This charger is not meant for permanent installation so it only comes with Croc clips on. This is not always ideal having to get to the battery terminals especially when opposite corners of a 500ah bank.
I fitted Anderson connectors to both my battery sets for easy connection of a high power air compressor so I decided these will do for the battery charger too.

Charger lead modified for both options £5.99

CTEK have their Comfort Connect range of connectors to do a similar thing. Most of their chargers are now supplied with the Comfort connector ready installed in the output lead & at least one termination set - usually the croc clips. I think mine came with the croc clips & the M6 eyelet set.

No good in your case, because you had the Anderson connectors there already, but very useful for those who want to use the charger to charge batteries in-situ in several vehicles - or just have a more secure but easy connection.

Not the MXS 25 there is no such connector

Basically the MXS 25 is made for use at a workstation and the battery is brought to it for conditioning. A bench situation. There are no other connection options other than as supplied with crocs and temp sensor

Local temperature sensor Jim and not featured on the lesser CTEK chargers that @TheCaller alluded to
Which explains why no Comfort connector for that model. Do you use the temperature sensor or have you ditched it as part of the convenience of the Anderson connector?

Yes I will use it. The connector is in the same compartment with both battery sets
Connector being just out of shot on the right

The comfort connector cables are most likely of insufficient CSA too. This unit uses 10AWG

This is my charger in use with the CBE one turned off.
I simply unplug it and move it to the garage to charge the other battery bank

@Techno I need to understand what you are doing here as I want to build a setup where I can be off hookup for a longer periods. I know you're the champion of this electrickery lark and trust your judgement on how to do this. So...

You appear to have 4 batteries in one location and 2 in another?
Are they all wired together giving you 600(ish) ah?
Are they all fed by a solar array and single soar charge controller?
I know you have a sizeable inverter (or two) do you run this from the larger bank?
Is the Rapido factory fit charger and power supply still in use?

Tell me do :)

8 125ah batteries in two banks of four
Bank one does 12 volts only and is charged by b2b CTEK charger and any surplus solar
Bank two does 230 volts only and supported by 300 watt solar and CTEK charger
Banks can be combined if it suits
If the batteries are not much depleted I leave the CBE chargers on which are 16 amp. If they've had a hard time I use the CTEK charger 25 amp instead
