The Dong Cheng 40V Brushless 16 inch (41cm) Chainsaw is the number 9 pick in our cordless chainsaw guide. It is a battery-powered saw with a 16-inch bar, a quoted 14 m/s chain speed and a brushless motor, sold as a kit with two 4.0Ah batteries and a charger for £149.99.

The finding on this listing is the voltage. Dong Cheng calls it a 40V saw, and then its own copy describes it as running on "dual 20V (40V total) batteries" — so the 40V is the two packs added together, not a single 40V battery. The rating is the other number worth reading twice: 4.0 out of 5 from 64 ratings, which looks solid until you see the split behind it — 58 five-star ratings, but also 10 two-star and 9 one-star ones, so 19 of the 64 sit at 1 or 2 stars. Everything on this page comes from the Amazon listing rather than from any testing we carried out.

**How many cuts does the listing claim per charge?**

The copy claims up to 120 clean cuts through 4x4 lumber on a single charge using the included 4.0Ah batteries. It also says to fully charge both matched 4.0Ah batteries before first use to balance power delivery.

Yes, according to the listing. The Dong Cheng DCCS40161 is part of the DongCheng 20V and 40V platform, and the listing says the batteries are interchangeable across that lineup.
