901b With Penstyle size batt?

[bribri]

Surely their must be a supplier who has a 901b with an extra long lasting size/style battery.. Anyone know who has it? I would like one just to take my 901b out on long drives for.

sounds like you want a Janty Dura mate...

If you are in the car that long another option is to get a car USB adapter and a usb passthrough battery. .
