Beetleweight fuses
entering bugglebots and found out i need to use a fuse
im using a https://www.ebay.co.uk/itm/222740285635?ul_noapp=true battery with a 5v 3a BEC. What type/rating do i need And would the fuse go before or after the BEC??
Cheers to anyone that can help

it would go before the bec so straight after the battery on the positive side
7.8.3 Fusing
A fuse rated below the maximum burst discharge of the battery MUST be fitted. The maximum burst
discharge current is calculated by multiplying the C rating by the capacity. E.g. 25C 2200mAh = 55 Amp
45 x 850 = 38.250 so be looking at a 35? or automotive 30 amp blade fuse?
35 amp blade fuses are available, they seem to be a pink colour from pics on ebay :)
Please someone confirm this rating :)
Posted the rules from feathers as this includes the formulae for others searching this topic in the forum.

Yes, I believe your calculation to be correct. ;)
I always put the fuse on the positive line as the first thing out from the battery. I use a 850mAh 4S battery and use a 30A (amber) automotive fuse in The Honey Badger 4.0.
