Hi everyone,
I wanted to hard wire my dash cam using a power bank.
I have a Poweradd Pilot X7 power bank which allows for charging passthrough, meaning it can power devices whilst being charged itself. It uses Lithium Polymer batteries inside and has a capacity of 20,000mAh.
I have attached a basic diagram of how i want to wire it all up.
The idea, in theory, is that when the car is off, the dash cam can run constantly, being powered by the power bank, which can last over 24 hours by my calculations. And when the car is turned on, it can charge the battery bank, whilst it also powers the dash cam simultaneously - which is where the charging passthrough comes in. When the battery bank is being charged, there is no disruption to the dash cam's power - so i am not worried about that.
I have done some initial testing and it all works.
My worry is having the battery bank in the car, as I plan to hide it behind panels so that it all looks factory and hidden away. The worry is temperatures. I live in London in the UK, and the weather here is unpredictable at best, and temperatures vary a lot. Temperatures can sometimes in winter be below freezing like we've had for the past few weeks, and can be 25+ degrees C in the summer. Obviously in the car it might be much colder or hotter when the car is not being driven.
Any ideas or thoughts?
Thanks
