where is your charger for the LI-Po's ?

[j.p.75]

I must buy TWO chargers for my RAZOR AKKU'S...

Where is the best charger...:?::?: :dontknow

Thanks for the answers...

TP 1010 will charge 2 5s batt's. Coupled with the TP 210 balancer, It is a fool proof setup. I got my power supply from radio shack, but now, many online vendors can beat their price.

Now, If you're going to run 12s, then I don't know what to tell ya....good luck! .. :D

[buster1]

so, one 1010 can charge 2 5S batteries at one time - so, two chargers, could 4 at one time - is that correct?
Thanks,
Jeff

Yes...

The 1010 can charge up to 10 cells. It does not have connections to charge two seperate packs at a time.

You could charge two packs prewired in series but, I don't think you can plug two 5s packs into a 210 balancer at once.

You may wish to contact Thunder Power to get a clearification on this.

I am going to use two 1010s and two 205 balancers to charge my Razor setup. This will give me the best charging performace I can get. I would not try to charge a 10s setup with one 1010.

Why not, isn't that what the 1010+210 combo is meant to do ?

You can charge 2 5s packs withthe 1010/210V at the same time using the 210V. All you need to make up is a series cable. You have to be careful which pack is bank A and bank B but a lot of us are using this setup. Most amps you can charge with this setup is about 5 and it will suck your car battery dry in a few charges. We use a generator and power supplies.

The other thing to watch out for is that as your input voltage starts dropping with the 1010/210V setup, your packs will false peak and not be fully charged. Firmware updates have helped but the 1010/210V is far more prone to this than my Schulze chargers. Charging in series aggravates this condition due to the high voltage IMHO.

So basically, use a Power Supply to charge your packs in series works a LOT better than a car battery.

Why could you not parallel charge them as a 5S double the Mah battery. My Astro chargers(4) have a greater discrepancy between them than any of my series packs do when tested seperately. If the Packs used in series, as on the ION, when seperated if they are within .10V why not charge them togther with a parellel connection?

Just curious, I have been charging a pair of 4S 2000Mah as a 4S 4000Mah for a couple of years with no problems...

Doing it this way would also keep the pair of batteries balanced over all to the same Voltage..

I have 4 Astro 109's and each one is at least .20V differnt from each other . I have mated the pair that are the closest and that is the arrangement I use for my ION packs..

Never charged in Parallel, how would you use the 210V balancer with the 1010 in parallel? I don't think that can be done.

We have found through a LOT of testing that you want to charge/balance pairs of packs for a machine that takes 2 in series to get the absolute closest balance and best performance out of them.

[jrohland]

I plan to get pairs of 5s ~4600MAH packs. With a TP-205 attached to each pack, I want charge them a 3C (at the field only, at home 1C). That would require 13.8 (4.6x3) amps. Since I will be using a TP-1010C charger, I will get 10 amps max. With two 1010s I can charge both 5s packs at about 10 amps simultaneously. Big surprise, I will be able to charge two times faster than one 1010c and a TP-210.

I plan to use the two accessory (cigarette lighter) outlets of my Toyota Prius and leave it started while at the field. Each accessory outlet is fused at 15 amps. The 1010 pushing 10 amps at 18.5 volts should require about 13 amps from the outlet. In theory it all works out.

For those of you who don't know, the Prius is a Hybrid auto. As such, it will start and stop the motor as needed to keep the large battery pack charged. This is--in effect--a smart generator which runs only when needed.

I have a couple questions.

Will the Prius deliver 10A out of both lighter plugs are the same time. Last I heard a lighter plug is only good for a few amps. Be careful and don't burn out your wiring harness in the car.

Will the 1010 really charge at 10A with a pair of 5s packs in parallel? Not sure never tried, but maybe not. Let us know how it goes. I have a 205 you can have to add to your mix if you want. PM me your address and it is yours.

Be careful and don't burn out your wiring harness in the car.Since the advent of tail gate parties, vehicle accessory outlets have pretty high current ratings. The Prius has two outlets, independently fused at 15 amps per outlet. It should be possible to pull 30 amps safely.

Will the 1010 really charge at 10A with a pair of 5s packs in parallel? Not sure never tried, but maybe not. Let us know how it goes.I'm not sure but, I have charged 6 cell packs at 8.25 amps. It should be able to charge 5 cells at or, near 10 amps.

Remember, when charging at voltages above the input voltage (12 volts), the 1010 needs to step up the output voltage. It does this by pulling more amps from the input source. That is why charging a 5 cell pack at 10 amps requires about 13 amps from the source.

I have a 205 you can have to add to your mix if you want. PM me your address and it is yours.Thank you but, I have all the 205s I need. Perhaps someone else will want it.
