[Tosk]

hi all, i need help setting my B6 charger up please

im using

2x Turnigy nano-tech 850mah 2S 25~40C Lipo Pack =3 Cell / 11.1V
2x Turnigy nano-tech 850mah 3S 25~40C Lipo Pack =2 Cell / 7.4V

what i need to know is what setting should i be using please?

i know the voltages thats an easy 1 lol and the cell count, but do i need
to set any think else?

thanks

I think you've got those the other way round, but it doesn't matter.

The only other thing you need to set is the charge mode - I'd advise using the LiPo "BALANCE" mode but it's up to you. Some B6 clones let you charge entirely through the balance leads, but others require both the balancer and the main power leads to be connected. I'm sure you'll work that out.

hi QuackingPlums, ok thanks

yea ive read abit more on charging now, and like you said its best to charge using balance mode.

what about the amps how would i go about it? is it the more you add the faster it charges? but the
more you kill the life span of the batterys?

what would you use for the 850mah 2c & 3c please? i was thinking 2.0 to 2.2 maybe?
would be nice if there was a guide that would help ppl.

thanks

hmm ive just been looking on the net, and ppl are saying you divide the mah with 1000.
then times it by the cell.

so 2c 850mah * 1000 = 1.6a & 3c 850mah = 2.4a

is that a good way to go about it?

or is that wrong? any help would be greatfull

thanks

I would charge at 1C, which for those packs would be 0.85A (nearest the charger will do is probably 0.8 or 0.9).

Never heard of multiplying by the number of cells before but you can't go wrong with 1C. Even with packs rated for higher charge rates you will reduce the lifespan of the pack. If this is not an issue then you can go up to whatever the pack is rated for - usually 2 or 3C.

hi again QuackingPlums, ok thanks m8

i will charge them around 1amps then, as i dont really want to keep buying batterys, if they last
me 1 year i would be very happy

thanks again

More importantly, don't run the batteries flat. Keep them above 15-20% or 3V per cell. Store them at 50% if you're not using them for a while!

All good advice there by QP

Some good REP would nice

[giskard]

Yep agreed! I only ever charge even better cells at 1c and cell count has nothing to do with it.

cool thanks QuackingPlums

yep i gave him some good rep on my reply befor

would buying a little Battery Monitor be a good thing to keep on me when out flying?
