I'm sure many will consider me a Nervous Nellie but where practical I put in line fuse holders in my models as close to the battery as possible. Perhaps not in every last model but all my 1/10 ( some use 2 5000mAh packs in parallel) but I fear shorts. Perhaps the belief
in fuses is just a pipe dream but I'm hoping they'll head off some problems.
NiMH and certainly Li ion batteries just can't be taken lightly. I'm certain the original poster took all preventative steps but even the best intentions can't always counter the unexpected.
