Dive Xtras Sierra Battery Adapter

thingiverse

I purchased an old Dive Xtras Sierra that came with a dead NiMH battery. I ordered a PING LiFePo4 battery from China and then set out to create this battery adapter, which is a copy of Dive Xtras' expensive Power-Tool-Batter (aka PTB) adapter ring. The original Dive Xtras Sierra NiMH battery has 312 Wh capacity. The replacement has 600 Wh capacity. The replacement also heats up less, charges faster, looks sexier, doesn't release gas during use, has low "voltage sag" and supports higher current draw (which is why the voltage doesn't sag as much).\r\n\r\nI sat down to design this with zero experience designing 3D objects, so it has some "bugs", but in practice it works beautifully and cost very little to make.\r\n\r\nMore information can be found on my blog here: [Battery Upgrade for Dive Xtras Sierra](https://aquarat.co.za/battery-upgrade-for-dive-xtras-sierra)\r\n\r\nLet me know if you print this thing, it'll make me happy :)\r\n\r\n
