75104 Stellar CDTplus Battery 4-Pack - 3.2V LiFePO4 26650 - Hetronic Nova-XL - Fleet Pack

75104 Battery 4-Pack for Stellar CDTplus & Hetronic Crane Remotes

Keep your crew running. Fleet pack of 4 premium LiFePO4 batteries for Stellar CDTplus pistol grip remotes and Hetronic crane transmitters. Four high-capacity cells for $60 — that's $15 per battery, less than the price of 3 OEM singles. The CDTplus eats batteries if the crew leaves it on, and dead remotes mean a dead crane. Stock the truck with spares and never wait for a battery again. Free shipping.

The Problem

The Stellar CDTplus remote control is a battery vampire. Crews leave it on after the job, the battery goes flat overnight, and the next morning the crane won't respond. Now the service truck is sitting on a job site with a perfectly good crane and a dead remote. The foreman calls the office: "we need batteries."

You call the Stellar dealer. A single OEM battery is $22–$28. The industrial-labeled version from the transmitter manufacturer is $80+ per cell. And you need at least two — one for the remote and one spare. For a fleet of 5 trucks, you're spending $200+ per year just keeping remotes alive.

The Solution

We ship you a 4-pack of premium 3.2V LiFePO4 cells for $60 — that's $15 per battery. Put one in the remote and throw the other three in the glovebox. When the crew kills a battery (and they will), the spare is already on the truck. No downtime, no phone calls, no emergency orders.

⚠️ Critical: Why 3.2V LiFePO4 — Not Standard Li-Ion

This battery uses Lithium Iron Phosphate (LiFePO4) chemistry at 3.2 volts. This is not the same as a standard 3.7V lithium-ion cell. The voltage distinction matters:

• 3.2V LiFePO4: Matches the specific voltage curve of the Stellar/Hetronic charger. Charges correctly, operates at the right voltage, lasts the rated cycle life. ✅
• 3.7V Li-Ion: Wrong voltage. Will overcharge in the LiFePO4 charger, overheat, swell, and potentially damage the remote or charger. ❌

Do not substitute a standard 3.7V 26650 Li-Ion cell. It is the wrong chemistry. Our batteries are 3.2V LiFePO4 — the exact chemistry match for the Stellar and Hetronic charging systems.

Why LiFePO4 Is Better for This Application

• Safer chemistry: LiFePO4 cells are thermally stable. They do not overheat, swell, or catch fire under normal use — even if abused or short-circuited. Standard Li-Ion cells can thermal runaway. In a handheld remote that lives in a hot truck cab, safety matters.
• Flat voltage curve: LiFePO4 maintains a consistent 3.2V throughout most of its discharge cycle. The remote's signal strength and performance stay consistent from a full charge to near-empty — no gradual weakening.
• Long cycle life: LiFePO4 cells are rated for 2,000+ charge/discharge cycles, compared to 300–500 for standard Li-Ion. This means the battery lasts years, not months, even with daily charging.
• Cold weather performance: LiFePO4 handles cold weather better than standard Li-Ion. If your trucks work in freezing conditions, the remote battery won't quit when the temperature drops.

⚠️ Verify your remote takes a 26650 cell at 3.2V LiFePO4 before ordering. Open the battery compartment and check the existing cell — it should be a 26650 cylindrical cell (slightly larger than an 18650). If your remote uses a different cell size or chemistry, this is not the correct battery.

Why Buy the 4-Pack?

• $15 per cell vs $22–$28 OEM: You get 4 batteries for less than the price of 3 singles from the dealer. That fourth battery is essentially free.
• Always Have Spares: Put one in the remote, throw three in the glovebox or the tool cabinet. When a battery dies at 6 AM on a job site, the crew grabs a spare and keeps working. No emergency orders, no downtime, no angry foreman calling the office.
• Fleet Ready: Running 5 trucks with CDTplus remotes? Order 2–3 four-packs and distribute spares to every truck. At $60 per pack, it costs less than losing one hour of billable work to a dead remote.
• 3200mAh High Capacity: Virtually identical to the OEM 3300mAh rating. Full day of crane operation on a single charge.
• 2,000+ Cycle Life: Charge it every day for 5+ years before the cell degrades. These are not disposable batteries — they are long-term investments that pay for themselves in the first week.
• Free Shipping: $60 delivered. Done.

Battery Care Tips

• Charge overnight: Place the remote in the charger cradle at the end of each day. The LiFePO4 charger will automatically stop when the cell is full — no risk of overcharging.
• Don't store at zero charge: If a battery goes completely flat, charge it as soon as possible. Leaving a LiFePO4 cell at 0% for extended periods can cause permanent capacity loss.
• Keep spares charged: Store spare cells at approximately 50–80% charge. LiFePO4 cells have very low self-discharge — a charged spare will hold its charge for months in the glovebox.
• Avoid extreme heat: Don't leave the remote on the dashboard in direct sunlight during summer. High temperatures degrade all battery chemistries faster. The glovebox or a tool compartment is better.
• Turn off the remote: The #1 cause of dead batteries is crews leaving the CDTplus on after the job. Make it a habit — boom down, outriggers up, remote off. It takes 2 seconds and saves a battery.

Frequently Asked Questions

Can I use a regular 3.7V 26650 battery instead?
No. The Stellar and Hetronic chargers are designed for 3.2V LiFePO4 chemistry. A 3.7V Li-Ion cell has a different voltage curve and a higher charge voltage (4.2V vs 3.65V). The LiFePO4 charger will overcharge a Li-Ion cell, causing it to overheat, swell, and potentially damage the remote or the charger. Always use 3.2V LiFePO4 cells in these transmitters.

How long does a battery last on a full charge?
With 3200mAh capacity, a fully charged cell will run the CDTplus remote through a full day of normal crane operation (8–10 hours of intermittent use). Heavy, continuous use may drain it faster. If the crew is using the crane all day, having a charged spare on the truck eliminates any risk of downtime.

Are these the same size as the OEM battery?
Yes. Both the OEM and these replacements are 26650 cylindrical cells — 26mm diameter × 65mm length. They drop directly into the CDTplus battery compartment with no modification.

What's the difference between 3200mAh and the OEM 3300mAh?
100mAh — about 3% difference. In real-world use, this is indistinguishable. Both will run the remote for a full day. The 100mAh difference might mean 10 minutes less run time at the very end of a full discharge cycle — you would never notice it in practice.
