Wrong Model ZKETECK EBC40L. I just received my long awaited tester from China and it arrived with the wrong power cord (plug) and the plug says 230v, 10amp. Does anyone know what power may be acceptable, i.e. 120v, 60hz? In other works do I just need a proper plug or is there a different power supply in the tester for North America?
Its the EBC-A40L. Not the EBC40L not the ECB
EBC-A40L
Interesting to me that the inside of it contains a 60A power supply yet the charge is limited to 40A (manual says 35A but that might be the prefer derated current)? I own the EBC-A20 (kind of wish I had gone with the EBD-A20H)
EBC means the charger has an onboard charger OR in the case of the the EBC-B20H it allows an external charger to be connected.
EBD means it is a discharge only unit.
I'm not quite sure what to make of the letters used but I do know that the number is usually indicative of the current rating for discharge but keep in mind there is also a watt limit. The EBC-A20 has an 85W limit whereas the EBD-A20H has a 200W limit but it does mention running it at no more than 90% of its wattage rating so 180W. The EBC-A40L has a 40A discharge current with a 40A charge current but like I said the manual does says 35A.
There are now a couple other options available
50A charge and discharge

There's also a big brother version to one of the above testers for doing more than a single cell. There's also a 4 channel version that allows you to test 4 cells at once, its literally nothing more than 4 of the devices in one long shell
Then there's the newest electronic load from Atorch the DL24MP which is modular and with 3 extra modules (boards that contain 4 mosfets, some power resistors, anemic heatsinks and a fan) it is supposedly rated for 600W and 40A. I, along with others, have found that hitting 40A is just flat out impossible. Mine cuts off at 34A....33A its fine but the second I try to nudge it up to 34A the discharge current just stops yet the device still shows it is "ON". Atorch had the nerve to tell me my battery did not support 40A discharge....its a 12V chunk of one of the 36V/40V electric bus batteries with A123 26650 M1B cells. I don't believe my battery was every installed in a bus, all the cells measure 5.8mΩ AC IR and capacity test to 2550mAh. I have a feeling the DL24MP is having issues because of the method they are using to connect the modules together which is nothing more than compressing PCB boards together with M3 screws and nuts. I asked them about making tiny bus bars but they completely ignored that suggestion.
