Re: Electric Conversion log for Kahleesea
I need some opinions, guys.
The Particle photon runs on 3.3-6.5 vdc. 5.5 is recommended.
The only solution I can come up with to keep it powered 100% of the time is to run it off of the battery itself through a DC-DC converter. Is there a better way?
I'd like to run each battery on it's own BMS, but I'm having a hard time finding relays that work off of the particle's 5v 100mA output. There are tons of them for 120V, but when I start looking for 48VDC 200A relays, I only find relays that the particle has no hope of pushing closed. If I use a 120vac relay, that means either one battery shuts the whole pack down, or I need a charger for each battery. It would be a lot less expensive if I could just find a relay for each battery. While I'm sure using one BMS for the whole system would work, It's more optimal to do a bms for each battery.
As always, I'm open to ideas.
