12v Lead Going To Almost 13v On Power Supply
Next question is: how much current can your charger deliver? BU-210a: Why does Sodium-sulfur need to be heated BU-210b: How does the Flow Battery Work? On December 26, 2015 at 1:02am Hassan wale m. To prevent the inevitable trip over loose wires, it's a good idea to make your wiring more permanent once you have confirmed the power supply (PSU) to work. http://windowsrefund.org/power-supply/cpu-power-supply.php
Ask a question and give support. I suggest you get a higher power capacity PSU, but first you should verify the accuracy of your voltage readings. Or add some series resistor to reduce the current until the battery voltage is near 13.6V and you can bypass the resistor. The battery does offer the advantage of powering the rig if the utility service is disrupted. http://www.techspot.com/community/topics/12v-lead-going-to-almost-13v-on-power-supply.28818/
12v Lead Acid Battery Charging Voltage
Good chargers with transformers can be transmitted from generation to generation of users, but switcher will work until some fan stop because bad quality or dust. See also #Technical Details. The picture at the top of this post shows one I have. The input just indicates 12v dc with no polarity.

But it will take time. Charge Battery With Power Supply So it is easy: you can use any micro-USB phone charger. Thank you for any help you can give me. Never allow a cell to dwell at 4.20V for more than a few hours. (See BU-409: Charging Lithium-ion.) Please note that not all Li-ion batteries charge to the voltage threshold of

http://www.webx.dk/oz2cpu/radios/psu-pc1.htm Or you can boost voltage from PC PSU like FvM suggest, that also can be one of solutions. 1 members found this post helpful. 17th August 2012,03:22 #8 DineshSL Advanced Don't throw your back out getting that very heavy battery into place. Theoretically you need something like 28…30V 175Amps to charge it in one hour. (because 175Ah theoretically means it can deliver 175A one hour long, so you charge with the same) But http://windowsrefund.org/power-supply/bad-power-supply.php There are 3-stage battery chargers out there, although they're a bit pricey.
If you have a female molex connector around, you can use the molex connector on the PSU directly for easy connection on and off. Charge Car Battery With Power Supply first were the ni-cads. Good luck with your experimenting! 73, Dave, KEØOG john Mac says: December 26, 2016 at 4:46 pm Hi from Nelson NZ.

Anyway, for charging li-ion, you cannot use the lead battery charger anymore. Also… Reading your other responses, it sounds like it has the potential to introduce some noise. Hi please check the battery terminal voltage if you are connecting fully charged battery it may not take more current.

Or you can use 2 pcs 1.5 ohm in series, each 10W. Be sure it's fully charged. So would you recommend me going for a cheaper GPU and buying a better PSU then? have a peek here However, once a break is introduced, this does become a possibility.
AS soon as it reaches 14.5V you need to disconnect manually. I have 2 sealed lead acid battery (70AH each) linked by a VSR charged by the alternator when the engine is running. So there are 2 possibilities: 1. The point of the exercise is not to be doing extreme flying maneuvers, but just to use it for playing around with PIDs and learning how they affect the flight of

No need to go to a higher voltage. 14.4…14.5V is for quicker charge, and can reduce sulfatation. BU-802c: How Low can a Battery be Discharged? Except…well, any good rig will work within a range of supply voltages. or you can see this project : AVR450: Battery Charger for SLA, NiCd, NiMH and Li-Ion Batteries http://www.atmel.com/Images/doc1659.pdf There are tons of project and designs, I cant post lots of them
BTW, the usual amp rating for a 100 watt rig is about 20 amps, so you'd be in the ballpark.
