"removed it from the Xiegu case. "
Measure its dimensions, carefully, and check Amazon and AliExpress for ones likely to be compatible.? With Amazon, try to be sure it's returnable if it doesn't fit.
And post and all the specifications and measurements that you take or find!
From earlier messages about the battery, it appeared that the dealer in England could get them, but not ship out of the country.? You could try to find someone there, or in Europe, who could buy one and ship it to you.? I believe that there's also a Facebook group for the X5105 - maybe there are members in England who might be willing to help.
