Kastar 3-Pack Battery and LTD2 USB Charger Replacement for Phase One

In this review of the Kastar 3-Pack Battery and LTD2 USB Charger replacement, the bottom line is simple: it is for photographers and imaging professionals who need reliable spare power and a flexible, portable charging solution for Phase One camera systems. The reviewer finds the three 2400mAh lithium-ion batteries useful for extended shoots and the dual USB charger valuable for fast, simultaneous charging, especially when traveling. The combination of Micro-USB and Type-C inputs, LED charge indicators, and a small 15W charger footprint make this kit a practical backup without complicated setup.

Key Features

• Triple battery pack: Three 2400mAh lithium-ion batteries provide substantial reserve power for long field sessions or multi-day shoots.
• Dual battery charger: The LTD2 charger can charge two batteries at once, reducing downtime between shoots and allowing one spare on standby.
• Flexible inputs: Micro-USB and Type-C inputs let users charge from common power banks or wall adapters when 5V 2-3A power is available.
• Intelligent LED display: LED indicators show charging status and remaining battery capacity so users can plan swaps with confidence.
• Interchangeable plates: The charger can change its plate to fit different battery shapes, increasing compatibility across Phase One models and similar packs.
• Portable and lightweight: With a 15W charger input and compact cables, the kit is easy to stow in camera bags for location work.

Who It's For

Photographers using Phase One IQ, IQ3, IQ4, P25, P30 and related medium format backs who need dependable spare batteries will appreciate this kit. It suits studio and location shooters who regularly swap batteries and want a compact charger that can top up two packs while a third is in use.

This is less suitable for users who demand OEM batteries or those requiring the absolute fastest proprietary charging protocols; the charger is a practical third-party solution rather than an OEM replacement for advanced battery management features.

Pros & Cons
