Description
Hello,
I need a battery capacity / current monitor for a portable battery pack.
The packs are 48 volt, 12 Ah, max current 50 - 100 Amp. I need a meter with digital readout on LCD that displays things like capacity remaining %, used capacity Ah / Wh, and time left to empty. Must be programmable for different capacity packs.
PLease give me indication of price for the design, the prototype, and a small series of 100 pieces, delivery time, and delivery conditions.
If you have an existing design, or know of one that meets the specs, this is also acceptable.
Thanks, Richard

Hi: Basically you need a low power current monitor (BQ27500 <2,5$) a low power microcontroller (<3$) and a low cost LCD (<6$) and the PCB (<4$), and the manufacturing (<20$), then in production it will cost less than 35$. It is no problem to change the battery characteristics. Regards from Spain.
