Building a 4S2P Lithium Ion 18650 Battery with Vruzend 1.6
JLCPCB Prototype for $2(Any Color): https://jlcpcb.com
My biggest 18650 lithium battery pack using the Vruzend 1.6 system. Assembly can be very modular if you get all your dovetails and slots in the right place! I made a little bolt-holder jig to facilitate tightening of the barrel bolts. BMS and balancer boards to be added soon.
