0.5Amp or 1amp battery charge

[johnnylager]

I have purchased some Sony vtc5 batteries an I have the efest luc s2 battery charger which gives u the option of charging at 0.5amps,1amp or 1.5amp should I be charging my batteries at 1amp? Thankyouplease

Lygte approves of these chargers

It is nice to see a charger that tries a different design and also works fine when charging. With the 3 charge current it supports a wide range of battery sizes and fairly fast charging (The charge current could be optimized, to make it a bit faster). I would have liked a cooler battery when charging at 2A, but for a compact charger without any fan it is difficult to do.
The usb output is fine for 0.5A, but could be better at 1A.

The final verdict must be that it is a good LiIon charger.​

Good to know mate. Cheers. Next lot I'll be sure come from yourself! Prob cheaper than shop too but I was in a hurry lol

No problem mate

If you have any questions feel free to ask

Batteries will get warm when either charging or discharging.

If it's at a slow rate, you'll never notice it as the heat dissipates more quickly than it generates, but charging at higher current will generate a bit of heat.

Charging at a higher rate is pretty similar to hitting it hard on your mods, and will likely degrade the lifespan a little, but if I have to replace a battery a few months earlier than I would have, but I'm charging them twice as quickly for the life they do have, it's a trade off I'll be willing to make.

Everything I've read in this thread seems perfectly fine, most chargers will handle a 1amp charge, some will do a 2 amp fast charge - usually on a reduced number of cells (the Luc V4 will do 2 at 2a or 4 at 1a). As long as you dont exceed the maximum charging rate for the cell then yo'lll do very little to shorten the life span, the rapid charge territory (2+ amps) will degrade the cells life cycle, but most people will only do that once in a while for emergencies - and that will have very little impact on the overall life of the cell...

@Huggett `s delivery is faster and cheaper than going to a shop..Free battery box so youve no chance to torch your trollies, Less stressful, no parking worries, your not tempted to pop in the pub and come out with your back teeth under lager, I could go on but I see a pub..L8TR

I have a question about power supply..

A 120 wire cable has been laid firmly underground between two telephone exchanges located 10km apart.
Unfortunately after the cable was laid it was discovered to be the wrong type, the problem is the individual wires are not labeled. There is no visual way of knowing which wire is which and thus connections at either end is not immediately possible.
You are a trainee technician and your boss has asked you to identify and label the wires at both ends without ripping it all up. You have no transport and only a battery and light bulb to test continuity. You do have tape and pen for labeling the wires.
What is the shortest distance in kilometers you will need to walk to correctly identify and label each wire?

one end label a wire "A". Then join two wire and label them both "B', then tie three (not already joined) wires together and call them each "C"....continue until all the wires are joined together in groups of 1, 2, 3, 4, 5, etc....for a 120 strand cable. NOTES that the largest group will have 15 wires.

Now walk to the other end.

Using a (battery and light bulb) it is now possible, for example, to find the wire that wasn't joined to any of the others. It is similarly possible to find which wires are in a pair, which is joined in a group of 3, etc. Each time a group is found the technician should label it with the letter for the group, so the single wire is labeled 'a', the pair are each labeled "A", etc....this now matches the other end.....the letters will go up to "O". Now take "A", "B", up to "O" and join them together in a group and label each one with "15", so we have cable "A15", "B15', "C15", up to "O15". Take the second and last "B'"wire and
join it with a remaining "C", "D", up to "O" and label these each "14' so we have "B14", "C14", up to "O14". Repeat this until at the end there will be a single "O" cabled labeled "O1".

Now walk to the other end.

Now untie all the old connections and identify the group labeled "1", "2", "3" ..."15" at which point each wire at each end has a unique classification.

2 can play the Google game

I was happily reading this thread absorbing the great knowledge about battery charging and then my head well and truly fell off my shoulders.

Jeeeez.

But yeah my charger only charges at 0.5a so i have no choice, have my eye on the Luc v4 so i can charge at 1a
