Hi everybody,

We are trying to change the original battery (out of order) by a DIY LiPo external battery on the Bosch GBH 36V cordless Hammer.
Somebody knows how to connect ? If we connect only the two battery slots +/- we don't have current and the hammer don't run. What to do with the third battery slot (between + and -) ?

Many thanks and sorry for my bad english : I'm a french caver.

Cheers.

Hello,
my club is also interested in upgrading bosch gbh 36V drill. Which battery did you use? Where did you buy it. I got a proposal from local company for 290?: 36V, 11.6 Ah, li-ion battery. But I wonder if there is any cheaper alternative.
