Hi, From what I understand Li-ion batteries are very sensitive to charging voltage control. That's why some of the hoverboards and the recent phone fires are suspected of being caused by. I will however make no comment about the one linked, it's made in China so lets not get our hopes up.

There are 2 types of 18650 batteries, one with overload protection built in and one without, there is a physical difference between the two types and the battery with overload protection is slightly longer.

If its not a reputable brand then assume no overcharging protection as this is where they cut corners, ask Samsung phone users.

Look at people such as Maplins, at least you get expert advice and the correct charger and a safe to use one.

Expert help? Maplins?



Oh, and

The last time Maplins were any help, in the 1980s, they were a mail-order components supplier based in Southend. Ever since they turned into electronics box-shifters they've been staffed by students, hardly any of whom know anything at all about electronics, let alone whether Product X is better than Product Y or whether either would suit your application.

Apart from that, yeah, experts

When they had just one shop in southend the staff were excellent, if they didn't have a component in stock they could calculate the equivalents to make up the value. Now the place is a joke.

i remember that store I think

 

[WorkshopChris]

When everyone else at school was off buying new football gloves or cricket pads i was always in there getting reels of cable, resistors and building the kits they used to do. Trying to interface stuff with a ZX81.

you use a 5v power supply. you can use a standard 5v USB one as there is a connector on the board. the 99p bit is the charge contoller

If you can wait a day or so, I may have a 12v/ mains charger you can have.
