So far this battery is the only one that even fits into my DLG with 2s. I've been looking for one like this for weeks. If it were 2mm longer, I wouldn't be able to push it into the battery compartment. The width shouldn't be much larger either. It also weighs less than my 4 round cells combined and has a larger capacity. However, I had to add a small 4g regulator to get the voltage back to 5V, otherwise the servos would fail. So a product that many DLG users could definitely use. And the price is right too.
