For those who want a big, high-energy-density battery for a challenge, scooter batteries are a great supply. They’re usually 48V batteries with capacities of 15-18Ah which is various energy! A selected battery kind is gaining recognition — the RPH0002 — which is pretty simple to search out new or second-hand. Nonetheless, it has an uncommon connector and safely attaching to it basically requires a bespoke board — and that’s precisely what this DIY RPH0002 Connector Board is for.
The connector comes as a equipment that it’s essential to solder collectively. It’s a intelligent design, utilizing ENIG plated PCB for the connector pins, and including each a fuse in addition to energy and information connectors. Not like most batteries, the RPH0002 has some smarts inside. It is advisable talk with it over CAN to allow energy output and to maintain it energetic. This may be simply achieved with CAN libraries or with one other board by the identical vendor — the CANarchy management board.
As soon as soldered up and linked, you may energy your challenge immediately or join a buck converter in-line to drop the voltage down to three.3/5/12V or no matter your challenge wants. With the effectivity of a switching controller and the ability density of those batteries, small IoT initiatives can final for months on a single cost whereas nonetheless having the ability to draw massive bursts of excessive present if wanted for RF amplifiers! Add a photo voltaic charging system and also you’ve acquired a complete energy resolution that may final even by means of lengthy durations of darkness.
