The BMS we choose is Super Power brand non-smart 13S 30Amp, no balance function. The Samsung cells voltage consistency is very good, so the balance function is not necessary.I'm just wondering.
Does the battery's BMS balance the cells?

All our ebike batteries use the Super Power BMS, basically no defective products.
For BMS with balance function, the balance voltage is usualy set as 3.8V, corresponding about 80% capacity.@Jenny Mao
I have another question.
I found this quote here on EBR,..
"Charging to 100% usually forces the BMS in most batteries to balance cells. Charging to 80% is fine and may improve battery life. Charging to 100% occasionally is a good idea though"
I was wondering if the BMS in my battery will "force the BMS to balance cells" ?
I am intending to keep my battery charged between 20% and 80%, and occasionally charge the battery to 100% to "balance the cells".
If charging the battery to 100% serves no purpose, then I may not charge it fully.
It is okay if you can easy control to charge to 80%.I will charge to ~80% using a timer, then fully charge just before the ride.
Hello Jenny!This is a Dorado 25Ah capacity testing , 24.5Ah tested
Hello Jenny!
I am interested in Aijiu energy batteries and I have a question for you:
You say that you can get 24,5Ah from 25Ah 48V battery. But on one other thread about your batteries, you have also said that you get average 24.182Ah x 48V = 1160Wh under condition of 10A discharging. There is of course some variance between batteries and not all are exactly the same capacity when measured. I am interested about what is normal range in true measured capacity in 48V 25Ah advertised batteries? What would be considered lowest measured Ah that you still consider "good to go"?
hopefully you emailed her. this is crazy busy season.Hello Jenny!

@Bitmugger thank you for your answer.
Actually, I forgot to mention that I already got myself both 48V 25Ah and 52V 20Ah batteries from Jenny/Aijiu. I am happy about how they are performing, and I was just genuinely curious to hear what is the acceptable true measured Ah range of these batteries.
So, @tomjasz I am not in a hurry to get an answer from Jenny. I can wait as I am not in the middle of buying new battery at the moment.
According to test reports my 48V battery has 23.81 Ah, and 52V has 19.12 Ah (if I read it correctly, as the last number written was not wery clear). Not as much as @Bitmugger got but ok. Actually that is quite near to that "in spec" value of 4753mah. If that is the minimum requirement for Samsung 50E, then my battery is quite close to meet that.
One thing I could have hoped to be different was, that I would have wanted bigger BMS. Even just 40Amp instead of 30. I am not sure, but if someone can confirm: Is there room in the case to even fit bigger BMS than 30A? If there is, then I suggest to make it possible to choose between different rated BMS versions with these batteries.
Hmm.. Do I need, or do I want oneA 30amp bms will handle a 1500watt motor, you sure you need more than that?
For capacity we are comparing real-world conditions of a battery built from 60+ cells and a BMS that will cut you off below certain conditions versus a spec sheet for a single 50E cell so some variation and losses should be expected. I haven't measure the real-world watt-hours on the 52v yet but I just need to remake a cable and I can test mine soon
Thanks for your support! According to a lot real testing experience, the qualified standard capacity is set as mininum 95% of 25Ah, that is 23.75Ah. But the testing result will the influenced by many factors like the environment temperature, the discharging current, the testing machine deviation.@Bitmugger thank you for your answer.

13S or 14S 30A BMS is max regular model BMS we can find to make it fit in the Dorado 21700 case, where there is only a very slim but long room for BMS.One thing I could have hoped to be different was, that I would have wanted bigger BMS.
