Do different size Hailong cases use same frame mount?

[hartswood]

I currently have a Hailong 1 battery case fitted and am thinking of buying a Chamrider 19.2AH battery. The Chamrider battery comes in a Hailong 1.2 case. Do the various Hailong cases use the same mounting plate? I'd like to be able to swap between batteries.

From the Chamrider Aliexpress web site I get the following case measurements, all cm

Hailong 1 36 X 9 X 9
Hailong 1.2 36.5 X 11.3 X 9
Hailong Max 36.7 X 12.7 X 9

Even though some cases look the same, the connections in the base are often not, purchased two china batteries at the same time one had flat pins the other round the size is also different

Many thanks, measured my battery pack and realised I had the 1.2 size not 1. Will check pins carefully.
