Hi Julian
Is there a cheap way for me to make a 12v leisure type battery for my van. I need something that charges up quickly, as I only do short trips & I use the battery to charge phone, tablet, cycle lights, etc…
Ebay OCD! ๐ฏ
hello ๐ How long time i can get curent 1A or 2A for example ๐ 2 hours 5 hours ?
if those resistors are 1 ohm each and in parallel, that's 0.25 ohms per cap. With 2.7v across that we get I=V/R=2.7/0.25=10.8 Amps! That's: Power=I^2 * R = 29.16 Watts…or 29.16/4=7.29W EACH! I have not worked much with SMT but I have felt the untouchable heating of well less than 10W dissipated in a 10W (or even 15W) wirewound resistor. Finally, when all the FETs are on, that's a grand total of 175W of radiated (wasted) heat (power).
Samwah doesn't make 500F edlc
good videos…please keep it going
I do rate the Techno-line charger highly, bought one years ago at a reasonable price and have had no problems ever since [Mines the old 3V BL700 version].
so not sure if anyone has pointed it out or not yet, but eneloop #3 is totally craptastic, it started at 0.89v! and jumped right to 1.41v how much charge did that one take?
I wish all engineers would realize that center positive is the smart way to go. Especially with 12 volt devices designed to operate mobile in motor vehicles. I have a Ham handheld by Standard that has a center negative plug, the car adapter has no real protection, except for the fuse, of course but damn man the inside of a lot of vehicles still have a lot of steel built in, all of which carries the negative side of the power system so that little plug flopping around in the vehicle if you happen to unplug the little radio, and the sparks are really going to fly. Love the little radio except for that problem
SUPER CAPITCORS ARE VERY DANGEROUS .They store a huge amount of energy which if it got shorted by a terrorists could take out an entire block.They should be banned.
Hey Jullian! I'm looking for cheap wire strippers on ebay, and I tought, you may could do a review about those in an upcoming postbag video if you think so. ๐
I can't find any good review videos about them, and on ebay they don't explain, how to use them.
On the other hand, your reviews are really good, and I can trust you.
