I have used WW motors with both 3rd party and the manufacturers batteries. 3rd party work just fine but additional victron shunt and misc equipment are needed to accurately read state of charge. With the WW batteries the communication with the display and understanding of state of charge is spot on. The added safety of turning the battery off and shutting power down before the terminal is great. For those interested in the safest battery on the market, this is the only choice. IP67, aluminum case, temperature sensors, its a great battery and the price is very competitive.
