Has anyone used the 3rd party batteries? Quite a few DeWalt knock offs on Amazon, around half the price of OE.
This comes up a lot, the answer as always is they might be fine, they might not and burn your house down.
They will not be using quality cells and rarely make specification.
I’ve seen too many horror stories of dodgy/knock off lithium batteries burning peoples houses down and killing family members to risk it.
It’s usually dodgy e-bikes off market places but I don’t see why they would be any different to dodgy power tool batteries off marketplaces.
Ultimately you are rolling that dice every time it’s plugged in. Particularly something that’s going to get bashed around a bit like a power tool.
I don’t even leave my official batteries charging overnight or unsupervised.
This is not me being some tin foil hat skeptic, I studied electrical and electronic engineering at college, I’ve got an electric car and a home battery storage system which incidentally are both outside! It’s just the risks of using knock off lithium batteries is real and they can be very dangerous.
I wouldn’t touch them with a barge pole.
Edit: I wouldn’t touch them with your barge pole let alone mine!
