Going to have a small initial batch of these kits available next week. This is a first run kit, so consider them beta, but this design is a progression based on previous designs we’ve been putting into use over the last year.
The kits will feature our new 4P 21700 Nickel Tab.
Here’s the PCB layout:
4P Frame w/ embedded nut
(updated 3d model coming soon)
Dimensions: 457 mm x 170 mm x 27.5mm
These batteries feature p-group frames that lock into the PCB via embedded nut + protrusion tabs & an FR4 bracket on the bottom side. This secures the mass of the cells directly to the PCB and reduces fatigue load on the nickel joints.
The main positive power output terminals also will come with an 80A bolt-on fuse.
More information on these kits will be available soon along with a build guide by our beloved @Benjamin
