At least, I surely hope so – the alternative is that they’re knowingly selling a LiPo-powered truck with a dumb charger, which is probably grounds for dragging them into a criminal court.Īll that said, if you want to charge LiPo batteries in the safest way possible, a smart charger (available for as low as €40, though better ones cost more and are a good idea) is a much wiser investment than any homemade contraption. My guess is simply that whoever told you the six hours thing doesn’t know a charger from an iron. If it uses a Lithium-polymer battery, then it most certainly has a charger capable of figuring out when the battery is full, because otherwise it’d catch fire long before six hours passed. If the truck is using a nickel-based battery, then leaving it on for more than 6 hours isn’t going to explode anything. Reposting here what I posted in his site… Posted in Arduino Hacks, home hacks Tagged arduino, lcd, timer Post navigation As with his previous hacks, has provided plenty of documentation in the form of pictures, code, and even a video of the timer in action. To make things easy for his son, he added two buttons to the front of the controller – one for selecting the amount of charging time, and one to set the timer in motion. He grabbed a project box and wired up a nice looking socket timer, complete with an LCD status display. Coming up empty, he decided to create his own timed electric socket regulated by an Arduino he had sitting around. With grave warnings from the manufacturer dancing in his head, he searched around for a timer that would allow him to cut power to the battery after charging for its allotted time. Santa brought son a shiny R/C truck for Christmas, but this new toy had one drawback – its batteries could only be connected to the charger for a maximum of 6 hours, lest he turn his house into a pile of smoldering ash.
