Can anyone tell me what the difference is between a B-WZKD3615KA and B-WZKD3113KA Santroll control box please I’m still trying to find a replacement for my failed one which is the one ending 13KA
Cheers

No hits for the 13KA one on Google, which is curious.

But according to image below the other is 36V 15A max current, so if the same naming convention applies, yours might be 31V, 13A. In which case if the connectors match the 3615KA would do. But all a bit speculative...

Is there a label?

Are you sure 3113ka is correct, one suspects it is 3613ka.

36= voltage & the 15 /13 is the max current. 3113ka would be strange as there isn't a 31v system.

There is no issue using a 15a in place of a 13a controller, the one Matt has shown is on ebay for £199. Some may say a rip off which may be the case, but they are rare to find as they are OEM only.

Yes here’s the label it’s almost identical

Ok, so it is 3613, not 3113, so the 3615 should be fine. I would hope the manufacturer is sensible enough to keep the connectors all the same!

Thanks I might just get one of those and try, although the number of cables look different on the ones lbw seen
