Kastar BP-950G Pro 4-Pack Battery and LTD2 USB Charger - High-Capacity

In this review of the Kastar BP-950G Pro 4-Pack and LTD2 USB dual charger, the bottom line is simple: this kit is for camera operators who need reliable, portable power for long shoots and compatible Canon and RED Komodo models. The reviewer found the four 5800mAh batteries and the Micro-USB/Type-C equipped charger deliver convenient, high-capacity runtime and flexible charging options, making it a practical replacement set for workflows that value on-the-go recharging from 5V USB sources.

Key Features

• High capacity: Each 5800mAh lithium-ion battery provides extended run time for long recording sessions and reduces the need to swap batteries frequently.
• USB charging: The charger accepts Micro-USB and Type-C input so batteries can be charged from 5V 2-3A wall adapters or portable power banks for field convenience.
• Dual battery charging: The LTD2 charger can charge two batteries simultaneously which speeds turnaround between takes.
• LED status display: Four LED lights on each battery and the intelligent LED charger display make it easy to monitor charge progress and remaining capacity.
• Wide compatibility: Works with a long list of Canon BP-series battery models and fits cameras including Canon XF and some cinema models and the RED Komodo 6K, making these batteries versatile spares.

Who It's For

This kit suits independent videographers, ENG shooters, and event photographers who operate Canon XF205, XF300, XF305, XH and XL series cameras or the RED Komodo and need multiple high-capacity spares. The USB charging options benefit those who travel or shoot on location and rely on common 5V power sources rather than proprietary chargers.

It is less appropriate for studios that already use dedicated high-power charging racks or for users who require OEM batteries exclusively; those buyers should consider manufacturer-supplied batteries and chargers that match studio workflows and warranties.
