I admit it is unlikely that the Spencer Davis Group was referring to our new battery management design, but after a lot of development effort we have now received our new circuit boards from PCBGOGO. They have done a very professional job of manufacture and assembly. Luckily for us it also works as intended, so well in fact that we’re wondering if people might like to purchase this board separately for their own projects! Despite the plethora of battery power supplies around, none seemed to be designed with all of the basic requirements that you would expect, deliver high power and be at a reasonable price. Even my favourite DVD player has an ON/OFF button that doesn’t work when its software has crashed!
Designed to screw in underneath a Raspberry Pi without soldering, it supports up to 2 18650 Lithium cells with over-charge, over-discharge and over-current protection. But it also provides accurate battery voltage and current monitoring for software (showing charging / discharging), a button interface with software shutdown control as well as a hard reset feature. Designed to maximise battery life, it can also deliver enough current for high power applications with separate terminals for ancillary devices.
We’ll be making more details available, but you’re welcome to let us know if you might be interested in purchasing a board, and what projects would be ‘Alive and Kicking’ with a battery power supply!
As we look forward to the new year with more hope than perhaps ever before, we’re also hoping our product launch is not too far away now. As ever, stay safe!
