Battery bank Definition and 14 Threads

I'm looking for a way to use these batteries that is safe and also useful. I've looked into buy inverters to turn them into portable battery packs but am out of my depth and don't want to create a device with serious potential fire hazards without thoroughly understanding the ins and outs and...

I need to build a battery system to drive a 10 HP pump motor. The actual BHP varies as the pressure in the system rises, but for the most part we are operating at a 10.1 brake horsepower. Run time requirements will vary from a few hours to many hours. I settled on 8 hrs as a basis. Motor...

Briefly, the problem; stolen bicycles are notoriously difficult to recover. Designing a GPS tracker to fit on one is challenging, because bicycles rarely have their own available power source. Whatever GPS unit is used must typically have its own battery as its sole source of power, which...

Hi. Could anyone guide me as to what equipment and considerations I need for maintenance charging a battery bank used as solar storage. The bank consists of 8, 6v deep cycle lead-acid batteries (Rolls batteries: S6- GC2-HC) The solar system is for a seasonal application and the shed they...

I have a 4.5v LED strip 14.5watts (unknown amp draw; maybe 3amp) 30 LED 5050 per meter that runs off 3 AA Alkaline batteries. It runs fine for several hours (with the AAs) which is great but Id like to hook it up to a small power bank. I pulled out an old old power bank of 2200mAh 5v 1A output...

Hello I drive for a truck company and am getting tired of being charged for idling my truck to keep my batteries from depleting. I have a 2000w inverter now that's hooked to the truck. I had the idea of putting a few deep cycle batteries and charging them somehow with truck inverter or outlets...

Hello, I have recently bought 4 cylindrical lithium ion batteries from hobby king to make a battery pack. To do this, I put all 4 of them in Parallel, so that the voltage would stay the same, but the capacity would increase. It says on Hobby king that they can charge at 5C, and since they are...

Hello, I have a bit of an issue and can't figure out how to find out the answer. I want to understand how to find out what battery I would need if I want to scrap the diesel generator I have and go for a battery bank. I have a 1250 kVA rated generator. PF is 0.85, Rated voltage is 400V, rated...

Hello everyone. So i live in Lebanon, and since a long time now we have constant power cuts, almost half the day each day. For that the Lebanese made up a system in which each neighborhood has power generators providing electricity to the residents when the power is out. Usually the owners of...

I am using a buck converter with a battery pack, for a usb charger. The issue is, is that the buck converter I have ( http://www.ebay.com/itm/DC-Converter-Step-Down-Buck-Module-7V-24V-to-5V-3A-5V-usb-output-power-adapt-/261030150117?hash=item3cc69bffe5:g:Q3UAAMXQTT9R0Qos ) has a led on it, which...

I'm in charge of designing a battery bank (using 18650 batteries) that will produce large amounts of heat for a short period of time. The battery bank will be in a near vacuum (~800 Pa), so convective heat transfer will not be effective. Since the operation time is only ~80 seconds, my thought...

Homework Statement A 48 V DC wind turbine is hooked up to charge a battery bank consisting of four 12 V batteries in series. The wind is not blowing, but the batteries must supply 2 loads. One is a light bulb, rated at 175 W at 48 V; the other is a heater, rated 1000 W at 48 V. The loads are...

Hello everyone and thank you for having me on the forum. I have a bit of a unique situation in which our very small machine shop is limited to one 20 amp breaker, and we have outgrown it. It is impossible to run more power to the building due to its remote location from any drop source...

I want to add a secondary battery bank to the hybrid and have that send a charge to the primary battery. I am considering 2 wind turbines mounted in the radiator inlets. I want to have the turbines charge a secondary battery that will feed to the primary battery. I am doing this to...
