Cheap Lifepo4 charge cutoff module discovered for Sterling B2B Charger

[dbjensen]

I'm using a Sterling Pro Batt Ultra BB1260 to charge my Calb 160ah 4S bank. I discovered a cheap module on Aliexpress, Ebay, Amazon. I call this module a charge cutoff module because it has a voltage sensor and timer. The input senses input voltage from the LFP bank and the relay output connects to the BMS2 input on the Sterling Pro Batt Ultra. I'm also wondering if any of you have managed to turn off the Sterling Charger by just programming the charger in a custom setting.

I have created 2 videos showing my setup and I'm looking of your input. I may need to coat the board to make it waterproof.

Here is the charge module setup

This are a bit more money, but are way more robust. The 65A version runs about $40ish on the web and they make a 100A and 165A version as well. Some even with bluetooth for programming and monitoring.
