--EXTREME CAUTION PREAMBLE--
It is very difficult to fit this batterys into the box and wire them up. Open contacts will be very close when assembling. Short circuits can occure. Batterys can catch fire or explode! Please be very carefull while assembling and use some tape for isolating unessesary contacts!
Do not directly measure the length or your batterys with a measuring stick! Metal measuring sticks can short circuit the contacts!!
--END--
This is a housing to fit in 4 18650 lithium batterys in serial (4S1P). It has exits, spaces and canals to wire up everything internally. This model is designed for a total length of 131mm (2 batterys), check your battery length!! The length and space can vary depending on the manufacturer (and stuff life flat tops or soldering flags). You maybe need to resize the model for a perfect fit.
There are 2 versions provided, one for screws and one for adhesive. For the screw version you need 4 times M2x20 + 4 times M2 nuts. I did not tested the adhesive version myself.
RL pictures show the prototype.
Notes:
-Batterys maybe reach PLA glass transition temperature!
-Could also be used for 2S2P
