Looking to buy one of these for use around the house, but I’m not overly knowledgeable about them.
The Bose Soundlink Flex seems to have good reviews from the bit of research that I’ve done, but any recommendations from you guys on good ones to buy?
They’re very common in flashlights, including mainstream brands based in the USA (Streamlight, Surefire) and in a bunch of stuff from the Alibaba to Amazon pipeline. The former uses cells with added protection circuits, and such models will accept generic third-party cells. I’m a bit surprised I don’t hear about the latter exploding on a regular basis, but I have not.
Li-ion cells with protection circuits are safe enough for the average adult to handle without any special instruction; the risks are no different from the removable proprietary Li-ion battery packs that are common in power tools, and used to be common in laptops. There isn’t a safety reason preventing their use in other electronics like Bluetooth speakers, though the business incentive to produce a more disposable product is obvious. New EU rules mandate user-replaceable batteries in the future, though I imagine manufacturers will find ways to make it proprietary and expensive if they can.
