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.
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.
Thanks for the reminder, intended on including it.
The vertical height right now is equal the height of the frame as I currently have it protruding about 3mm through the bottom of the PCB, so it looks like we could bring it down to about 26mm or so if we needed to shave some height.
I’m in the planning stages, sometime around the first of the year I’m going to build a replacement (upgrade) battery for the Kaly, so it needs some flex if’n I use your Kaly notched PCB, but I see it really isn’t designed around flex…
should I just plan on buying 4p brick pcbs or do ya think that the 12s4p pcb will fly?
I have something special in the works for the v2.0 12s4P “Kaly style” FlexPCB.
I am going to build one out myself before I pitch it too hard, but happy to share my details as I progress. It’s nearly finished, I pushed it back for a redesign because I had an idear to fix my concerns over the flex aspect.
Think 3 separate modular PCBs that hold 16 cells (4x 4pgroup) on each, connected via bush terminal & 10ga cable + flexible balance connectors.
I have my poor gutted KalyKat (DIY Kaly 2.0) sitting here unloved and empty of battery, so I’ll be fitting everything into a stock 2.0 enclosure on the OG Kaly XL deck for this.
Shouldn’t be long on this one either, hoping later this month.
In theory you can use the same PCB with an updated P-Group frame to build a 12S8P doublestack. I want to try this out but need to build & test it myself before considering it as a product offering.
Yeah those ones that Quinn said, for sure. In esk8 we need cells that both have high discharge and have high capacity. Those dont come cheap, but there are some really great options for 21700’s, more so than 18650’s.
