72V Power for Your Advanced EV Advent HD
The Advent HD is Advanced EV's heavy-duty platform — built for hauling, towing, and demanding terrain. This 76.8V LiFePO4 conversion kit delivers the sustained power and extended range your HD was designed for, without the weight and maintenance of lead-acid.

Controller Compatibility
The Advent HD uses a 72V AC motor controller. The 76.8V Fleet Lithium pack is a direct replacement for the factory lead-acid bank. No controller reprogramming required for standard installations.
What's Included
- 76.8V NexGen Fleet Lithium LiFePO4 Battery (selected capacity)
- CH8713 — 87.6V 13A LiFePO4 Smart Charger
- BR6201 — Advanced EV Advent HD Bracket Kit
- AC0219 — AC Power Connector with Cover Plate
- CB0917 — 1/0 AWG Cable Set (35.4")
- Digital State-of-Charge Gauge
- All mounting hardware
Key Specs
- 300A NexGen BMS with 800A peak surge
- Patent-pending fire suppression system
- Built-in cold-weather heater — activates automatically below 32°F when charging
- Bluetooth 5.0 monitoring — voltage, temp, cycle count from your phone
- 10-year warranty — designed and assembled in the USA
Why the HD needs lithium
- Sustained power under load — lead-acid voltage sags when towing; lithium holds steady
- 70% weight reduction — less dead weight means more payload capacity for your HD
- Faster recovery — full recharge in 4–6 hours vs. 8–12 for lead-acid
- 10-year lifespan — outlasts 3–4 sets of lead-acid batteries
Is the Advent HD different from the regular Advent?
Yes. The Advent HD runs a 72V system (vs. 48V on standard models) and uses a different battery tray. This kit uses the BR6201 bracket designed specifically for the HD chassis. Do not use a 48V kit on a 72V Advent HD.
Do I need to reprogram my controller?
No. The factory 72V AC controller is compatible with the 76.8V lithium pack out of the box.
How long does installation take?
30–60 minutes with basic hand tools.
Does it work in cold weather?
Yes. The integrated heater activates automatically below 32°F when plugged in for charging — standard on every pack.
*Range estimates are maximums under ideal conditions (flat terrain, single rider, 12–15 mph, 70°F). Actual range varies with terrain, weight, speed, and temperature.
