Default Recommendation for 4x 6s Lipo Charger Under $250

I currently have two of the Traxxas Dual EZ Chargers Up to 3s. I would like to have a 4ch charger that can do 6s. I would like to be around $250.

I was considering the following chargers
Dynamite C2050 Prophet Sport Quad 4 X 100W -6s $200
EV-PEAK CQ3 100Wx4 -6s $200

Currently I have
4x Traxxas 3s 25c 5500mAh
2x FLOUREON 3S 35C 5500mAh
2x Lectron 2s 5200mAh


My Vehicles
Yeti XL RTR 2s/3s
Slash HCG 4x4 Castle ECS MAMBA MONSTER X EXTREME 2650kv 3s (Maybe 4s)
Slash LCG 4x4 Castle ECS MAMBA MONSTER X EXTREME 2650kv (Maybe 4s)
Jeep Rubicon SCX10 Castle ECS MAMBA MONSTER X EXTREME 2650kv 3s
***Looking to buy soon E-Revo Brushless 2s/3s

If planning on charging 6S packs at a 1C charge rate, you will want a more powerful charger.

Could you suggest something? In the near future I have no need over 4s. I was just trying to plan ahead.

I personally use the Graupner Ultra Duo Plus 80 charger (about a $200 charger), it only has 2 output channels, but I can charge 4 5000-7000ma 6s Lipos at once. 2 6s Lipos in parallel on each 500W charge channel (20A per channel @ 24V).

If you really want to charge 6s batteries, I highly recommend getting a charger that will run on a 24V source. Charging 6s packs on 12V is painfully sloooow. You will also need a 24V power supply, or 2 good Pb batteries wired in series. I personally use a 2200 watt quiet generator and about a 50 Amp 24V power supply, I went with this because I was highly annoyed by taking 2 hours to charge a 6s 5000 Lipo on a 12V supply.

My previous Hyperion charger was decent until I started playing with 6s packs, the charger would only work on a max input voltage of about 14 volts, but it would charge a 6s Lipo, this cuts the charge wattage in half right out of the gate.

Thanks for the recommendation. After looking at my current needs and future I may have have been over zealous on the need for 6s. When I thought about it. I either run dual 2s=4s or 3s=6s. I would like to have the ability to charge at least 2x Gens Ace 4S 5000mAh packs in 30-40mins. They have a claimed 5c Charge rate. I honestly am not sure how fast that translates to but it would seem to meet my needs.


I look at the.....
Graupner Ultra Duo Plus 80 charger (1000w) (Suggested)
Icharger 308DUO (1300w)

Both are nice chargers. Capable of doing more than I need. I have a 24v 750w 31.3a Mean Well Power Supply Very Noisy! That should be enough power for either right?

this charger would work well with your power supply and be cheaper then the Icharger

Should have mentioned that before.

The Turnigy Reaktor would fit the bill nicely...for a dual charger. You just have to check the specs on anything to make sure you can live with it. The Reaktor has a limit of 20 amps/channel. That's still plenty of power for a lot people. You have to also consider the longevity of your batteries when you charge at a higher rate. I'm happy waiting approximately an hour for my packs to be done when charging my batteries at 1C rate, and in doing so I give them a longer lifespan. Once in a while I will use a higher charging rate, but rarely will I go over 2C.

Charging at a 2C rate will get you within the charging timeframe you want.

You say the Gens ace batteries are rated for 5C charge rate...
Charging a 5000mAh pack @1C rate = setting a charger at 5 amps.
Charging a 5000mAh pack @2C rate = setting a charger at 10 amps.
Charging a 5000mAh pack @3C rate = setting a charger at 15 amps.
Charging a 5000mAh pack @4C rate = setting a charger at 20 amps.
Charging a 5000mAh pack @5C rate = setting a charger at 25 amps.

Charging a 4S LiPo pack, at a 4C charge rate (16.8 volts x 20 amps = 336 watts), would be going beyond the Reaktor's maximum charge power capacity of 300 watts. The maximum charging current, using the Reaktor, would be around 17.8 amps and charging time would be approximately 15 ~ 20 minutes.

A little more money but again you get what you pay for. I run two 6000 6S packs in series for my RC airplanes and use a powerlab 8 and parallel board with two 12 volt 47 amp server power supplies in series off a generator. Two deep cycle batteries will not cut it for long charging at the higher rates your looking at.
