Hello, I have NKY226B02 battery and NKJ039 battery charger. The battery was dead so I send it to the regeneration. After the regeneration I put the battery to the charger and it's charging very slowly. I measured it. There was 27,4V and 0,135A (charger is 29,4V 1,8A) - maybe the charger is faulty also. I put the battery to the laboratory power supply. I put on 29,4V and 1,8A. At the start the battery takes something like 0,175A and after one second it's disconnecting charging. Do I have to put some voltage to the third pin, (between third pin and negative is 10k Ohms - guess NTC sensor) to force the BMS to charge? I'm so confused because I don't know that something goes wrong with regeneration, the charger lost the current efficiency or what? Please if You can give me the advice, since I have no experience with that type of electronics.
Hi Battery Doctor, Thanks for the video. I have an old NKY190B02, which is empty. When pressing the button at the battery, the LED's are wandering from (E)mpty til up (F)ull, . Connected to the charger for hours, it is not charging, since the behaviour of the LED stays the same. I have another old battery NKY177B02, which still works, but has a very limited range (5-10km). There I the charger works. My options are: - replace the lock of the battery, so I can buy a newer 26V model - replace the cells in the NKY190B02 What do you suggest ? Could you provide me links where I could buy another battery lock system or the replacement cells for NKY190B02? Thanks in advance
Hello I have an old Panasonic E bike with a battery that has a smidgen of a charge it is NKY214B02 Have you had any experience with this battery? The bike fits me perfectly and bought along time ago in Japan. Thank you for any advise.
Hello Battery Doctor, thank you for posting this one :). I have bought a flyer bike , and have a NKY190B02 which basically is the same as that one, but with another brand (Biketec). Its from 2008 as well, and the battery still has around 15% capacity, charges and Im able to use the bicycle for around 10 km! I will try to replace the cells, but there is an overwhelming amount of info on how to do this so im a bit confused. I can simply replace the cells and use the same BMS and the same charger as long as I keep the same configuration? Thank you very very much and keep up the great work
@@Batteridoktorn So when this original has 2 separate 7s pack with both having their own bms, you have to do 2 separate 7s2p packs instead 7s4p beacause of the 2 bms?

Hi, do you have a wire diagram from BMS, please? Well thank you.
