I have 3.7V 4000mAh Li-ion cellsI need to connect them in a way to create a battery pack to run a motor of 6000W 60V.I know in need to connect 16 in series to get 60VBut by how much in parallel?Thanks
If they are 4,000 miliamps, that's 4 amp. You said you need 6,000 watts? That's a lot of juice and money my friend. 60 volts x 25 4 amp batteries would equal the 6000 watt load you need. 25 batteries in parallel, already stacked 16 In a row in series. There are much much better alternatives and cheaper ways of doing this. But if you do decide to, you'll need to know how to run series parallel circuits and keep the wiring even along all batteries with lowest resistance wiring as well to work.
How is the battery pack connected in series?
Can be the first string into the same battery, and then parallel. Such as: 1.5 volts battery 9, can be a group of three in series, into 4.5 volts, then the three groups in parallel, each group of positive phase, negative phase. The total voltage of 4.5 volts, the capacity of a battery 3 times.
cuz i got an electric snowblower. i know. it sucks! it mostly sucks because i gotta deal with a cord in the winter. it gets very hard to deal with. do they make battery packs that i can plug into it and then eliminate a cord? or is there something like that but instead of batteries, it sends a signal to a receptor plugged into the wall, eliminating the cord??thanks
You've just learned why it is not a great idea to have an electric snow shovel. That power cord is a dang nuisance! The answer to your question is not quite no. There ARE rechargeable battery devices that will supply 110VAC to operate your snow shovel; but they are heavy and not intended to be carried around. They are for emergency use of 110 VAC appliances where there is no available AC outlet. You can find them in Auto Supply stores and truck stops. They typically have both heavy-duty battery clips to connect to a car battery, as well as a standard AC power cord. This way the batteries can be charged up on the road or in a dwelling. The batteries themselves are small versions of car batteries; and as you know, they are not light. Add in the transformer to up-convert the voltage, and you've got a rather heavy device to lug around. As you might guess, this is an impractical way to operate your electric snow shovel.
I have an HP laptop and I can charge it to 100% battery and within 15 minutes the battery is dead. Do you think it's something I'm doing or is it the laptop?
How long have you had the laptop for? If it's more than a year it's likely that the battery life is at it's end. Has the decrease in battery life been gradual or did it just suddenly stop holding its charge? If it's new, it very well could be a defective battery. HP did just have a voluntary recall on certain batteries. Check their website for information on it.
I want to find an external ipod battery pack that works with the ipod nano 3rd gen. and doesn't add on a lot of bulk. The best battery pack I've found so far is the Tekkeon mypower battery pack, but I'm not sure whether it works with ipod nanos. If you find out please tell me. If you find any other good battery packs that are nano compatible please tell me.thanks
try OKorder they have a lot of selection and good prices!!
I have the newest type of controller and Xbox 360 (the slim). Just today it randomly disconnected, thinking it was the battery, I ran to my room to get the play and charge charger, not noticing the fact that it didn't turn off, but it disconnected (it turns off if the battery is low) as if it wasn't synced to my Xbox. It is a hassle to get it to sync with my Xbox, and even still, if I move it too much, it disconnects again (NOT turn off, it isn't the battery life!). How do I make it not loose???
Just be ghetto and tape it or buy a new one
i have a psp with a standard 1800 Mah battery but was going to buy a 2200 battery but don't know if that is a worse battery than what I own could somebody tell me and also tell me which is the best.
yes,you okorder
Electric car battery pack is 12V good or with 16V?
If directly from the price point of view, 12V more advantages.
