hi!
recently, i was charging my cordless drill battery, and there was fluctuation at home, and the charger blew.... 
now i cant use the drill because i cant charge the battery... searched around in shops for another charger, but no luck because it's a chinese drill and they don't keep stuff for these...
so i was wondering, can i connect my LiPo to this? it is a 12v drill, so if i connect my 2200 3s 25c, can i use it? or will i need one with a higher discharge?
 or is there a way to charge the battery with my lipo charger? i have an accucell 6,

here are some pics for better reference

this is the battery:


and this is the points inside the drill(left one is +ve )


and these are the points on the battery... i cant figure out how to charge it, because i dont know what to do with the "ground" pin...



thanks !

Try it on the charger, at low amperage (< 0.5) at first . The charger should automatically detect number of cells.

You could also get the original charger repaired. If you know the charge rate & trickle rate you could buy another charger

@sanjay sir, what battery type do i set it as? its got these cardboard like cells inside,, but nowhere does it mention what battery type it is

Your accucel can easily charge this pack -

To identify battery type count the number of cells
If 10 nos then its either NiCd or Nimh - to be on the
safe side charge at Nimh setting at 1500 mah charge rate.
If 3 nos then LiOn - charge at you normal Lipo setting 3s
Seeing the drill quality - it is unlikely to be Life

you can also connect your lipo to the drill - the original
pack is 1.5 ah or 1500 mah so your 2200 mah pack
should easily be able to power your drill.

Saikat has good advice
