Description
We now have smaller form factor blade fuse holders for 40 amp fuses.
Confirmed by manufacturer, these do handle 40 amp. Tested at 55.6 amp and running at 156 degrees C without failure.
These fuse holders feature 2x 3.3mm holes 27mm apart allowing you to bolt it to your chassis as a fuseholder or even a fuse/link combo.
The fuse should be installed on the positive line just after the battery.
Takes the standard blade fuses you find most common in cars.
Suitable up to 40 amp fuses at 32v. (Automotive) 1x 40 amp fuse is included. Additional fuses are also available from us.
For bigger power bots I recommend going for higher amp fuses (60/80) and using MIDI fuses either with a holder or bolted to ring crimps and insulated – available here
Remember to calculate the fuse rating based on your lipo battery C rating and choose a fuse lower than that but more than your stall/robot usage.
To calculate the fuse rating, take the maximum C value and multiply it by the number of amps delivered by that pack. A 3S 3000mah with a C rating of 45 will provide 45 x 3.0amps = 135 amps so a fuse rating of 100 or 80 will be fine.
That being said, I run my 2wd pusherbot on a 40 amp fuse. 20 amps blew out.
For higher powered fuses, check out my 40 amp midi fuses here: https://teamsc.co.uk/product/midi-fuse-holder/ The Midi style fuses can have 80 amp, 100 amp so better for higher ratings.
We also have our Fuse holders which are pre wired to 12AWG cable here: https://teamsc.co.uk/product/blade_holder/
