Tomberlin E-Merge Shadowhawk 48V Lithium Battery Conversion Kit
Fleet Lithium for your Tomberlin E-Merge Shadowhawk
Upgrade your lead-acid Shadowhawk with a matched Fleet Lithium system. Choose the capacity for your passenger load, hills and daily driving, with a lithium charger and digital charge display.
Model years and battery compatibility
Shadowhawk models can have lead-acid or factory EVOLVE lithium systems. Identify the actual battery chemistry, tray and controller rather than assuming compatibility from a 2024–2026 model-year label.
Confirm fitment before ordering: match the complete 48V lead-acid bank, tray, selected capacity, controller, charger and finished mounting kit. Factory EVOLVE lithium, 72V vehicles and unverified modified drivetrains are outside this conversion procedure.
Choose your Tomberlin lithium battery capacity
All options are 51.2V nominal LiFePO4 systems for compatible 48V vehicles.
| Capacity | Battery arrangement | Nominal energy | Best suited to |
|---|---|---|---|
| 65Ah | One pack | 3.33 kWh | Confirmed stock vehicles with modest energy needs |
| 105Ah | One pack | 5.38 kWh | Everyday driving with regular charging |
| 168Ah | One pack | 8.60 kWh | More reserve in a single battery |
| 210Ah | Two matched 105Ah packs in parallel | 10.75 kWh | The largest energy reserve in this bundle range |
The 168Ah option stores 60% more nominal energy than 105Ah; 210Ah stores twice as much. Actual driving range varies with load, terrain, tires, speed, temperature and accessories. Capacity is not a speed upgrade. Modified motors and controllers need a specific compatibility check.
Your matched conversion system
The bundle pairs the selected 51.2V nominal LiFePO4 battery configuration with a lithium charger, SOC display, mounting hardware and wiring for the confirmed vehicle configuration. Confirm the exact finished bracket and kit contents with Fleet; the model name alone does not identify every tray or electrical interface.
For 210Ah, use two matched 105Ah packs with the approved parallel harness, individual branch protection and restraint. The 65Ah option is for confirmed stock motor/controller configurations.
Less battery upkeep, continued support
Eliminate electrolyte top-ups and lead-acid equalization charging. Monitor charge and battery status with the supplied display and Bluetooth-enabled NexGen BMS. Continue normal cable, mounting and charging checks. The battery is covered by Fleet’s published 10-year golf cart/EV battery warranty.
Installation resources and common questions
Which model years are compatible?
Shadowhawk models can have lead-acid or factory EVOLVE lithium systems. Identify the actual battery chemistry, tray and controller rather than assuming compatibility from a 2024–2026 model-year label. Year alone is not a mounting or electrical fitment guarantee.
Can I keep the original charger?
Use the matched Fleet lithium charger and charge display supplied for the conversion. Do not charge the new system with the old lead-acid charger.
Does the vehicle retain the charger drive-away interlock?
No. The current Fleet Tomberlin kit eliminates the original charger interlock. The vehicle may move while plugged in. Keep the key OFF while charging; disconnect and stow the AC cord before key ON.
Where can I see an installation and compare options?

Let customers speak for us
What a fantastic upgrade from my old acid batteries. It was time and I’m so impressed. Shipping came smoothly. Customer service has been fantastic and looking forward to the adventures to come including camping, RV, fishing, boating.
The customer service and the battery itself from Fleet Lithium is unbeatable. One of the best experiences as a customer I have ever had. They stand by their product and help you every step of the way to ensure you are happy in your purchase. The install was easy once you know where everything is supposed to go and the battery has performed flawlessly in my Bad Boy Recoil since installation. It made it a lot lighter and the buggy is obviously quicker now and I was able to ride it around the farm for hours in fast mode the other day and only used 25% of the battery carrying a buddy and myself. It is really amazing.
Cannot thank these guys enough. Our Hunting buggy is a whole new animal of its own! The team did a great job answering questions, shipping took 3 days and i was even able to reach the support team at 4pm on a Saturday during install. Cannot thank them enough! Don't think twice, Fleet is the way to go for your lithium job.
Was a slight hick up with the darn computer bot. Once we got thru that the service and help with my change over was top notch.
Mt Ranger performance is awesome with the Fleet battery
GREAT SERVICE
Awesome kit. We Live in a very cold climate, our ranger gets a ton of use year round and especially during the winter so the cold weather performance was a must for us. We've had the kit installed for about a year now and it's been perfect. Customer service has been super helpful the one or two times we had questions and we've got a couple of neighbors who run the kits as well and they say the same thing. Kevin and his crew are really top notch!
The 12V voltage reducer corrected the unstable behavior that had affected the lights and other accessories. The output has remained steady through regular use.
The 51V replacement charger is easy to keep available as a backup and works without unnecessary controls. The battery reaches a complete charge consistently during normal use.
The Polaris Ranger EV bundle lined up well with the intended mounting area and the connections were easy to identify. Once installed, the vehicle felt smoother and more consistent through normal use.
The 51V replacement charger connected as expected and has charged the compatible battery consistently. The status indicators are easy to follow, and the unit feels solid in regular use.
Easy installation and great technical support.
After installing the Club Car 48V kit, throttle response felt more immediate and the vehicle no longer felt sluggish late in the charge. The cleaner battery compartment is another welcome improvement.
Cabels look great. Will be installing them by the end of the week. Frank
The BlueMax 200Ah marine battery has provided steady power for onboard electronics and normal time on the water. It is easier to handle than the older battery and has required very little attention between trips.
The parts for the EZGO TXT kit were organized clearly and the installation sequence made sense. The finished setup looks tidy and removes the routine upkeep of the old battery bank.
