I have two Shoto 6-FMX-100B batteries to be charged by a Smartsolar 75/15 regulator.
On spec sheet float is set to 13,38V and equalize to 14,1V.
To my understanding I also need to specify absorption voltage. Do anyone know what will be an appropriate setting? I assume it will need to between these two?
Batteries used in telco 4G stations and having 12,86V as of now.
Thanks for your advice
It is likely that the equalise means absorption. Some manufacturers use the term interchangeably.
Does the datasheet have a temperature compensation figure?
Just fYi not sure those are for cycling use (statement - floating operational) Telecom are usually designed for float use. The voltages suggest they are not for cycling. I assume you already know that.
Thanks @Alexandra
I don’t find anything on temperature compensation, but full spec and info here https://www.shuangdeng.com.cn/userfiles/4cd5d807dc514b838f58401c8f3a3e9f/files/6-FMX%E8%8B%B1/6-FMX-100B.pdf
A bit unsure on the cycling vs float. They will be used in a shed with occasional use (shed outside my cabin) for led lights, a china diesel heater and a small inverter (500vA phoenix). So I don’t expect many full cycles.
Will be fed by two 75w panels in series (due to darkness at winter in Norway)
You are right not much useful information.
The temperature will mainly be quite cold (650m above sea level and Norway is generally cold most of the year) and the inverter will mostly be used for small power tools like Dremel, charging some batteries and so - hopefully It will work ok.
Thanks for the replies and useful information.
Ok. Well maybe use the AGM spiral preset setting and just adjust voltages accordingly.
I don't have personal experience with that particular brand but it works well for other AGMs
Alternatively you can try contacting the manufacturer for more information
Solved. Details available here https://www.enervision.co.za/wp-content/uploads/2018/10/Shoto-6-FMX-Installation-Guide.pdf
