StarkPower Bluetooth LiFePo4 App. I have 100Ah & 50Ah batteries, connected in parallel, in my FWC battery box. I purchased both about 1.5 yrs ago, same generation, parallel compatible.
I am not that handy. When I found out that internal Bluetooth existed in LiFePo4, I saw it as an opportunity. I did not have to buy a Victron battery monitor, mount it or wire it, add it to an already, for me, complicated wiring task. I am now a bit more confident. StarkPower has gone out of business, but, they were in business for some years, & I am happy with my purchase. I followed an earlier FWC post, the op a LiFePo4 pioneer, had owned SP for 2 years & was happy. There were Positive reviews about the company on the net. The owner was a former automotive industry innovator. Oh, also, they were priced ~$150 less than the competition, among several that did not offer Bluetooth. After buying the 1st Battery (100Ah), I had reasons to add more Ah(50) & to have separation. I asked for a discount & received a 15% off coupon code. It helped.
Two issues give me pause ... Will my SP App last “forever”?, 7 years is what I hope/expect. The 2nd issue occurred to me with this post, w/o the use of my phone for some reason, I will have no monitoring capability because I do not have an independent dedicated monitor.
Below are some screen shots taken off my iPhone SP App. #1. Both devices shown. #2 & 3. SOC, voltage, status, health, capacity. #4. Temperature & cycle life. My battery group has been through five cycles. #5. Real time individual cell activity. The tech is cool, it’s internal, it’s live. How long will everything function at a high rate .....
