8S charger… this might make it a bit easier to charge up everything… will try to look up that 8s wire harness
This is the cheapest you can get it I think! Also im not sure can you get these in Eu… at least I didnt see them on hobbyking… + 8s seems not be a popular choice, so it is hard to find much for 8s
You combine the previous cable with this one:
You would need to cut down the ‘‘male’’ connector and solder the wires to the 8s connector…
This way you should be able to plug your 2X 4S batteries into 1x 8S cable (when soldered together!)
EDIT: You can also buy 4 of these cables and then just wire/solder them to one 8s cable…
Otherwise, just get / buy cable like this:
Unfortunately, I could not find one from china! This is from usa… When going with multiple battery packs connected, the bad part is the wiring…
You will also need to adjust the lenght of cables (make them longer, for example) to make it comfortable to reach the balance charger from your battery/board!
You will need to know how to solder! It is not that hard to solder these small wires (just hold them down steady)… but you will need to know how to wire them up correctly!
I also would advise to buy silicon balance leads, they will be a lot better than these tiny/cheap ones. (the ones shown, should be silicon wire already but im not sure will you order the same items at the end!)
Found an alternative, looks like some UK vendors also have these cables in stock:
Look it up, for some of the cables, the quality might not be the same. but the one I gave you here, looks quite ok!
You would also need to cut into the cable to make the parallel connections…
To join 2x 8s batteries, you will need to make a parallel connection… Unless you charge them seperately / one by one… which wont be fun I think…
This is all I could give… the rest is up to you…
Text diagram, to make it easier for you:
2x 4s batteries goes into 1x 8s battery cable, then 2x 8s battery cables goes into one 1x 8s battery cable, which is connected to the charger.
|Battery| Male connector -> Female connector (4s) > Bare wires (5pcs) -> Bare wires (5pcs) -> Bare wires (9pcs) -> Male connector | 1x 8s connector|
1x 8s connector (Male) + 1x 8s connector (Male) -> 1x 8s Female connector (per each) -> Wires -> 1s 8s Male connector
Good site to compare / take a look at balance wires:
If there was a ‘‘ready made’’ cable for 4s x 4 to 8s x1, then it would be pure gold in your situation…
Perhaps it is possible for you to make it a ‘‘direct cable’’ but it is up to you how do you see it easier…
So yeah, you can actually buy 4s x 4 female cables with wires, then solder all of them to one 8s 1x cable… IT will look something like this:
