Cycle claims vary by WattCycle page, from 4,000 to 15,000. We show 5,000+ at 100% depth of discharge from the EU page.
  • Affiliate terms for WattCycle are not confirmed.

What it does not do

  • Work in a 12 V RV without a converter: it is a 24 V battery.
  • Scale past 2 in series and 4 in parallel (WattCycle).
  • Name a UL listing in the sources we read.

Power and travel notes

Rated capacity: 2560 Wh. Over 160 Wh: forbidden on passenger aircraft per FAA. Shipping by carrier follows separate DOT and carrier rules.

Real runtime is less than capacity divided by load: conversion losses, battery reserve and temperature all cut into it. Size a battery for your fridge.

Before you buy

  • Set your charger and controller to the battery maker's LiFePO4 voltages.
