The red 120 amp connector on the SP140 battery and charger is not compatible with the 120amp Anderson red connector. I searched and could not find where to obtain 2 red 120amp connectors. They have CHENF on the cover. Please let me know where to get these. The below picture shows the Anderson 120 amp on the left and the SP 140 120 amp connector on the right.
The different color Anderson’s are keyed differently. The 120amp “grey” Anderson may fit your connector on the right. The CHENFs are Chinese knockoffs…maybe using a different color is how they get around patent laws on sales to the US…I don’t know.

Hi Bill - I ordered the grey 120amp connectors to check that. I will most likely swap the covers on the battery and charger to the red anderson sb120.
Did they grey ones work with the SP-140s connectors?
I was just blogging about using a universal charger with my SP140 battery (among other gadgets: Finally, the universal charger! – blog.ekus.net ) and was hoping to confirm the name of the new SP140 plug… I believe it’s Anderson SB175 Red, seen here: Amazon.com
My model (received Q4 2021) has the previous black QS8 plug that I then converted to XT90 (and then again to XT60 as these two I use for most of my adapters), link for reference in case it helps others: Amazon.com
Interesting, thanks for posting.
I will have to go back and re-read later in more detail.
I saw the pictures showing charge profiles. Does it have the ability to charge to 80% and stop? What about the ability to lower the charge already in the battery for storage?
I’m assuming since this was designed for e-bikes it is a slower charge rate than the provided charger?
Yes, you can set any target voltage. 100.8V is considered 100%.
For comparison, 86V is about 40%, good for long term storage.
Therefore 80% would be somewhere above 90V.
The charger actually has a predefined profile for 85% or 97.0V, but you can add yours for any voltage.
And yes, the charger can send about 4-5 amps, which is more than my normal ebike chargers, but it’s still much slower than the OpenPPG charger. But again, good for car inverters and slow overnight charging, or from a small power station.
(obviously this 250Wh station will not fill up my 2,200Wh battery, but with 600W limit it would not support the big charger at all)
Hi Bill,
I’m adapting my old 2.2KWh battery towards the V2.5 system.
After a miss buy (Anderson red one), I ordered now a grey one; Thanks for the hint !
But this anderson plug does not have the internal resistor, as the QS8 connector had.
I assume this one was used to limit the inrush current from the 100V battery towards the capacitor bank in the invertor.
Is this not needed anymore in the V2.5 system ? Is this due to the new inverter (which I have), or due to the new battery (in this case, I stil would need to limit this current with my old battery).
Thanks to the community for you feedback !
I hope I’m not too late but the anderson connectors have a warning printed on the back saying “For disconnected use only” and “Not for interrupting current” (see pic). This means that they are only to be connected and disconnected when the battery is off.
The reason these work with the V2.5 battery is because it has an on/off switch. You’ll have to wire up a switch to your old battery’s BMS. I think I’ve seen other people on the forum do it but I’m not sure.
If you connect the anderson connectors together to plug the battery into the ESC while the battery is on, there will be sparks and it will damage the contacts over time.
Thanks a lot for your feedback. Indeed, disconnecting the connector under full load is not a good idea.
According a mouser spec , the connector can support disconnecting under lower currents :
A 120A 600V Anderson SB120 connector is designed for high-current DC applications and, can safely interrupt (hot-plug/disconnect) a load of up to 60 Amps at 120V DC for approximately 250 cycles
So normally, you disconnect the connector when the motor is not spinning, so then the current should be limited.
