Dear Members
For the past year or so we have been working on an exciting new battery technology, and we need your help to evaluate the business and pricing model. The short survey below has only seven questions and will take less than a minute to complete. Your feedback will help us make...
Hi does anybody have any recommendations for electronics design and consulting firms in the East Coast? I am trying to build a custom power supply using USB Type-C PD.
Thanks
Hi All, I need the help of an electronics engineer in the US to build me a custom battery charging circuit. I have drawn up all the specifications and have identified most of the components and the basic design. We are using standard TI chips to charge the batteries and the evaluation board...
I have an idea for an electronic project and I was wondering how much it would cost to hire a electronic design firm to design and build a prototype. Does anybody have any recommendations? USA only.
The project will involve fast charging batteries, MCU/logic and smart phone app integration...
I am trying to understand in in terms of Energy in vs Energy out. For a moment assume that we have an 100% efficient system that charges at constant rate.
So a
50 watt power supply @ 1 hr charge time = 50Wh energy storage
50 Watt power supply@ 30 mins charge time= 25 Wh energy storage
50...
When someone published battery capacity in mAH it drives me crazy. Most power bank maker like Anker publish in mAH assuming 5 volts output. so that was my assumption here.
But we do know that the battery capacity has to be 25Whr (based on the iphone X 3 Capacity claim) so charging a 25 Whr...
The funny thing is Indiegogo does not have any feature that lets you report this as a scam? there is no "Report this posting" link? Also You cannot post a question to the campaign unless you donate money.
Exactly!!! and it would be 20 amps at 5 + volts correct? ( based on the circuit diagram they are using multiple cells with balance charging). My guess is they are using 2 or 3 cell sin series which is 7.4 volts at 20 amps which will require a 150 watt power supply. Also what type of battery...
Is this another Scam from?

They claim to be able to fully charge a 5000mAh battery in 15 mins using a 50 watts charger???
Is that even possible? 5000mAh @5 volts = 25 Wh battery.
Assuming a 100%...
Actually that was my initial idea, we could use RFID tags to read the unique battery ID and look up the specs. but I am not sure how I can update the MCU memory using a smart phone APP. If I have to use Wifi connectivity will it not add additional cost? If Wifi connectivity is to be provided we...
Hi Frank,
My project is to add a small chip to every battery similar to this onehttps://www.digikey.com/product-detail/en/24LC00T-I%2FOT/24LC00T-I%2FOTCT-ND/857656. It can store the battery type in the chip, which is the micro processor can read and pull up the algorithm from memory. As the...
Hi, I am an amateur electronics enthusiast, I was trying to understand the inner workings battery chargers like Turnigy Accucell 6 Charger.
See Video:https://www.youtube.com/watch?v=3LfU4mjgpyM
My understanding is that there are no chips specific to Lithium Ion or NiMh battery. The charging...
