Have slightly more power are larger but weigh not much heavier.
I'm happy with it.

I Get 4 Swit Batterys S-8I50 with Swit S-2040 Led Light. It gives you about 1 hour on full light and more than 3 hours with no light. I first use Swit batteries for my sony 2 years ago and is a very reliable company. I also use the swit charger.

It is a fantastic battery, it also has a USB port for phone or tablet charging.
