I do not have my system here to check if I see the setting. Section 4.1 manualI’m not seeing “battery start synchronized”?

Sorry to hear that. What brand?Unfortunately the free charger doesn’t work.

Yes. This exactly. Especially with lower amperage chargers, less opportunity to see upper end charging voltages because they are amperage restricted.The converter or charger will only try to get to 14.4V but will only go as high as it can until it hits the max current output. In other words based on the max current of the converter or charger, it may or may not get to 14.4V. As the battery voltage increases due to charging the converter or charger will final reach 14.4 V but at that point the battery will be charged and it will drop down to 13..6V. The output of the converter will only reach 14.4V once the battery is consuming less current than the converter or charger can supply. With no load, the converter output should be at least 13.6V for a lithium converter or charger. See voltage graph from my converter for reference (tap the picture to see the entire charge cycle)
I'm not so sure about that. I paid an enormous amount of money for a ball cap. Fortunately, I got a free house with it.Nothing in life is free...unless it is worthless...lol
Don't know if it is useful information to you @dryfly , but with my 20a LiTime charger I do see over 14 volts nearing the end of the charging cycle before indicating charged. For how long? I don't remember. All three batteries are non bluetooth, 100ah batteries and after resting for a while sit around 13.5vdc.
Sounds like you're satisfied with getting to about 85% of capacity, if that's the case that's fine. I'm curious what you are seeing with the Bluetooth app on the battery. Can you see the voltage of the individual cells? If so, what is it saying? I'm just curious at this point.I'm still testing. I did see 14.1v nearing the end of the charge cycle with my 200watts of solar. Resting voltage was 13.4v. I think everything is going to be acceptable with this battery.
I got a different 20a charger and I will charge with it today. Still trying to get a handle on the exact amp/hr capacity of the battery, but I know I'm getting over 85. For my purposes I can live with that.
LiTime app does not show voltages of individual cells. The BT does not have any settings and show SOC, Power, Current, Voltage (total), Ah Capacity, Temperature, Cycle Times (number of cycles), serial number and Firmware Version.Sounds like you're satisfied with getting to about 85% of capacity, if that's the case that's fine.

This battery does not have BT capability. And, as Tim says, individual cell info not available on LiTime batteries that do.Sounds like you're satisfied with getting to about 85% of capacity, if that's the case that's fine.

Sorry, it's a bit confusing. I forgot we're talking about different batteries that you have vs your neighbor. With a new battery, you should get at least the rated capacity and almost always it will be a bit higher than rated if it's a good/reputable battery (or cells if DIYing). The only way you can really know for sure on your battery would be to get it to a full charge which will be 14.2V - 14.4V for bulk stage, then it should charge at a constant rate (what we think of as absorption for lead acid, but absorption is really applied to lithium) until it reaches 14.6V. At that point the voltage will decrease until the BMS stops accepting a charge. Getting it to full charge also balances the cells.This battery does not have BT capability. And, as Tim says, individual cell info not available on LiTime batteries that do.
That is what makes my life interesting. I know stuff works but I am interested in how it all happens. Just because someone say's something is not a good enough reason for me to believe.Well, I don't know about being diligent. It's more just being interested in how stuff works.
