I was at the field today between 14:00 & 15:00 all on my own , good flying too. There is a dead sheep along the fence line towards the gate from the pits, I saw the farmer so reported this to her. I hope no one had plans for a BBQ Smile .

all my lipo battery charging has been done via a JST connection (may have the wrong letters,its through the Balance plug)

Going to buy a Lipo with no balance plug,now how do you charge them?My charger only has chargring connection via Balance lead. Buy another charger ?

thanks guys in advance

If the LIPO is multi cell I would not buy it without a balance plug.

John is it supposedly new as it's very rare now for multicell lipos to be supplied without balance plugs. When lipos first came to the modelling scene it was the norm to just have the main power leads but for quite sometime now they've had a balance plug of one type or another lipo battery charging Suspect

They can be charged through the output leads which is what we had to do before balancing came along it just seems odd that they should turn up now without said balance leads. Unless the price is very seductive might be best to give them a miss lipo battery charging Fresse

Its actually very rare to find a charger that charges through the balance plugs, as these are severely limited in current carrying capacity. Most units charge through the main leads, and only "bleed" the high cells via the balance plug, during balance phase, using very small currents.

Ive made some enquiries and found that the batteries from this company do have a Balance Lead( not shown on photo) and not given in description.

Thanks for all the very prompt info.

I do have one of them there very rare chargers Tim that just charges up to 2amps through the balance plugs only but my electrikery requirements are mundane by comparison with some of you electro freaks lipo battery charging Icon_wink


John sounds like you're sorted lipo battery charging Icon_cool

Yes Brian,sorted.As a matter of interest my charger also only charges through the Balance Lead.Now for sale ,special price for rare piece of historial electrical rc equipement.

Tim and Co, can you get Chargers that can charge more than one battery a time?

Yes....
if of course the batteries are the same type, then simply make up a parallel lead harness and charge them in parallel....
Rare charger eh? No thanks...think I will pass on that. Very Happy

www.schulze-elektronik-gmbh.de have 2 and 3 pack chargers
All designed by Matthias Schulze and his team
Different system from other makes. Good but Expensive. Specialist stuff.

There are 2 users in RDMFC

Schulze balancers transfer charge from high voltage cells to low voltage cells, not to waste. At a rate of up to 2 amps AND during the charge of all cells.

Other makes of charger/balancers pause the charge to drain all cells to the lowest common voltage cell in the pack....so if the pack was charged it isnt...until it is topped up by more charge ...and so on...and on ....wasting time, energy and flying time.

Why balance? LiPo's get out of balance. Even though you start with a pack that has equal capacity cells. They soon develop different capacities and the smallest go flat and become damaged as they go "under voltage" while the rest of the pack continue being used in operation. The low voltage cells can then be casualties.
Very important to stop before lowest voltage cells are damaged by becoming to far duischarged. Hence the auto cutouts.

Have a look, although german, site has alternative english pages.
Very good direct mail order service and several UK stockists Steve Mettam, Crewe, Cheshire; West London; Revolution Models, Altrincham.

Yep... always found their stuff overpriced TBH and after sales customer service was atrocious the one and only time I ever needed it.
I will NEVER buy Schulze stuff again.

Mmm thought that might happen
I've had exceptional service from Schulze over the years with updates and new gadgets
Well pleased
But I do respect Brian and Tims view

I just thought you might like to hear about my adventures with Schulze John in answer to your original thread

Here is also very nice charging equipment http://www.elprog.com.pl/english/?strona=1_firma&pstrona=02
You can find some info about also on rc groups.
