Easy to use hand held, cordless saw to cut fence?

[Greenwitchart]

I am looking for advice on what I could buy to do some bits of DIY in the garden including cutting down the top of a wooden fence that is sticking out ( was added to the main fence by previous owners to support some roses).

I am looking for a basic, not to heavy hand held, cordless saw that I could use.

Could anyone recommend something?

I would also use it to cut branches and some planks of wood to make a small garden bench.

I am looking at B&Q, Screwfix but not sure what to get...

Whenever I've needed to do anything with fence panels I have always used a hacksaw to saw through the nails and then removed the panels.

Working with power tools at height, you need to be very careful obviously as sometimes the tools can buck aggressively if they hit things, especially metal fastners.

For branches I have a kind of curved handsaw blade on a long pole which is great for chopping high up stuff without leaving the ground.

I bought this saw. DH laughed at it when it came but he soon changed his tune when he started using it to chop down a small tree, cut up fence panels, etc etc!!!!!!
Has a battery pack that you charge up. it small and lightweight and has a shield guard for safety.
