third party charger for 36v

[biketothemoon]

hi,
Can anyone tell me if I can use this Chinese charger without major problems:

for this battery, "California" "Advanced Electronics Energy Limited" "AEPCM100136V10AH000360" 36V?

The connector looks like it might fit and I'm assuming they are sort of standard so if it looks right it probably is.
The charge rate is slow...maybe I need a faster 4-5A charger to avoid damaging the battery, like

The battery is for various projects that need 36V, not necessarily an ebike, so bike considerations are not that important, in case there are any.

greeting im new to ebike but im clued up up on lot of stuff...so for what i see with the link you provided you look good..as you have a 36v 10ah battery there the connecter looks good the charger will run 36v and by looks of it it will run 48v as well
and yea the charge rate on charger is only 2amp..maybe look at 3amp charger

thanks for the reply. Have you ever used a Chinese charger on a battery pack?

 

[Jacko]

no i have not ive just got a ebike recently ..the only issue i can see for your project is it a chinese charger..maybe see if you can get a charger more local to your area as if you do have to return it it would be less cost

just be sure that the chinese charger has the hot wire the correct one.
Sometimes they do their connections Backwards from us in the US if you bought the battery and charger from them.
Also if it has a brown wire that sometimes is the hot wire....be sure where your wires go and which oines they are
with a continuity tester before you plug things in.

Search for the battery specifically for Li-ion and the exact voltage, not just 36V, it can be written something like 37.8V which is 4.2*9.

I'm not sure what you mean. All the info I have I posted in the original message. Beyond that, and I searched a lot, I have no extra info.

thanks for the reply and tips.

I mean you have to know the exact voltage or series number of your battery, like 58.8 - 14s or whatever, to the very 0.1 volt near, and get any lion chargr with that volt number in the advert.

Some of the concerns I have is do you know the exact charge port pin assignment? If not you can not possibly safely choose a replacement charger. If you are not knowledgeable these testing procedures I would suggest you find someone that has the experience to safely test the port on the battery pack.

Once you have that information you will need to find a charger that not only has the proper voltage and amp output but matching plug configuration. Unless you know the cell makeup of the battery pack I would caution you not to try much higher charge rates (i.e. amps). This could result in permanent damage to the battery, maybe even a fire.

You need to know the chemistry and series count of your battery.

I would start with measuring the voltage of your existing charger, 36V for li-ion is 42V output, 10 series strings at 4.2V, generally, but there are numerous possible variations. More likely to do damage with TOO MANY amps rather than TOO FEW.
