Where to get 10 cells battery packs?
 

Just wondering where would you buy 10 cell packs for a e-maxx? Would they even fit in with gorilla straps.

yea, they would fit but you would have to make them with 8 flat and 2 ontop

Mike can make you a few packs of the IB3800's.

anything is possible!

What do i need to put them togeather myself? I know i need the batteries. jig to hold them, wire, connectors and battery bars. I've tired to put them togeather before but solder did not want to stick to them so i'm guessing they weld them of some sort?

nope, just solder. you have to put a little on both the bar and the battery or it wont stick.

You also have to make sure you use a high enough wattage soldering iron. 60-100W should do fine

My soldering iron is cheap so it's probably not hot anough. Is there any good how to's on how to make a good battery pack?

This one would probably do what you need:

My soldering iron is 23W lol

just sand the ends of the batteries and the bars slightly, then use flux.

What's the flux do?

allows solder to melt at lower temperatures and makes it stick to the surfaces. Its very hard and stupid to solder without flux (resin)

Where can i buy flux? Do you mix it with the solder or what?

btw how do you charge a 10 cell battery pack? My chargers max is 8 cells

well i guess you wont be able to charge one.... gotta get a charger to charge them or reduce your cell count... if you get another i would recommend the astroflight 112dx.

Where do i get flux?

That charger cost a lot plus i would have to buy the 12V power supply. Do they have any twin chargers like the super brain 977 for high cell counts.

I had a 40 Watt iron and a 100 watt soldering gun from Radio Shack. Neither worked and I thought it must be tough to make a good set of batteries. MetalMan confirmed these weren't good enough from the problems I described. I bought the $10 60Watt soldering iron and resin core solder from my LHS. Works well! For reference, the iron is Hobbico and the solder is Kester rosin core with non-corrosive flux.

the charger isnt really expensive for the specs but the new 989 is another charger to look at. its ac/dc charges lipos, 20 nimh and the whole shabang...

So was it the solder that made a differance? I can never ger the stuff to stick to the battery guess i need some sand paper.

A little flux on the battery then a good soldering iron with solder will work. I use a 100 watt iron myself. I have put 13 batteries per side of the gorilla chassis. Before you get to far you need a charger. I like to discharge my cells before soldering to. .9v per cell is fine for discharge.

I doubt the 23W iron you have will work. The 40W iron I had couldn't even separate the 7cell EMaxx style packs so I could make them into flat packs. The iron was the important item for my situation. I just used the corner of a flat blade screwdriver to scuff the faces I was soldering. As mentioned, apply a dab of solder on the battery bar and the the battery first and then heat is only needed to finish the solder joint.
