I have this charger. It is decent upto about 2A charge rates. After that it struggles to balance the cells and charge times begin to become extremely long and unpredictable because it can't balance and terminate.

That said, you can charge a single Gens Ace 2S 450 @2.2 amps (5C) and it will finish the pack in 10-12 minutes.

For my larger packs and higher charge rates, I have a Power Lab 6 running on 24v. Awesome setup! The only thing better IMHO is a Power Lab 8.

Geez, you guys charge fast, I've always charged my packs at .5C, maybe I'm missing something but I thought slow charge rate equals longer battery life. I hate buying batteries, I want to maximize the life of the ones I have.

I have the parallel board but dont remember where I got it. Ebay I think. I'll look through my stuff and see where it came from. Maybe it from progressive rc.

Lol! So you charge for two hours? you can easily charge most packs these days at 2C, if not 3 with barely any damage. You are just wasting precious flying time!

Hey JC - Do you know what is the maximum amps you can charge the Gens Ace 2S 450's at with a Thunder Power 610C charger and still balance them?

Also...how is charging at 5C on the batteries? Is that hammering on them pretty hard? Wondering how much it would decrease the life expectancy of the pack compared to say charging at 4C, 3C, 2C or 1C...

How about for 3S?

EDIT...Oops! Didn't mean the Gens Ace batteries, meant the Twisted Hobbys batteries. $9 for 2S each...

All this talk about charging has me wondering...I use the Gforce Lipos from valuehobby in my Xtra slick. A bit more $ than the gens ace, but usually in stock. Anyway, I have been charging them (2s 500mah, 20C) at .5amps, and it takes about 2 hours to charge them. Is it safe to charge these packs at a higher rate? I think my charger can output 2amps, and if the batteries will take it, I am all for quick charging.

Thanks
CG

I don't know much about those batteries but charging at 2 amps is like 4.5C. If they can take a 5C charge then do it!

If your battery doesn't state the charge rate then 1c is usually the safest bet.

Ok. Now the problem is this...my charger only lists charge rate in amps, not C. If someone could share the formula for calculating amps to C, and C to amps, that would be great.

Thanks guys. I am learning something today.
