This is a continuation update post to this thread:
I am selling some brand new 10s4p packs
They are made with sony vtc5 2600 25a cells. The packs include a charge only bms, a detachable 2.1mm dc jack charge port (the standard on most packs) and a 5a fuse installed.
it comes with a spare 3a and 5a fuse as well.
I accept payment through paypal.
the price is $310 shipped anywhere in the continental USA or, $300 if you use friends and family payment.
all batteries i make are double insulated in fish paper and kapton tape, every possibly short point has been wrapped multiple times. all cells have a fish paper gasket on the positive end as well. the edges of the pack are abrasion proof as well. below are some pictures showing the quality of the packs
The p groups are glued with high temp hot glue to prevent it getting soft if the cells are running warm, they are then wrapped 3 times with fiberglass tape. by wrapping it 3 times, if 1 were to be damaged/cut it wont affect the structural integrity. they are then wrapped in fish paper.
from there, the first welds are placed using 10x.2mm nickel strips. i dont have a picture, it was too pixelated, but a layer of fish paper is added between the bend for extra dampening and short protection. the tab sticking out is for balance leads to be soldered on.
lots of groups made at once and welds are inspected for quality. (this photo is before the fish paper is added to the bends)
The pack now gets assembled into its final form. the welds are place and then braided flat cobber cable is added where needed to increase ampacity without adding thickness. the power cables are soldered across and entire p group to insure a solid connection and to not bottle-neck the power output with too small solder points. All soldering is done with an extremely powerful iron so the temperature of the cell never gets very warm at all. soldering takes less than 1.5 seconds with pretinned cables. (sorry for pixelation on some photos, i have condesation on the inside of my phones camera lens)
these packs some with heatshrink as well.
the packs themselves are the following dimensions
2 piece(s): 15.25in x 5.75in x 1in
1 piece(s): 13.75in x 6in x 1in
both are the same price. if you buy them, they will be shipped within 36 hours of purchase at most with shipping that usually takes 3 days, but up to 5 at most. Tracking number is provided I only ship within the continental USA to avoid extremely costly hazmat labels and storage booking
interested? claim one in the chat and pm me to finalize it!
I also make custom packs incase you need one. just let me know. i try and offer the cheapest prices around and i can make them from almost any cell with a little bit of lead time.
they should be rounded off to prevent shorts
