I thinking of getting an BBSHD ebike kit and an EM3EV 52v 17.5ah battery. The battery has an 3 pin plug for charging but wondered if the battery could be changed via the Anderson plug feeding back through the BMS? - 'in reverse'
Charge via Anderson plug

Thanks, Looks like the answer is no you can't discharge and charge on the same port with the EM3EV battery.
Why it is, I can get a charger for cheaper than the battery supplier but it has an Anderson connector on it. The generic? one on the EM3EV I can't seem find a supplier to change the from Anderson on the cheaper charger.

Don't know what a "3 plug" is, but if it's a male XLR, then you could buy an Anderson to XLR adapter, make one yourself, or just cut off the Anderson and solder on an XLR (which is what I did on my last charger). Changing out connectors is normal course of business for DIY ebiking, so I think it's better to make purchases based on specs and features, and accept the necessary evil of changing out connectors.

Sorry that should have been ' 3 pin plug'
I've just come across this thread about the plug https://electricbike.com/forum/forum/main-forum/general-discussions/116351-can-you-help-identify-this-charger-plug and it appears to be a generic. I'm familiar with XLR plugs and most power plugs. No problem for me changing out the plug - I'm into electronics.

:lol: I know, I can get a charger from https://www.aliexpress.com/item/4000074772442.html?spm=a2g0s.8937460.0.0.3f382e0epzSMmF for more or less half the price of one by company 'X' and it would be nice to use the original plug on the battery but can't a supplier of the 'proprietary' one on the EM3EV battery

I guess the other, but less desirable, way to go is the change out the connector on the battery. Do you have a picture of the EM3EV connector?

No I don't have a picture directly as I don't have any ebike bits yet. I'm just pricing up the bits and pieces and working out the cheapest and best option. This is from the link a posted further up but it's not my picture https://imgur.com/59lLQ67
It might be best to get the battery and charger from the same company, at least that way any potential warranty issue with a separate charger wouldn't be a problem. 'Yes sir, but you didn't use our 'special' expensive charger' .....

There's several reasons, but one reason not to share power and charging ports is they need different levels of fuse protection. A high enough amp fuse for the power wires is too high to protect the charger wires typically.

17.5Ah of 35E would be a 6P pack. Per the spec sheet you referenced "For cycle life : 1,020mA", so 1A x 6 = 6A charge rate for better cycle life. 5A shouldn't be a problem.
EDIT: sorry, messed up the math, 17.5A of 35E would be 5P, so good for 5A charging.

The '17.5Ah' is a 14s5p pack although I think it's actually a 17Ah pack(just checked it's 17Ah), either way charging at 5 amps would be fine.
