How do i install ARK-4 on a PSP 1001 without a battery.

It has 6.60-PRO-B10 , it says that i need to upgrade to 6.61 to install ARK-4 on it.. I think its model 01g and its an PSP 1001 atleast thats what it says on the model no! And i dont have an battery which i take all the risks that this proccess can brick my PSP and i dont care if it bricks or something but it would be cool if it had modern jailbreak on it and yes i tried BatterySpoofer plugins and it didnt work at all... Thanks!^^
