Upgrade Your E-Z-GO TXT 2+2 to Fleet Lithium
The TXT 2+2 carries four people on the same six 8V lead pack the two-seater uses, which is why it feels tired on hills and short on range by the end of the day. One 51V Fleet Lithium pack removes about 230 lb, holds full voltage with a full load, and turns an overnight charge into a couple of hours.
