measuring voltage of a Super Soco battery ?

[paul2129]

I have a Super Soco CPX, I'm keen to measure the voltage at the battery terminals, however theres little to nothing on the battery terminals (plug out of battery obviously) I've come across a wire from a local dealer (which he said was originally used to charge the batteries during transit) I'm hoping to use these batteries to power another project (learning as I go) but I can't even check voltage. On the battery and plug there are terminals as expected and 5 thinner pins, must be communication of sorts, and theres a requirement to do something with these to make the pack allow power to the terminals ? ( or is this simply not possibly since it's negotiated by the bikes computer ? ) I'm not doing very well so far !

any help, most appreciated

I've tried to add a photo of the battery plug, this was described to me as simply a 'charging wire' not something that's normally supplied to the end user, but the plan is to use it for another project.

I know that the thin red/green wires correspond to pins 4 and 5, but that's all I know, and theres not a great deal of readily available info online, other than a few people on Super Soco forum suggesting or claiming to have measured the voltage, that's my first step

Can't you measure the voltage at the xt60 plug? Assuming it uses an xt 60 for discharge.

yep, you can try, and its the same 'almost nothing' that you get at the actual terminals of the battery.

We know the battery is good, was in use today and is half charged. Seems, probably from a safety point of view, the BMS inside the pack has those terminals turned off until it's told (or tricked) into turning them on. A post on a similar, but older connector mentions grounding one particular pin to enable voltage at the terminal.

Why are things I think will be easy.... hard ?

What is plugged into the black socket? You could try seeing if any of the pins have continuity between each other also on the corresponding part check The holes for the pins seeing if any have continuity if there is a pair with continuity . try jumper wire that pair and see if that turns on the output.

thanks for the reply, I know that the pos/neg show little output on the battery terminals, also the same when the wire is connected, I'm frustrated because I'm trying to learn wheat I feel is basic, but I'm struggling. I want power out of a battery, how hard can that be ?

Are there any other connections on the battery? one negative terminal, one positive terminal. What else? and please post pictures of the battery.

Hi, no, literally, the only thing on the battery is the female plug, precisely the connections seen on the plug itself
