Hey folks, Ive been building electric bikes for past 8years… So I have some experience with building small battery packs…which can be wired in series for higher voltages… below is a pic of a 5S4P pack I just built… Custom sizes can be made…
This is very inexpensive to build… no soldering… no welding…
I am going to buy brand new 18650 cells (NCR18650GA 3500mah) from a trusted Hong Kong supplier I have purchased 18650 cells from this company previously and 100% confident they are genuine cells.
I am located in Canada and ship to Canada ONLY. Shipping can be choosen and calculated at a later time for each person individually. I planned to buy the cells early in the new year 2017. if you are interessted write me a pm!!! Then i will update this post with the summary.
Official specifications: Rated capacity: 3300mAh Minimum capacity: 3350mAh Typical capacity: 3450mAh Nominal voltage: 3.6V Discharge end voltage: 2.5V Charging current (Std.): 1.675A Charging voltage: 4.20 +/-0.03V Charging time (Std): 4.0 hours Continuous discharge current (Max.): 10A Internal resistance (AC 1kHz): <38mOhm Cycle life: 300 cycles to 70% Weight: <49.5g
Current price per cell: $3.10US
We are Up to 150 cells - with UPS shipping + fees and duty estimated @ $6-7CND per cell + Canada Post delivery fee
Also I began a build thread for people to check out here http://www.electric-skateboard.builders/t/solderless-5s5p-pack-build-with-18650/15663
