EGO lawn equip battery - can’t easily measure voltage

[harrymanimus]

Started to post on a lawn forum, but people here might be more apt to know about this.

EGO 56v lawn care system lithiom ion battery, trying to easily measure voltage as I have 4 batteries with no guage on them. I bought this off ebay for *ease*. More below:

Battery adapter for EGO 56V 12AWG gauge 2ft lithium output dock power connector | eBay

Wire: 12AWG. Disconnect the battery before the battery reaches 14 volts (to extend the battery life). This battery adapter has been tested and can be used with EGO. This battery adapter has been tested and can be used with Ryobi Ryobi One.

www.ebay.com

What does NOT work:
Volt meter prongs are too big to reach the +/- metal in the slots on Ego battery.
Shove a paper clip into the + on Ego, shove another paper clip into the - on Ego, read with volt meter. Nothing
Connect ebay connector the correct way and check voltage on output wires. Nothing

What works: Lay the ebay connector ON TOP of the Ego slots so the metal is resting on top of the the +/- of the ego battery leads (not slotted in properly), touch volt meter leads to exposed metal ebay connector. Get a correct reading.

What am I missing here do you think? Of course one thing, the connector I bought could be bad.

Thanks

I figured it out. Opened up the connector, a wire was loose. Able to measure now.
