Same Fiido, same battery space, two years between builds. We built one in 2024 and another in 2026, with the same outline and layout.

Dead Pack, Blue Bin? Confirm Wrong Sia
A battery pack does not belong in general rubbish or the blue recycling bin; ask the maker or authorised service how to dispose of it.
-
Smoke From Battery? Don’t Film — Get Out
If a battery is smoking, raise the alarm, get out and stay out, then call 995.

Same Plug, Different Charger? Don’t Assume Can
A connector that fits does not prove a charger is right for a pack; use only the charger specified for that pack.

Rain Kena Battery? “Dry Already” Also Stop
Water may damage a battery even when the outside is dry. Stop using and charging it and get it checked.
-
“Small Crack Only” — Seller Say, You Stop
A crack is visible damage, however small the listing says it is. Stop using and charging the pack and ask the maker or authorised service.
-
Pack Getting Fat? Stop Using It Lah
If the pack is swelling, stop using and charging it. Ask the maker or authorised service what to do.

A rushed secondhand deal is no reason to skip questions; outside appearance and paperwork cannot prove a pack is safe.

Friend Opened One Before? Still Don’t Open Yours
If a pack looks suspect, stop using and charging it; your friend’s old story is not a reason to open yours.
