Can someone recommend a really good charger that is capable of charging two 6S 5000 mAH lipos concurrently at 2C rate from a car battery?

I also would like all the safety features, ease of use and if possible internal resistance measurements. Good discharge rate (so I can bring fully charged batteries back to storage charge in a reasonable amount of time) also would be nice to have.

Appreciate any suggestions you guys may have.

Thanks.

I'd recommend you take a look at the Revolectrix PowerLab 8. The on-line power calculators will let you see everything possible based on your power supply and packs.

Reaktor 1000 w 30 amp charger.

I second the PowerLab 8 (PL8). http://www.usastore.revolectrix.com/...-EC5-version_2

However since you are to be charging from your automobile you should do some research on the number of charges you can accomplish without damaging the automobile battery. Lead acid batteries do not like deep discharges.

In this case the regenerative discharge feature of the PL8 may prove to be useful. During regenerative discharge the PL8 discharges the LiPo back into the lead acid automobile battery.

The Reaktor 1000w( I Charger 306b) also has regenerative discharge and cost a lot less than a PL8,both are very good chargers.Problem I see is one 12v starter battery is not going to cut it for this kind of power,and if you go 2 deep cycle batts in series 24v or an inverter it's going to cost more than the charger.Several chargers can be recommended to do the job but at this power level your biggest problem is power supply.

Charging two 6S 5000mAh @2C = 504W.

The PL8 will supply that from a 12V source.

Thanks everyone for your suggestions. What do you guys think about:

1. Graupner Polaron Ex (another dual charger with 400W/channel)

2. iCharger 308Duo

3. Hyperion EOS 720i Super Duo Balance Charger

4. Hitec X2 - 400 Dual CHarger

Has anyone used anyone of these (especially for field charging) and how do they compare to PL8?

Archie,

Please provide links when you reference equipment. It saves everyone from having to search and ensures everyone is on the same page.

I have the Polaron EX and the 400W rating is only achievable with 24V or higher input voltage. At 12V it's limited to 220W which means it's capped at 9A per channel for a 6S battery. It's probably close enough to the 2C charge rating that you're looking for. Also since a car battery is usually around 14V you may get the 2C rating.

IMHO, when it comes to performance and reliability there is no comparison. My Dual PowerLab 8x2 goes with me to the field every time I go flying.

Glen,
Thanks. I am working from a mobile device but I will post the links as soon as I get back to my desktop machine.

Has anybody used iCharger 308 Duo in the field off of a 12V car battery?

Buddy RC website says not to but when I talked to the very helpful gentleman at Progressive RC, he said it should not be a problem.

Thanks again for all the help.

Chargepower at 12,2volts is 610watts (at 58A input current). Just the same, as the PL8.

I have the original X-2 dual and love it.
