Hey Will. Here is a video request for your consideration. Off grid 48v system capable of autostarting a backup generator to recharge when bank is low. I wonder if there are any all in one systems capable of controlling a generator? My winco standby generator has a two wire auto start feature...

I thought I would post what I think are some pros and cons of the Orion Jr 2 BMS. I have been running it for about 10 days now. Pros: Very accurate monitoring of cell voltages and DC amps Many many settings and options allow you to customize everything to fit your needs I can connect a laptop...

Just installed a 48v 400 aH LIFEPO4 bank and orion jr2 BMS. The DC current is highly variable. Screenshot below. There is some solar charging going on while the inverter is also powering some loads. I sent this image to the tech support of my Magnum inverter just to make sure this was normal. He...

Anyone here familiar with the Orion Jr 2 BMS? I am setting it up to test how it works on a small 12v pack (4 100ah cells in parallel) I am attempting to use the CANbus adapter to connect it to the computer to program the BMS. I get an error message saying it cannot connect. I checked the wiring...

Theoretically when you put 4 cells in parallel, the voltages all are the same. However, under charge/discharge each cell wouldn't each cell potentially vary (pun intended)? I am looking at buying an Orion BMS and one model would allow me to monitor all 64 cells. That might be good so I would...

I think most people are charging their banks to a capacity of 80 to 90 percent in order to extend the number if cycles the bank will last for. In order to measure capacity, a shunt/coulomb meter is typically used to count amps in and out and display state of charge. These systems require a...

If you buy chinese batteries do you have to pay an import tax?

I am about to order a Daly 200A 16S BMS from Aliexpress but cannot tell if the 16 battery terminal lead harness is included. Anyone know? Thanks!

I thought it would be a good idea to have a thread where users share their mistakes/lessons learned with others. One of the mistakes I made was fairly simple but had serious consequences. Looking back now there were some big clues I was missing but it took me too long to discover the source of...

First off: thank you to Mr. Prowse for all of the information in your videos, website and forum! My 48v 860ah lead acid bank is almost shot so I am replacing it with LiFePO4. I was considering buying simpliphi batteries but I think that DIY looks like a good option and it should save a lot of...
