New to FE boats but not R/C electric. What is the reasoning for hardcase packs? I'm guessing for protection in R/C cars? Is there any disadvantage using them in a boat?
Thanks

Safety yes in cars. Not recommended in boats. We run higher amp draws and the hard packs can’t release the heat as well.Quote:

Yes... what Howard said plus if they are in a wet boat they do not dry out easy.
Used a couple Turnigy Graphene Hardcases in a P-Limit a couple summers ago. Split the plastic case open. Sold them to a car guy used at a big loss because they where useless for boats.
Maybe okay for sport boating, but definitely not competition with high amp draws.
Most hardcase packs that I've experienced have built-in 4mm female terminals. Not great for high amp draw FE applications. They do make a nice crisp "POP" when they split open 'tho...:laugh:
There are some cases with 5mm connectors and rated for 100C. I got four of them, Speedzone brand. I got 4 runs on them and they are measuring just under 3mOhm resistance. I use the hard packs because I need the weight distribution. I also run them in a HV configuration, so I don’t need crazy current out of them.
I know someone, (not me) who bought one of the new Traxxas boats and a pair of hardshell battery packs for it.with Traxxas connectors. These are proprietary connectors which Traxxas has chosen to use.
From what I've read here, I should now advise him to use different connectors as well as not use the hard shell battery packs.
For what it's worth, I have read that the Traxxas connectors are only good to 100 amp draw, and Deans were only good to 80 amp. I read it on the internet so it must be true! LOL
