18650 battery for Quansheng UV-K5, K5(8), K6, etc.Battery case with contacts for stock charging base, place for 2S BMS:https://www.aliexpress.com/item/4001051801172.htmland 2S active balancer:https://www.aliexpress.com/item/1005005354464538.htmlIt uses Keystone 1017-1 battery contacts (you just need to cut pin).https://www.mouser.pl/ProductDetail/Keystone-Electronics/1017-1?qs=wOxb8XianXhq6%252BfB2t0c2Q%3D%3Dhttps://www.tme.eu/pl/en/details/keys1017-1/batteries-containers-and-holders/keystone/1017-1/https://www.digikey.com/en/products/detail/keystone-electronics/1017-1/4499386Battery contact for the radio is made with etched PCB.For release button sprint I've use 5mm OD, 10mm long spring:https://www.aliexpress.com/item/1005005312536098.htmlCharger base contacts are made with 0.1x5mm nickel strip tape.There are contact_form_A and B files so you can form those contacts.I recommend printing it with ASA as it's UV resistant (unlike ABS) and it's easy to glue parts together. Just use some ABS/ASA dissolved in acetone.PET-G can be used but it needs good glue.!! IMPORTANT !!If you put BMS then when you remove cells, BMS will shutdown. After putting cells back in it will remain in shutdown state until you will connect battery to external power (charging base or USB).03.03.2024 - done few tweaks. On important difference is that battery release button is smaller.16.04.2024 - modified charger contact cover for easier printing.
