First lipo charge. I just wanted to check things out before its too late.

Charger EOS 0720i NET3 AD (ac/dc input) 10.5V~29V DC (20A, 150W max charge) 100V~240V AC (20A, 90W max charge)ze.

Lipos Turnigy 5000mAh 2S 40C Lipo Pack apacity(mAh) 5000 Config(s) 2 Discharge(c) 40 Weight(g) 308 Max Charge Rate (C) 4

Parallel charging board ParaBoard-XH T-plug New 30A version larger 12 gauge input silicone wires 4mm bullet input connectors 30A safe PCB fire retardent plastic case evenly separated power plugs pairs EC3, XT60, and T-plugs available

Math I want to parallel charge 2s 5000 lipos I will charge at 1C=5amps with the option of 2C=10amps

I will set up the charger to 4s 5000 @ 1c and use the charging board

charging time assuming a 1C charge rate is set 2s 5000mah lipo = 42watts / 90watt charger = 0.46 hours for a full charge- about 27 minutes. 4s 5000mah lipo = 84watts/ 90watt charger = .93 hours- about an hour

give or take 10 minutes for balance.

I might have my watts screwed up. Im trying to figure that out right now. Am I figuring this wrong. I didnt buy the stuff yet I just want to be right.

Hi Geeves.
Glad you asked the question.
When parallel charging 2 x 2s packs, DO NOT set the charger for 4s. Set it for 2s. You are still charging a 2s pack when they are in parallel. Commonly referred to 2s2p.
Also, to charge each pack at 1C (5 amps) you will need to set the charge rate to 2c (10 amps.) Each pack in parallel will receive half of that, at 5 amps (1c).
Trying to calculate the charge times & wattage etc is a bit hard as the packs will come to you in roughly a half charged state. The readouts on your charger will give you the info at the end of the charge.
Bear in mind that the total milliamps number on the readout is for both packs. Each pack received half of that number.
All the best.
Paul.
