    Zerobreeze AC unit

    Does anyone know anything about the Zerobreeze? Anyone own one? How’s the performance? I’m considering one for my van. Would love to hear any info!

    Strange Multiplus behavior

    I have a 24V Victron Energy Multiplus 3000 and am observing the following issues when connected to 15A shore power and with a 14A current limit on the Multiplus: 1. When there is only a small AC load of 60W or less, the Multiplus (MP) will consistently draw a predictable (and desirable) 1400W...

    Incinerating toilets

    Anyone know why we aren't seeing more incinerating toilets in vans and RV's, now that low cost lithium is putting the requisite power system within reach for many more builders? The incinolet has come down in price also -- I believe it was originally $4K, now $2K. I'm definitely installing it...

    Accessing J1772 (Level 2) EV Chargers to charge Van/RV lithium system

    I've been thinking about this for a while, with a couple of false starts over the past year and a half, but I think I finally have the necessary pieces to make this a reality for my van system (DIY lifepo4, 24V configured as 3 parallel 8S batteries, total of 6.2kwh, Overkill BMS for each 8S...

    Resistors for bottom balancing (25W, 2.7Ω) -- where to purchase?

    Has anyone found a reliable supplier for these resistors that Will recommends? I think I tried to order them once about a year ago and was told they wouldn't ship for 6 months, so I cancelled my order.

    Extending battery life by periodically limiting SOC

    Hi Folks, I have a self-converted promaster van which has 900W of PV on the roof and 6.2 kwh (24v) of diy lifepo4 storage. The van goes through periods of non-use, and during those times, it makes no sense to rev the SOC to 95%+, particularly in hot weather; it does nothing but significantly...

    Future pricing trends for lifepo4

    Where does everyone see the pricing for lifepo4 cells trending in the future, both short and long term? Will we ever see something like $1.00 per Ah (shipping included) or even less??

    Serious problem -- lifepo4 24volt battery (diy from raw cells) cannot charge beyond 59% (2 cells appear to be over-voltage)

    I noticed that for a few days, both of my chargers (victron mppt and sterling dc to dc charger) would consistently float once my battery reached 59%. I finally got around to checking my cell voltages and found the problem -- two of my cells were over-voltage (one tends to go to around 4.01, the...
