Charging 4 batteries at once....

[ScarabChris]

Can I charge four 5000 mAh 6S batteries at once?

And if so, can I do it with my Thunder AC6 charger?

It just takes so long to charge them individually. At nearly 2 hours per battery you're talking a whole day to charge them.

To charge those 4 batteries in parallel at 1C (20A total) you need a charger capable of outputting 500W, plus a power supply that can supply enough juice for that (600W min).

Check this for a nice calculator:

Your charger has a max charging rate of 5A and 6S, you could charge all your batteries in parallel, but it would take approximately 4 times as much as the single battery, plus when charging in parallel you can't use the balancer and check if the cells get charged properly.

If your batteries have a charge rate of more than 1C you could charge each at 2C (10A) for a charge time of about 40 minutes, add another charger to the mix and you can have all 4 charged in less than 2 hours.

Looks like your charger can only output 5A so if you want to reduce charge time you're going to need a better charger and power supply.

Yeah its only a 5 amp charger. Damn I guess I need to drop some coin if I want to get two runs in the same day.

The question is a good charger cheaper than just buying 4 more batteries?

I have 2 ECO 6-10 from HK, they are 200W and can charge a 6S up to 8A.

The Hyperion are great chargers too, buy 2 of these and you can charge your 4 packs at the same time (12S per charger).

You will still need a power supply (or 2) that can provide enough juice...

I have an Icharger 208 that works great for charging up to 20A and I just upgraded it to a Cellpro Powerlab 8 that charges up to 40A. Again you will need a good power supply. I use a converted server power supply that outputs 12v 74a on 110 ac that I bought for $40 or so.

Looks like the price went up on them to $55 https://www.serversupply.com/product...arch/query.asp and here's how to convert if you're interested http://www.rcgroups.com/forums/showt...0#post11639297

That link didn't work, try www.serversupply.com and search for 406421-001. It's $40.

[GP73]

WOW, 1300W power supply for $40.

That's nuts! Good find.

To be wise just invest in a good charger instead of more packs. Charger lasts very long while lipos will age even not in use. So just charge/discharge your exsisting packs as many as you can before they get old.

Well, you could buy 3 more AC6s for $42.70 per ......... lol ...
