Mounting a midi fuse holder and a battery switch in a waterproof box …
↓↓↓ Complete description, time index and links below ↓↓↓
I need to take a Chinese electric trolling motor (links below) with a cheap Chinese 25.6V/50Ah LiFePO4 battery (link below) out on the lake to take some measurements. Call me paranoid, but I want a battery switch and a fuse between the two.
First we mill two studs inside the box away, because they are interfering. Then we drill four bolt holes and a large hole into the box for the battery switch. After drilling two more holes for a cable gland and a terminal we do some dry fitting.
00:00 Intro – battery switch, fuse holder and IP68 enclosure
01:57 Drawing (1) – holes for the battery switch
02:41 Milling – removing two studs in the enclosure
03:48 Scribing (1) – the positions of the holes
04:17 Drilling (1) – a 62mm hole with an old hole saw
06:58 Drilling (2) – four 5mm holes for bolts
08:09 Result – the battery switch fits, but only just
09:30 Placement – of box, fuse holder, input and output
11:41 Drawing (2) – holes for terminal and cable
12:09 Scribing (2) – the positions of the holes
12:24 Drilling (3) – an 8mm hole for the pole bolt
14:12 Drilling (4) – a 16mm hole for the IP68 cable gland
14:57 Dry fitting – it’s a tight fit, but I’ll make it work
17:47 Wrap-up – next is adding gaskets and wiring up, bye
