Whites 5900 di pro sl lighter battery pack

[akille68]

Hello,
Anyone know which kind of li-ion battery should fit a 5900 di pro sl making a lighter machine?
Originally it has a 4 C cells battery system. I would like to mount on a lithium rechargable pack.
Any advice? Thank you.

I thought to buy a battery pack like the one in the following link (and specific charger)

This batteries are less dangerous than lipo ones and erogate 6,6 V. Some are lighter than the original battery pack (350 gr.). The problem is that I donno if nominal 6,6V will damage my 5900 that needs only 6v...

Now, I would like to know how to check polarity of battery pack to do the mod. Maybe this procedure could work well:


Place multimeter probes on each side of the battery. If multimeter display reads a positive number, then the polarity on the battery matches the positive and negative probes from the multimeter. If display reads a negative number, then you need to switch the probes around on the battery. It should now read a positive number, and the polarity of the battery now matches the polarity of the multimeter probes; red is positive, black is negative.


Anyone can help?


Thank You.
