ISDT C4 4x 18650 Adapter

thingiverse

An adapter to 4x18650 cells instead of 2 Parallel to load / Analyze. Only the adapter requires support material ... The safety limit for the load capacity must be disabled, since max 2000mAh are charged in these slots due to the normal size intended for this purpose. Perfect to handle larger amounts of batteries and despite performance losses almost twice as fast as with 2 slots... Loading via these slots is possible with max 1x1.5A or 4x1.5A, unloading with 1x1A 2-3x0.8A 4x-0.65A unfortunately the maximum what the device does!!! I tried to connect 6x Parallel, but the device is not suitable for that. Unfortunately, I had to replace the springs in my case because they had a very high internal resistance and were hot, with proper springs certainly possible, I subsequently ordered the following contacts => Keystone 209 (https://www.conrad.de/de/keystone-209-einzelkontakt-1-mignon-aa-a-cr-2-cr-123-steckmontage-b-x-h-792-mm-x-1209-mm-651022.html), for non DE/EU (https://www.digikey.com/product-detail/en/keystone-electronics/209/36-209-ND/151583) otherwise I have added a blank file to accommodate his own contacts... For your use, I have only M3 screws with nuts taken and sanded flat after grinding on the grindstone and then polished with emery paper.
