I have a Pro-Peak Constellation charger, what I need to know is will it charge Li-Po 2s 7.4v 240mah batteries?
It says it will do lipo anyway but I`m not sure it will go that small, any help please as I don`t want to buy another charger if I don`t have to.
Thanks
John
That would depend on the type of cells being used- if they have a charge rating of 0.5C you'd be OK to charge them at 100mA (lowest constellation goes) for just over two hours, you'd almost half the time at 200mA but the cells would have to handle 1C charging, see if you can find any data on them
They are
240mAh Hyperion G3 CX 25C LiPo
Thanks

Up to 5C charging, so whilst you shouldn't fast-charge all the time as it will decrease battery lifespan, you can go up to 1.2A (5 x 240mA) charge rate if you really need to (make sure the charger's set to li-po!)
Many thanks for your help Ewan, I`ll charge them at the lowest it will go just to be sure then.
ok all ready to charge them now but can someone let me know the settings I need to use or at least let me have a pdf of the manual as I can`t find mine now I need it.
finished the ant though!
Go down to charge mode, press set up, the battery type should flash, you press down until you get lipo, press set up again to go to cell number (2), press setup again and select 200ma (only goes down in 100s), and hit set up twice more (I've never changed the last 2 values) and hit enter once it's hooked up to the battery.
Thanks.
Ok set it to C: 0.2A, I`m now getting Li 7.4v 3000mah is that right?
The 3000mA should be reading 200mA
Now charged! :)
I got a battery related. question
will a pro peal supernova. charge lipos
thanks
no
Another charging question!
I have two '7.4v LiPo 4000mAh 40c Hardcase Multi Lead Vapextech' which have output leads and a small balance lead with three pin connector, the supplier told me to charge them through the balance lead but can I do that with just a propeak constellation charger or will I need a balancer too? if so what is recommended?
You can charge them with a pro peak but you need a balancer as well. I've been told something called a Blinky balancer.
I would recommend getting a LiPo specific charger with built in balancer.
We use a Hyperion 1420i but they do lower power models also like the Hyperion EOS 0403i or the Hyperion EOS 0606i
You can use an external balancer with most chargers but it's a bit of a fudge really.
As Kane's said, you can charge with your charger fine, theoretically all you need is a balancer such as the blinky.
I don't really like this system of charging though as the external balancer's are VERY slow at discharging cells to balance them out. The rate of charge normally far exceed's the rate the balancer can discharge.
It will be OK but it's not ideal. I would recommend a charger with built in Lipo balancing. A few people were using the £50 Turnigy charger's that seemed plenty good enough for lower power use.
thanks, have you got a model number for the Turnigy?
the imax B6 seems popular at events, would they be any good

most of the cheap lipo chargers are almost exactly the same and are all pretty good, this includes the imax b6. if you want to splash out more cash heres a better charger:

I use, and can recommend, this charger:

Essentially the same as some of the chargers that have been linked to (i.e. same LCD displays and menus, same four control buttons) but this has a built-in power supply as well as the option to get power from an external source, so you don't always have to lug an external supply or big battery around with you.
Comes with a decent selection of charging connectors as well.
Thanks everyone for all your help.
I`ve been in touch with the Giant Cod site (thanks for the link) and will be going for a GT Power Xdrive Quattro, with the idea of eventually running two feathers it will keep plenty of batteries charged up.
We have 2 of those charger's and they seem to work well. You can find them re-branded under qute a few different names aswell - that one is about the cheapest version of it i've seen though :)
