Kastar LCD Dual Fast Charger & 2X EN-EL18 Batteries - Reliable Dual

In this review of the Kastar LCD Dual Fast Charger & 2X Battery kit, the bottom line is simple: it is tailored for professional Nikon shooters and advanced enthusiasts who need reliable, high-capacity spares and simultaneous charging for long sessions. The kit pairs two 3200mAh lithium-ion replacements with a dual-slot LCD charger that intelligently identifies battery voltage and manages CC/CV charging to prevent overcharge. For anyone shooting events, wildlife, or long timelapse sessions, the biggest reason to buy is the ability to charge two batteries at once while monitoring charge status on an easy-to-read LCD.

Key Features

• Dual fast charging: The charger can charge two batteries at the same time, reducing downtime between shoots and letting you keep a fresh spare ready.
• Wide voltage compatibility: The charger accepts batteries between 6.8V and 16.8V and auto-identifies voltage so it works with multiple battery types and grips.
• Intelligent charging control: Built-in MCU manages CC/CV charging and prevents overcharge, helping protect battery longevity during repeated cycles.
• 3200mAh replacement batteries: Each included lithium-ion battery is 11.1V and 3200mAh, offering high capacity for extended shooting compared with lower-capacity cells.
• 0V activation and pre-charge: The charger can activate low-voltage li-ion cells and pre-charge them, which can be useful for reviving deeply discharged batteries safely.
• Complete kit: Package includes two batteries, an LCD dual charger, power cord, car adapter and a Europe plug, covering studio and travel charging needs.

Who It's For

The kit is best suited to photographers who use Nikon cameras and grips that accept EN-EL18-series batteries, including D4, D4S, D5, D800/D800E, D810/D810A and D500 with the MB-D12 or MB-D17 grips. Professionals shooting long events, sports, or location work will appreciate having two high-capacity spares and the ability to charge both simultaneously.

Beginners who rarely shoot full days or photographers who prefer original-brand batteries for warranty reasons may want to look elsewhere. Also note that for certain grips the kit mentions the need for an extra BL-5 battery cover, so users who rely on a grip should confirm accessory compatibility before purchasing.

Pros & Cons
