Chinese companys to avoid

[m3vuv]

Hi all,just a warning about a chineese bms company to avoid,about 7 months ago i brought a smart bms from a company called MGOD on aliexpress,it was a 20a 13s unit,,it arrived about a month before the cells i had on order.

Anyway i built the pack and fitted the bms,checked it all with a multimeter,all was ok,but no output no coms via bt or uart,long story short its been about 4 months of trying to get them to send a replacement,they keep sending me in circles,and keep changing the people dealing with it,i had to buy one from llt,that one is wired up exactly the same and works perfect,so in a word i have been shafted by them,it never worked since it was unboxed,spread the word folks,lets name and shame the turds!

Thank for the info, I am looking at a bms for a build and am concerned about learning the hard and expensive way.

You're tilting at windmills. The sellers who use AliExpress are not concerned with reputation, and they have pretty much zero incentive to stand behind their product. If you keep shopping there, you are going to keep getting learning opportunities. Will you take them?

maybe but its to warn others,its the only issue ive had with aliexpress,cant say that with ebay tho!

Jiabada is the producer or just JBD
ICGOGOGO also sells these BMS with displays that only work with their BMS (maybe custom firmware?)
and then there is also LLT

The first 4 results on ALI feature these sellers.

I will not consider purchasing anything from AliExpress because they fill your in-box with SPAM emails. I can deal with Amazon, Ebay or even Banggood and not have to deal with an avalanche of SPAM.
