Not sure about the experience of others with the Brightway (Chinese made) batteries, but if yours are more than a couple years old and you depend on them for boondocking - you might want to think hard about replacing them sooner rather than later. Ours failed in about three years with very little use, as we mostly camp with FHU. I had difficulty removing the batteries recently, as they had swollen up and wedged themselves into the battery box. These batteries were not high quality - a concern I expressed to Anita when Oliver made the change from Trojan (in 2020 as I recall). This was an expensive upgrade, clearly not worth the cost.
We just bought three BattleBorn lithiums and will install them soon. Yes, I know we need to change the converter configuration for the lithium batteries.
