I'm putting together my first ebike build out of an old mountain bike. I'm assembling the battery pack from scratch using salvaged 21700 cells. I don't imagine many people install fuses on their battery packs but given how violent these unprotected cells could be in the face of a short... I would sleep better at night if mine had one. Trouble is, I am having difficulty finding a suitable fuse. The vast majority of fuses I can locate online are automotive/marine/audio fuses usually maxing out at 32V. The pack I plan to build will be 14s lithium ion, and thus tops out at 58.8v. Has anyone else done a battery pack build with fuse? What fuse type/rating did you use? Where did you buy them? What brand?
Any info would be appreciated.
Thanks!!
Holy shit this is kind of unsettling. Though I would expect ALL major browsers to reject reading any local files like this..... would this kind of thing actually succeed somewhere/somehow?
Approx 30 mins ago, I suddenly lost access to lemmy.ca due to DNS resolution failures. I've managed to restore access by tossing the known good IP into my computers hosts file, in order to make this post.
It's worth noting I'm running my own DNS resolver (via PfSense router/firewall software) instead of the typical DNS forwarder offered by my ISP. As a result, my DNS ecosystem is likely a bit more fussy about the "correctness" of the DNS configuration.
My DNS server logs some entries complaining about DS and DNSKEY
debug: Failed to match any usable DS to a DNSKEY. info: Could not establish a chain of trust to keys for lemmy.ca. DNSKEY IN
An attempt to verify the domain name using delv results in the following:
delv lemmy.ca ;; broken trust chain resolving 'lemmy.ca/A/IN': 127.0.0.53#53 ;; resolution failed: broken trust chain
Running an external DNSSEC check tool, currenly reports DNSSEC related issues. The tool I ran was:
https://dnssec-analyzer.verisignlabs.com/lemmy.ca
This gave me two issues:
None of the 2 DNSKEY records could be validated by any of the 2 DS records
The DNSKEY RRset was not signed by any trusted keys
Did something related to DNS get deployed in the last little while?
In any case, I've got a workaround in place and am not stuck, however a site admin may want to be aware of this information.
Thanks!!
