I required two 3S or 4S 5000mah lipos, anything under 20C is preferred.

Please give me your best price as my budget is RS.1000(negotiable).
As i stated USED lipos would be ok as new ones will cost more. :(

Anyway please do help me as i wanted to use these batteries in the field to recharge my smaller batteries. ;D ;D
Thanks and Regards,
Neil

we have unused new Zippy 4000 mah 3s if you need to buy it.

I dont know if you read my post correctly, but the zippy lipos cost Rs.3000 each. And my budget is Rs.1000 i can do a bit more like Rs.1500 but that is max i can do.

I dont want new batteries as it is not going to be used in any model. Used ones are ok as long as they are working i have no issues.

Thanks Kiran but it isnt what i am looking for.

What  require is 2x5000mah Lipo(Used in working condition)
I will connect both in parallel to get 10000 mah lipo of 12.6v(3S) or 16.8v(4S) Both with 20C or less discharge as in parallel they will become 40C discharge, for chargeing other batteries i dont need 400A of current, 5A is all i need. So even 1C or 5C discharge is more than enough.

OMG, how many people have this misconception :banghead:
I know this is not important for your project but still just to clear the basics...

When you connect 2 LiPos having same Voltage, Capacity (mAh) and C Ratings together in parallel then the C rating doesn't get added.
3S 5000mAh 20C + 3S 5000mAh 20C = 3S 10000mAh 20C and NOT 40C

Theorotically,
20C in 5000mAh 20C means 5000mAh X 20 = 1,00,000 mAh = 100 Amps constant discharge at 11.1 volts
20C in 10000mAh 20C means 10000mAh X 20 = 2,00,000 mAh = 200 Amps constant discharge at 11.1 volts

C ratings does not get added because it is based on the storage capacity of the LiPo. Increase in Storage capacity automatically increases the Discharge Rate but the C rating still remains the same.

Sorry my mistake :banghead:

My calculation somehow came to 400A discharge so i thought its 40C and got confused. :banghead:

I know that only capacity(mah) increases when batteries are connected in parallel and not discharge(C). :P
Thanks for correction bhavesh sir. :hatsoff:
