NEEY 12-16S Active Balancer Vertical Mount

I wanted to mount my NEEY Active Balancer vertically because it fits the direction of my installed batteries and their balancer cables.

I designed the holders to use the existing screw holes in the balancer PCB and to also cover all the electronics in the front and back. The balancer with the installed holders can then be slid into a baseplate. This baseplate can in turn be mounted via M3 screws and in the end the balancer sits vertically.

According to the documentation the NEEY 12-16S Active Balancer has the dimensions 125 x 91 x 16mm.

Printing

• Filament: I used PETG
• Infill: I used 15% and the parts feel pretty sturdy.
• Nozzle: 0.4mm
• Layer Height: 0.2mm
• Perimeters: 2, (I used 1.67mm walls).
• Support: The front and rear holder need supports the baseplate doesn't. I used organic support from buildplate only.

Additional parts required

• 4x M3x20 SHCS screws to connect the holders and the balancer
• 6x M3 Nuts, four for the two holders, two for the baseplate
• 2x M3 screws in the required length to mount the baseplate to your desired location

Installation

• First install the rear and front holder onto the balancer.
• Mount the baseplate to the face where you want to install the balancer. Be careful that the screws do not reach too much above the baseplate, otherwise they will interfere with the holders.
• Slide the balancer with the holders into the larger slots of the baseplate and then move it 5mm sideways.
• You may need to remove a bit of material from the side of the dovetails of the front holder. Remove a tiny bit at a time until the dovetails fit nicely into the baseplate and have a good friction fit.
