Quick Question On Battery Charging

i have a 12 volt quick charger from power wheels. tvtech, Aug 4, 2013 #11 jst3712 New Member Joined: Sep 28, 2008 Messages: 60 Likes: 0 Location: Melbourne, Australia jst3712, Aug 4, 2013 #12 tvtech Well-Known Member Most Helpful Member I have become slacker over the years...moaning does not help. So say you start with a 5 ohm 5 watt resistor. http://olivettipc.com/quick-question/quick-question-about-ram.html

Mavician posted Feb 22, 2017 at 1:15 PM Which Drone Should I get? Placed a 1ohm resistor in the output leg to do a bit of current limiting since the supply is rated at 1000mA. A lower amp charger would work fine, just take a little longer.

Concentration Camps to follow? One test is worth a thousand expert opinions, but one expert specification is worth a thousand tests. Xenomorph posted Feb 22, 2017 at 1:23 PM enable synchronized gimbal pan... Say 14.5- 11.8v = 2.7V drop at 1 amp is 2.7R,, the wattage would be 2.7V *1A= 2.7W,,, say 5Watt rating.

Advanced Search Forum Technical Forums Electrical/Ignition Quick Question About Charging The Battery If this is your first visit, be sure to check out the FAQ by clicking the link above. Most battery manufacturers recommend about 25% of battery capacity (C) for an ideal charger output. It's not even in the circuit becasue the ignition switch is in the OFF position. We assumed the source voltage was a constant 14.5 volts.

Welcome! I had to jump my Cal III last weekend. I just need to use it again. I need someone to confirm this so that the charging process doesn't take longer than it potentially should.

I was going to wire tie the quick connect leads to the frame for easy access. i dont care about prolonging the battery life. No, create an account now. Thanks.

Of course, it's not the only thing that gets plugged in there, it's also the connection for my heated jacket and gloves. For over-voltage protection for the battery, I will attach a crowbar circuit to intentionally blow a fuse located at the boost-buck inputs (the battery will have its own fuse as well). Lead-calcium is absolutely new to me. Let me know if you can't visualize it and I will get a schematic together.

All I want to do is charge it for 10 mins and give it a whirl. #3 Sukhoi, Aug 12, 2008 mooseracing Golden Member Joined: Mar 9, 2006 Messages: 1,712 Thank you. South African's have serious issues facing them. news Sorry, don't know that one.

The other side of the r/r is connected to ground. im afraid to leave the house, i always miss the delivery guy..Click to expand... Actually, I am very appreciative when it comes to online forums when I need help, so me appearing to be rude is your opinion - it's just the way it happened. The battery will let you know if you are using too big of a charger by exploding.

But where does the negative go since there is no car frame to connect to for the dead battery. For example, you have a 100 amp hour deep cycle marine battery that is 50% down, therefore giving you 50 amps to replace. Irreversible changes, like cookie dough before and after the oven... More about the author And current will only flow one way through the R/R, from the alt to the batt, not the other way.

You can estimate recharge time by dividing the amps to be replaced in the battery by the charger amp output.

You would work the resistor value anyway you want but it would go something like this... Some chargers are selectable, and some are gel safe, but this must be determined to avoid battery damage. Now we have 14.5-12.5=2 volts so to get 0.6 amps again we need a new resistor values of: R=2/0.6=3.33 ohms, and the power P is around 1.2 watts so you now
