Did a capacity check, got 262 ah, used a heat gun pulling 100 amps, inverter cables got warm, bms was warm but not overly hot. Pretty sure it would have run 200amps as advertised. That was with the old battery and a 280ah eve cell that I had to replace the bad cell. I used short pieces of #4...

The new battery seems to be doing well. Actually bought from Ebay. Used a 280ah eve cell I had to jumper in the bad cell in the old battery to test. Rest of the cells are nicely matched, 20mv highest to lowest not counting the eve cell. Will run a capacity test once new battery is charged ...

They use cells I've never seen before, long flat with a 4 screw plate on each end. Looks like a solid bms, has balancing and dual temp sensors, looks like it to starts balancing at 3.4 , that's when the Led's on the bottom of the bms start lighting up. Cells are compressed using metal strap...

If you can find an older version of the Vestwoods app it actually shows individual cell voltages.

Won't charge , cell at .211volts set my power supply to 3.6 and the bad cell won't take a charge. It happens, Vestwoods did right by me, sent a new battery and told me to dispose of this one. Couldn't ask for more from yhem.

Already did, didn't have to cut, they used rubber gasket to glue it. Has a bad cell just as we thought.

They warranted the battery and are sending a new, told me to dispose of old one.

My 250 ah ultra has one cell at .8 volts and the other 3 at 3.7, charged it once, discharged @ 30 amps for 4 min twice and got low voltage protection and over voltage protection turned on at the same time. Discharge and charge are both turned off. Now they want me to pay $150 to ship it back.

Well my concerns were valid, the Vestwood 250ah 200 amp bms Ultra failed after a day or so. Charged it fully when I got it . Put it in my camper, converter set to lifepo4, turned off converter, ran the slide out out, takes 30 amps. Ran the slide in and the battery low voltage protection tripped...

Yup, I boondock fairly often and I needed the extra capacity. It's nice to have the outlets available even though most of it is on 12 volt or propane including the fridge. I have 300 watts of solar on the roof as well it won't totally keep up the batteries but it helps. I use a suburban furnace...

It's a Dometic 8k btu, I've insulated the Sprinter, the outside temp was around 85 and I kept the inside at 72-75 or so. It cycled on for 30 mins or so then off for 15 . I don't keep that close an eye on the specifics. I have a 3500 watt aims inverter that I run off the batteries.

Not Calif, northern MN 8k btu ac.

I built my own battery's, 280ah and they are half the size and a quarter of the weight of the Vestwood 250ah battery. I have bluetooth, balancing, low temp protection and a heater if needed. I ordered a Vestwood 250ah for my full size camper, i didnt have time to build the battery bank, and the...
