Why This Bundle
The EVE 30P pairs a strong 3000mAh capacity with a genuine 30A continuous discharge rating (under proper thermal management, 75°C cutoff) — a combination that puts real runtime and real current output in the same cell instead of forcing a trade-off. A cell this capable deserves a charger that treats it right. This bundle pairs 2 genuine EVE INR18650-30P Flat Top batteries with the NITECORE UI2 — a compact, USB-C powered charger that automatically selects the right charging mode and includes trickle charging and over-discharge protection. Everything you need to charge and maintain your cells, ready out of the box.

-
Independent Dual-Bay Control: each of the 2 bays charges independently without affecting the other
-
Trickle Charging: automatically switches to 100mA trickle mode for batteries below 2.9V, then up to 1000mA standard charging above 2.9V
-
Over-Discharge Activation: automatically detects and reactivates over-discharged protected Li-ion cells
-
Multiple Safety Protections: reverse-polarity/short-circuit protection, intelligent temperature control, and overcharge protection
-
Ultra-Compact & Lightweight: just 79.5g, 125.5 × 59.5 × 32.1mm
NITECORE UI2 – Supported Battery Types & Voltage
Charges 3.6V/3.7V Li-ion/IMR batteries, including the EVE 30P (18650) in this bundle:
10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14430, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 20700, 21700, 22500, 22650, 25500, 26500, 26650
Output voltage: 4.2V±1% Output current: up to 1000mA per bay (max 2 bays simultaneously)
Compatibility Notes
The UI2's charging bays are open-ended, allowing Flat Top batteries to seat securely without any adapter. EVE 30P Flat Top cells measure about 65.1mm, well within the UI2's compatible battery range.
Note: The UI2 charges at up to 1000mA per bay. High-drain cells like the 30P often support faster charge currents in a dedicated high-current charger, so expect a longer, gentler charge cycle on the UI2 — good for cell longevity, but budget extra time.
What's Included
- EVE INR18650-30P Flat Top Battery × 2
- NITECORE UI2 Charger × 1
- USB-C Charging Cable × 1
- User Manual × 1
Safety Tips
- Store batteries in a proper case, keeping them away from loose metal objects to prevent short circuits
- Never disassemble, puncture, burn, or submerge the batteries
- Charge only with a genuine, compatible charger such as the NITECORE UI2
- The 30P is an unprotected, high-drain cell intended for compatible, purpose-built devices — do not use it in unauthorized or modified equipment
- Never discharge below 2.5V or charge above 4.2V
FAQ
Q: Can the NITECORE UI2 charge EVE 30P Flat Top batteries safely? A: Yes. The UI2 automatically selects the optimal CC/CV charging mode for Li-ion cells like the 30P, with a 4.2V±1% output voltage and up to 1000mA per bay.
Q: Will Flat Top batteries sit properly in the UI2 charger bays? A: Yes. The UI2's open charging bays are designed to accommodate both Flat Top and Button Top cells without any adapter or modification.
Q: Can I charge both batteries at the same time? A: Yes. The UI2 has 2 independent bays, each capable of up to 1000mA, and one battery's charging status does not affect the other.
Q: Can I power the UI2 with a power bank while traveling? A: Yes. The UI2 has a USB-C input and works with any 5V power source, including power banks, solar panels, and USB wall adapters.
Q: What happens if a 30P battery has over-discharged? A: The UI2 includes an over-discharge activation feature that automatically detects and reactivates protected Li-ion cells that have dropped too low from storage or improper use. Note that the 30P is an unprotected cell, so always avoid discharging it below 2.5V in the first place.
Q: Is 30A continuous discharge safe for everyday devices? A: No — the 30P is a high-drain cell intended strictly for devices specifically engineered for high continuous discharge, such as power tools, e-bikes, and other high-drain battery packs. Always check your device's battery requirements before use.
Q: How does the 30P compare to the 20P? A: Both share the same 30A continuous discharge rating, but the 30P offers 1000mAh more capacity (3000mAh vs. 2000mAh), making it the better choice when you want both strong current output and longer runtime.
Q: What's in the box? A: 2 EVE INR18650-30P Flat Top batteries, 1 NITECORE UI2 charger, a USB-C charging cable, and a user manual.
