NREMPEROR 36V 2A Scooter Charger for EB5 EB7 EB8 — 10S (5.5×2.1mm or 5.5×2.5mm) with LED & Safety Protections

NREMPEROR 36 VDC 2A charger is a replacement power adapter designed to safely recharge 10-series (10S) 3.6–3.7V lithium battery packs used in EB5, EB7 and EB8 electric scooters and similar devices.

This compact charger accepts worldwide AC mains (100–240V, 50/60Hz) and delivers a regulated 2A output tailored for 10S lithium battery packs (nominal 36 VDC). It includes a two-color LED charge indicator, built-in safety protections and a 1 m cable to reach your device easily. The unit is intended as a direct replacement for original equipment chargers that match the same voltage and connector size—verify the connector diameter and battery chemistry before use.

Will this charger work with my EB5, EB7 or EB8 battery?

Yes, if your scooter or device uses a 10S lithium battery pack with a nominal 36 V (10 × 3.6/3.7 V cells) and the plug matches the charger’s connector, this adapter is compatible. It is not suitable for battery packs with different cell counts, voltages, or non-lithium chemistries.

• Output: 36 VDC (10S) at 2 A, suitable for 7.5–10.0 Ah range packs.
• Connector diameter options: 5.5×2.1 mm or 5.5×2.5 mm—confirm plug size.
• Not intended for 24 V systems or lower-voltage batteries.

How does the charger indicate charging status and end-of-charge?

Charging state is visible via a two-color LED: red while charging and green when the battery reaches full charge. The charger relies on the battery’s internal Battery Management System (BMS) to stop charging once the pack is full; if no BMS is present, manual monitoring is recommended.

• Red LED = charging in progress.
• Green LED = charge complete (BMS must allow automatic cutoff).
• Automatic detection requires a functioning battery BMS for safe termination.

What safety features and operating limits does the adapter include?

The charger integrates multiple protections to reduce risk during normal use: short-circuit protection, over-voltage and over-current safeguards, and reverse polarity identification. Keep the charger within the specified ambient ranges and avoid exposure to moisture or extreme heat for reliable operation.

• Protections: short-circuit, over-voltage, over-current, reverse polarity identification.
• Working temperature: -10°C to 50°C; storage up to 60°C; humidity up to 90% RH.
• Maximum recommended case operating temperature around 40°C; 100 cm cable length for flexibility.

How do I install and maintain the charger for best performance?

Connect the power cord to an appropriate AC outlet (100–240 VAC), then insert the DC plug firmly into the battery port. Avoid coiling the cable tightly while charging, keep vents unobstructed, and store the charger dry when not in use.

• Use the supplied power cord and confirm outlet voltage compatibility.
• Avoid charging in direct sunlight or near heat sources to protect lifespan.
• Inspect connector and cable for damage before each use; replace if worn.

Who is this for: This charger is aimed at owners of NREMPEROR-compatible EB series scooters and other devices that require a 10S (36 V) 3.6/3.7 V lithium battery charger with a 2 A charge rate. It’s a practical replacement for users who need a reliable, safety-minded adapter with LED status, universal AC input, and a standard barrel connector—ensure connector size and battery BMS compatibility before purchase.
