This a great relevant thread for me. I'm interested in going from Lead to Lithium on my boat and I believe Volt cells are likely the most available and least expensive to me. The Volt cells appear to have different charge points than most Lithium so the HB404 looks like a great solution. Jerry, do you just use one HB404/ contactor for a string of cells that add up to 120v when charged? No other BMS? I'm looking at doing 96v setup, doubling my current 48v setup. I was thinking 2 x 48v packs, 2 HB404s and contactors and using 2 x 48v chargers that I already own. Appreciate any advice on this, excited to switch to Lithium but nervous of destroying a set in the learning stage lol.
