6.0V 2650mAh 4-Pack Ni-MH Batteries with Smart USB Charger - Compact

In this review the reviewer tested the Kastar 4-pack battery kit designed for camcorders and thermal/IR units; the bottom line is that it is a practical, travel-friendly replacement power solution for users who need reliable Ni-MH cells and a simple USB charger. The package combines four 6.0V 2650mAh Ni-MH batteries with an intelligent USB charger that reports charge status via LEDs, and supports both Micro-USB and Type-C inputs. For anyone who regularly shoots with compatible Durace and Raytheon models, this kit replaces old proprietary packs and keeps spare power ready without bulky charging stations.

Key Features

• Battery Capacity: Each Ni-MH battery is 2650mAh, providing extended runtime compared with smaller replacement cells for longer shooting sessions.
• Voltage Match: The batteries are rated 6.0V, matching the original spec required by listed camcorder and thermal models for safe operation.
• Smart USB Charger: The included charger draws 5V 2-3A input and charges at 6.0V 800mA, while the LED indicators show charging status and approximate battery capacity.
• Dual Input Convenience: The charger accepts Micro-USB and Type-C input and ships with a Micro-USB cable, so it can be powered from common power banks and USB chargers on the go.
• Compact Pack: Four batteries plus one smart charger means a full replacement set for devices that use DR10/DR11-style packs, reducing the need to hunt for single-use replacements.

Who It's For

This kit is aimed at camera operators, field technicians, and hobbyists who use camcorders and thermal/IR devices that accept Durace DR10 or DR11 compatible batteries; the 2650mAh capacity is useful for longer recording sessions or patrols where swapping cells quickly matters. The USB-chargeable charger also suits travelers who need a low-profile charging solution that works from power banks or USB wall adapters.

Users who need OEM-brand proprietary chargers with specialized docking contacts or very fast multi-bay charging should look elsewhere, and those requiring lithium-ion form factors or higher-voltage packs should verify device compatibility before purchase.

Pros & Cons

Pros

• High-capacity 2650mAh Ni-MH cells extend runtime versus lower-capacity replacements.
• Smart charger with LED status lights makes it easy to confirm charge progress.
• USB input flexibility (Micro-USB and Type-C) supports charging from many sources.

Cons

• The charger charges at 800mA, which is adequate but not fast compared with higher-current desktop chargers.
