How to switch to Lipo technology?

[DuckOfDeth]

that clears that up...'a something'! LOL

Saleens, you have done a great job helping me. I do appreciate it. So what would a start-up cost be to get in this newer technology?
$160 for a charger
$42 for a balancer
Depending on MaH rating, 6s pack gonna run $175-250?

$450 to dive in feet first?
Sound about right?

[saleens7]

yep, thats about it...one you have the balancer and the charger, it will be much less costly to use a lipo setup on other boats as all you need to buy is the batt..

you welcome...

Have you had any safety related problems? Is the charging method similar? How long does it take to charge a pack? Faster? Slower? Do you still need to wait for them to cool down befor recharge, because I see a need for actually getting two 6s, so that I can contiue to run. There goes the wife's birthday gift!!

as long as you are careful, there shouldnt be any saftey problems....the charge time depends on the mah...if you are charging at 5amp (or 5000mah) and you have a 5000mah pack, it will take an hour to charge....i dont know if this is true, i only heard this, so i dont really have anything to back it up...J from JAGS (on the rum runners forum, he's Joreg, from the JAGS team that built the 120mph and 140mph riggers) tested lipo batts and they have less internal resistance when their warmer...dont get them too warm though...ive haerd they are supposed to be cook when they come off the charger...i would wait before they cool to charge...

amazingly, i dont even have a lipo, i just read up on them alot...

That's funny!!!!

You need to get in politics!! Thanks though for your extensive knowledge. I now have the knowledge I need to make the decision and eventual switch over.

Many Thanks,

Duck

I have been running packs in a 4s2p configuration this summer. I have not had any problems with them. I do use an ammo box to charge them in in case anything happens. The majority of the problems I have a read are when people misuse them. You do not want to go over the recommended charging current, if the packs get damaged they should be discarded and if they only hold 30% capacity it is time to discard them. You also need to use a charger that is made to charge LiPos!!

My 4000 mah packs take about an hour to charge.

I'll need to invest in a better charger, as mine will now only go up to 4s. So two packs it will be, a new charger, and balancer. $650.
The kid can go hungery for a while, new batteries...must have!!!

i have a little lipo question of my own now...

if i had a 2s2p pack (like this one http://www.maxamps.com/proddetail.ph...o-6000-74-Pack) if i had two of these 2s2p packs, would the charger just recognize them as a 4s pack? or as a total of 8 cells to be an 8s pack? just thinking of battery ideas for the SV27.

[NorthernBoater]

If you were charging two 2s2p packs in series you would need to tell the charger that you have hooked up a 4s pack.

[saleens7]

ok, just making sure....my charger has a 5s lipo limit and i was thinking of using two 2s2p lipos for the supervee...

i finally figured out what the mysterious 'C' rating is

(coming from my triton 2 manual):

Capacity is also referredto as the "C" rating. Some battery suppliers recommend charge and discharge currents based on the battery's "C" rating. A battery's 1C current is the some number as the battery's rated capacity #, but noted in mA or amps. A 600mAh has a 1C current of 600mAh (or 0.6 amps), and a 3C current value of (3x 600mAh) 1800mAh or 1.8A. The 1C current value for a 3200mAh battery would be 3200mah, or 3.2amps...
