IMAX b6 power supply

Just purchased this before realising they offer an mains version...

just looking for some links to adapters to use with this charger so I can plug it into the wall?

 

plenty on the search but a lot of out of date links and advice. Some people say a connector needs to be soldered on, is this correct?

 

many thanks

I believe most people use a laptop charging lead  for this as it delivers the required voltage (between 11-18V).

OLD LAPTOP PSU

 

input voltage is 11v ~ 18v req about 3amp min to say 5amp

 

5.5mm plug with 2.5mm center I think (positive center is the usual norm)

(most modern plugs have positive center/pins but please check polarity ffs)

 

Now you "might" be OK with a little over the 18v limit as voltage regulators usually work up to 34v or something

BUT DON'T BE F*CKING STUPID, 19v laptop PSU's "should" be OK - well you get voltage spikes etc.....

 

You need about 3amp to charge say 2000mah/2amp lipo's quickly

the B6 charges much faster than the trickle slow B3 chargers

B6 charges through deans say and balance through the JST or balance connector thingy

B3's charge and balance through balance lead only - so thinner wires takes longer

(but handy coz it don't matter if deans/tamiya/XT60 LiPo's - don't need adapter to charge on B3)

 

Most laptop PSU's will be of the right spec volts/amps - just if they got the correct plug on it

I know one particular IBM/Lenovo psu works great but they changing stuff often

In the end I bought a "Universal Laptop PSU" - a psu you can select voltages and have different plugs

(to suit or work with most laptops), found a plug that fitted, (check polarity (test meter) set 16v & sorted)

 

You might already have an old laptop PSU lying around the house

you might get lucky and the plug might work correctly - but unlikely as so many types

 

I got a clone which came with loads of leads inc a 5.5mm plug on crocodile clips or something

so if there is something like that in your box supplied then you can splice that on the end of PSU

 

you want the inner/center of the plug/socket positive polarity like LEFT PICTURE....

 

 

IF YOU DO NOT UNDERSTAND THIS THEN DO NOT ATTEMPT STUFF !!!!

 

Seek some help from an electrical m8 if you are unsure - just trying to help you get by

 

Or buy a PSU designed for the iMax B6

 

Also being 11~18v means you can take and charge in the car on way to game via cigarette lighter plug

 

No worries if you haven't got an old laptop psu - just buy a B6 psu

 

Old modems/routers psu of say 12v 1amp usually have smaller plugs than B6

but often these plug/psu units used on old modem/routers are ideal for cheapo B3 chargers....

 

 

F*CK ME, Sitting Duck's airsoft money saving tips

 

Martin Lewis eat ya heart out

 

Seriously, you can often find you don't need to keep buying stuff or new stuff sometimes

some stuff just works fine or costs very little eg: ptfe tape and wotnot

 

FAILING THAT....

There are loads of ads for psu's - just watch out for Hong Kong sellers claiming item is shipped from UK

Often if they say it ships from UK it will likely arrive in a few days like they say

BUT some sneaky bastids appear to be UK sellers and claim it will ship from UK

but it ships from China and may not arrive for 3 weeks or so

 

So if you have an old psu to hand and some luck or electrical common sense you should be OK maybe

Don't buy random laptop power supplies.

 

I highly recommend that you use a 12V 5A rated power supply like this one I bought a while ago: https://www.amazon.co.uk/gp/product/B01NAHGRAQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 

 

You may find cheaper than the one I linked which is fine but I got mine safe and sound from there.

I was thinking this from eBay (don’t use amazon)

Any good?

[Sitting Duck]

That will do

 

reason why a laptop psu is often used, well decent brands hopefully use decent psu's

rather than a oem brand x one & - well old psu from dead laptop is nigh on free & to hand

 

voltage input is 11v~18v but this amount is stepped down charging LiPo's at up to 4.2v

(even 11.1v LiPo's)

 

The input voltage HAS to be a bit over the output voltage or if input is near output voltage

well the output voltage starts to drop. eg: common 5v 7805 voltage regulator

 

9v into a 5v volt reg = 5v output

6v into a 5v volt reg = 4.5v output say

 

the max input for a 5v 7805 is 24 - 34v depending on spec/model/manufacturer

so on that basis if the psu you had to hand was say 19v it should be ok I think

but it don't matter coz you are likely to buy one from ebay anyway

Just purchased the eBay one I linked

 

 many thanks sitting duck and others for the speedy advice
