Saw these the other day while I was shopping and they seem like a good idea. Anyone tried them?
I’ve seen various YT videos on “armour plating” your batteries but most seem to be adding more rigid layers, and I was thinking that the ideal solution would be something a bit more shock absorbing. These seem a step in the right direction, although I wonder if they’re thick enough to be all that effective.
I may have to try a couple, as I seem to be knackering my batteries on a regular basis.
If nothing else, coupled with the “Sticky Crappy Battery Strap”, they should improve the grip.
True, but I’m not sure how much of a difference an extra 12g-18g on a 600g+ quad is going to make to a pilot of my calibre, compared to the possibility of not trashing a £20-£30 lipo.
Assuming the weight:flight-time relationship is linear…
Say I normally get 5-minute (300s) flights from my 600g quad, which is roughly correct looking at what I did last weekend.
Time should be inversely proportional to weight (gets smaller as weight gets bigger), so T = C(1/W) where C is a constant, which for this exercise = TW = 300x600 = 180,000gs (gramme seconds).
So the theoretical time for 615g (add a medium-sized sheath and assume all other factors remain constant) would be 1800,000/615 = ~293 seconds.
That’s just 7seconds less flight time, which I think I could live with.
I suspect the ultimate truth is that if you’re slamming into concrete or steel at 60mph, any of these solutions are still going to transfer 99.8% of the impact to your battery anyway.
If you bottom mount the lipo and have a tpu ‘shark fin’ (for flip over) on top of the quad, it will be better. But make sure you land gently. When I swapped to top mount, I was / am trashing lipos quickly.
