Just reposting from reddit, but this battery compartment is brilliant. Perfect execution considering the form factor:
Dual fuel capability is a huge practical bonus, especially for a camping lantern where recharging is impractical.
That 1500mAh capacity 18650 battery is stone age, though. For $5 you can easily have more than double the runtime with a quality cell (3000-3500 mAh) from liionwholesale.com.
That’s not mine. Just reposting cuz I thought it was cool. But I agree, I wouldn’t use or trust that battery. I have enough quality 18650s so whenever I get a mystery low-capacity cell inside a cheap item I drain it and dispose of it.
