2 x Hawk Woods BP-75U camcorder batteries. They are in excellent condition, and have had very little use. they were bought for my Sony PXW-X160 camcorder that has done just 50 hours.
Here's the technical info:
The Hawk-Woods BP-75U has been designed, manufactured and tested to be a direct replacement for Sony BP-U type batteries.
With a built-in fuel gauge & Hawk-Woods build quality, the high-tech Li-Ion BP-75U camera battery offers stunning performance for its size and weight and unlike many replacement BP-U batteries on the market, the BP-75U uses the original battery contacts to provide power, rather than a flying lead connected to the devices DC power input.
The BP-75Us built-in Total Battery Protection system offers over discharge / voltage protection (If placed on unsuitable / incorrect charger), short circuit protection and thermal protection.
