Apologies if this has already been asked.

I have a ECM2900 + ECS2900 battery currently, but I'm looking to gradually increase the capacity. I understand the EQ range is basically an upgraded, newer product over the EC line.

So my question is please: can I add an EQS2900 battery on my existing ECS stack?

Many thanks
(Type A, Version 2)

The EQ2900 is a type A connector and so if your battery is also type A, yes they are compatible and warranty will not be void.

If you speak to the community recommended suppliers they will confirm compatibility for you (and hopefully give you a discount) https://foxesscommunity.com/viewtopic.php?t=531
