DIY 18650 6S battery pack help.

[delta_19]

So I wish to make a 6s battery for my long-board out of 18650 cells but i have no idea where to start. So far I have the following figured out,
the BMS: http://www.batterysupports.com/22v-24v-6s-60a-6x-36v-lithium-ion-lipo-battery-bms-pcm-pcb-p-478.html
the cells: http://www.alibaba.com/product-detail/wholesale-hg2-he4-he2-18650-battery_60294491545.html?spm=a2700.7724838.30.1.VGohG8 (or 25R if told other wise.)
and the charger will be a 6s lipo charger that im using to charge my zippy lipos.

I will be wiring them up in a two tall 6s4p pack for 12AH at 22.2V or in useful terms 25KM range at 20KM/h.


now the fun part well, fun for you...

is all this info right? is there better alternatives out there? am i going to blow something up doing this?

How will you be connecting them together? Spot welding, solder? Can't solder them without tabs and then must be very fast with the heat.

Most likely spot, might say screw it and solder. Seen a few videos where they solder solid copper wire to the cells with no problems.

I ended up getting 48 Samsung INR18650 25R5 cells and am going to be using the same BMS unless told other wise.

Now my new question is, with that BMS I run a lead off the first groups positive and that's my charge/discharge positive and then I run a lead from the last groups negative to the BMS then a lead off my BMS and that's my cells negative charge/discharge. Now would it be better to use a normal hobby 6s charger to charge this pack or to run leads in parallel from the packs - and + so that I have one with bullets for my board and one with a laptop style charger and then get a 22.2v 3A charging cable for it?
