In 7-8 years I’ve replaced a few batteries 
If you buy from a specialty store, they will give you an invoice, and you can make a claim there if it happens to explode, which I consider unlikely.
Has anyone’s MAG exploded? Or are we just the lucky ones?
For example, today, a 4000mAh Samsung 40T type 21700 battery, with a Dicodes mod, consuming about 15 ml in MTL, 18W, 23 boost. I took it off the charger around 2400 (midnight/early morning), the Xstar charger measured it as fully charged, but it’s still at 3.6V now.
I’m not worried about the dual 18650 VTC6 3000mAh batteries under my Asgard either, running at 85 watts, it might be unbelievable but it needs that much power
