Just got a battery from Smudge this morning (thanks btw) for trouts light when it arrives.
Cost was £46 for a 14.8V 2.6Ah battery plus £23 for a charger. This will give around 2.5hours on full power (full being 2000ish lumens). There is also a 14.8V 5.2Ah battery at £83, plus £23 for a charger. You would need to add postage on to this.
This is my 2nd smudge battery and I'm very, very impressed with the quality.
So to recap for under £250 you're getting the best light/battery combo available with insane amounts of power on max from two very helpful, decent guys.
And it's even going to have a fancy laser etched fish on the side.
Basically one complete package like most manufactureres offer as standard.
But what other sellers are offering a light/battery combo of this quality throwing out anywhere near 2000 lumens for £250. The lupine betty for example is £650 and thats 1500 lumens.
You really can't expect to have it all.
Maybe trout should stick it in a fancy box, throw in some instructions and charge £500.
