Battery charger for hilti cordless drill

[pil]

Hi,

I have a very good cordless drill but i lost the charger and I want to build a new charger for it. Can you help me with a schematic for the charger? I took a couple of pictures to the drill so you can know what kind of battery uses. All the charger schematics on the internet are for small AA batteries.

Thank you.

The second attachement wasn't working so I put both photos directly :

The link below shows a diagram with a simple charger based on a LTC4060

Will using a only 2 banks of a 3 bank charger do any damage to the charger? My boat used to have a 36 volt trolling motor now it has a 24 volt. I want to take the extra battery out because it has no use.
Thanks
