Do you mean 56v with 24" hedge trimmer since Ego doesn't make a 54V 26" one. If so, it comes with one. Or, are you saying you need to replace the one it came with? If so, call 1-855-EGO-5656 (1-855-346-5656) from 8:30AM - 8:00PM EST (Monday - Friday) & 10:00AM - 6:00PM EST (Saturday & Sunday). Be sure to call early in the day to avoid long hold times.
