I use a 109 for all my lithium packs from 1320 to 8000s. I have it hooked to a 30 amp supply as I don't believe in being cheap and scrimping on the supply capabilities. The supply also runs a 112D charging 16 cell 3600 hydrides at the same time.

Astro109 is a good charger. I prefer Schulze or Orbit myself, but they do cost more becasue they do more. If all you are doing is charging Lipos, then yes, the 109 is hard to beat. The Triton is an inexpensive alternative, but has it limits (5amp charge and 4S cells max). It will charge 4S4Ps, but only at 5 amp,but also does Nicd, NiMh, Lead etc.

The older I get, the better I was

Triton
Actually the Triton is limited to 2.5A when charging lipos, the 5A limit is for nicad and nimh only.

I use the Duratax Ice to charge mine, but it is at its limit 4S @ 8amps. It will also do Nicads and NiMh. If you ever plan to go with more lipo cells than 4, or have no need to charge anything other than lipos, then the astro109 is the way to go.

Take a look at the Orbit Microlader Race.

Ross

http://www.radicalrc.com or http://www.orbitronic.de

Orbit Microlader RACE Non-PC V6.2

Manufacturers Description: If you want to take off with your high-performance battery packs as soon as possible, the Orbit MICROLADER Race is your perfect choice. With charging and discharging currents of up to 8 Amperes, it will make friends with all those who don't want to wait too long to have fun! The convenient program selection provides all you need: automatic quick charging, reflex charging, normal charging, discharging, and forming (or reconditioning) of 1 to 12 NiCd cells as well as NiMh, lead, and Lithium Ion/Tadiran batteries. Operating the Orbit MICROLADER Race is easy: Use the control keys to select the individual operating modes from the main menu. In each mode you can directly enter the desired charging or discharging current or the number of cycles. The LCD display always shows you the battery voltage, battery current, charging time and charged electricity [mAh]. This device is not only a powerful quick charger, but also a maintenance and measuring device for demanding R/C hobbyists. Just like the other chargers of its family, the Orbit MICROLADER Race supports the optional PC interface for measurement data transfer and analysis on a PC with the Orbit MICROLOG software
Comments from Radical RC: This Orbit charger gives you the current capabilities of the Orbit Pro at the price of the Orbit 6.0 with a limit of 12 cells. Primarily focused on the RC car racer or turbo-jet pilot and not suggested for the electric pilot due to 12 cell limit. Orbit makes the Ultimate chargers. Very versital, very user friendly, very smart. If your looking for more than the ordinary, here it is. This charger does all current cells in common use and everything we can think of in the forseable furure.

This version is without PC interface, cable and software.


Price: $243.00

Yes, for an 8000mah pack, 8 amps would be the 1C rate.

1C means 1 times the packs capacity. There are 1000 milliamps in an amp. So 8000ma is equal to 8 amps.

If you were charging smaller capacity packs, like 1200mah, then you would set the charge rate to 1.2 amps.

Basically move the decimal point to the left 3 places.

Remember to get the cell count right too. The number in series is all that matters. Some chargers go by cell count, some go by voltage.

With lipos, each cell is 3.7volts so.....

1S = 3.7v
2S = 7.4v
3S = 11.1v
4S = 14.8v

You get the idea....

So for your 4S4P 8000 mah pack you would set the charger for, 4 cells (or 14.8volts) and 8 amp charge rate.

Twin pack charger????
Hi Amp lovers


I would like to buy a twin pack lipo charger, to be able to charge 2 packs at the time.
The only one I've found is a Hobbico charger:

http://www.hobby-warehouse.com/hoacelchli.html

but it can only charge up to 3S packs and I want to charge 4S packs...

Do I have to buy 2 chargers:

http://h1071118.hobbyshopnow.com/pr...asp?prod=THP425

or is there any charger that can charge two 4S packs at the time??

Thanks

Hutu

Well, the top of the range Schulze isl8-936g will charge 3 packs (one upto 13S, one upto 11S, the last upto 2S) but you pay a lot for the privelidge (just under $899 list price)!

If 4S is all you need, go for 2 cheap chargers like the Apache 2500. Charges 1-4S and upto 2.5A (thats all a Triton can do too!), mine cost $50 last year.
