How easy is it to convert the different types of solid posts on forklift type bats to bolted connections?

I know that Billi was going to do one

Unfortunately they are welded terminals, but I will drill and tap the terminals to take buss bars on the 12 cells that I will use.I noticed on a photograph on this site that one installation had used this system to overcome the welded terminals.

did you do it in the end?

Any pics?

I cant find the thread you mentioned. There does seem to be a few types, some look easy to drill cross wise & bolt but others look quite shallow & poss need vert drilling & tapping. Would a tap in lead hold ok?

hi justme,
        the cold does indeed hammer the batteries, not only do they loose the charge but they refuse to take it as well, for a while during the freeze i thought my 20 piece powersafe and 20 piece yousa had begun to degrade but within days after the place warmed up everything was back to normal, the banks are stored in a specially built brick house,only moderate insulation but i was forced to depend on our nixon geni for the first time in 2 years.
                your other post in which you asked for a method of connecting your batts,i got this advice from a forklift expert.
   get yourself a hole saw,the type with the round circular hacksaw blade with pilot.find one with a diameter to match the normal round battery post,
        flood the cells in question to the top with distilled water,put a cover around the area you are working on,work in a well vented area the hole saw will cut through the lead like butter,take it slowly,each post take only a few minutes to do, disconnect everything,dont do the job while charging or just after a charge. play safe.i would also like to add that i myself have not done this as yet,i discovered i did not need to, but i would,nt hesitate to use this method.
