Default Green Horn Battery Builder

So I am building my 1st packs(IB4200's) and wondering what are the tricks to getting the bars soldiered real good to the battery?I've scuffed the battery ends and bars,and not having real good luck getting the soldier to stick to the battery.I put a dab on the battery real smooth then stick the bar on and heat it and it seems that the bar wont melt into the dab of soldier on the end of the battery.Any shints would be apreciated by the Greenhorn I know my iron is plenty hot and I am nervous about getting the battery to hot should I be?Hints???

Use a very hot soldering iron. I have a special one I use just for batteries because it is a high wattage one. Also use a chisel tip. The less solder used the better. Just enough to firmly connect the battery bar to the cell. Hope this helps.

230 watt gun with some Flux " No need to heat Battery long at all." 1st drop a little flux on the battery and bar, 2nd heat gun, Apply solder to battery and then apply solder to bar, 3rd grab bar with pliers and hold on battery and melt the two together with hot iron/gun. The flux will spread the solder real nice, Doesnt take much of either to make a great weld and you wont have to leave gun on battery long at all.

It's the small stuff that came with my Weller 40w Soldiering Iron.Not sure of the type.I am actually using my bigger iron(weller 200w).I use that soldier on all my deans plugs and motor wiring.Seems fine but not getting it to bond the bars to the battery real good like it I think it should.I will get some flux this morning and see if it helps.Should I look for a specific type of soldier?

try the flux.
i myself use kesters 60/40 "44" solder. a 1lb spool usually costs around $12.00. you can find it at a electronics store.

any 60/40 rosin core should work ok.
