How more capable? Just not having the extra draw?
The issue is the inrush current to the 3000W inverter caps trips the high current protection in the bms.Weird. I have the BT heated 100AH 12 V and can power up a hair dryer taking 100A with no issue. Maybe way less surge? I'd be lost without the BT info, really helped me understand the draw from different loads in my camper. I suppose I could have gotten this information in other ways, but just really convenient.
I have a precharge circuit for the inverter. As long as I use it I am fine but if I forget, both batteries will go into protect.That makes sense. I know for a fact that the 12V 100AH heated version cannot handle "Peak Discharge Current: 200 A (7.5 s ±2.5 s)"
How did you get around this?
Yeah, the EasyStart is the key there.I’ve finished my system now and my pair of 206Ah with the BT BMS have no issues starting my 15k A/C(or running anything else) from a MultiPlus-II 3000 120x2. I don’t have a pre charge circuit. I do have an EasyStart installed in my A/C unit.
Oh yeah. I consider an EasyStart to be a requirement for running an A/C unit on any inverter or generator.Th
Yeah, the EasyStart is the key there.
I only run the A/C on the generator for now. Have a predator 3800 and it seems to run the 15KBTU fine. Would I still see some benefit to the easystart?I have an easy start on both 15k air conditioners. That doesn’t help with the inverter caps, though.
Only if you want to try to run two air conditioners off the generator. That would be tight even with soft starts. If you only have the one ac then you shouldn’t need a soft start.I only run the A/C on the generator for now. Have a predator 3800 and it seems to run the 15KBTU fine.

What inverter are you running?I have an easy start on both 15k air conditioners. That doesn’t help with the inverter caps, though.
Same as yours. If I turn the solar on and there is any sun at all, I don’t have to precharge. Or if the truck is running and hooked to the trailer. But without help, both of my batteries will go into protect if I don’t precharge the inverter caps.What inverter are you running?
Interesting. I don’t have any issue even with the solar controller breakers flipped off. I wonder if it’s a difference between BMSes or MultiPluses?Same as yours.

That is a great question. I can live with the need to precharge. I would really like for the inverter not to buzz when on shore power. I have isolated it to the charger. I wish I could just turn the inverter off when on shore power, but the ATS doesn't work without the inverter turned on. I can mitigate it during the day and set the inverter to charge only with the solar on. I set the float voltage on the inverter/charger 0.1V lower than the float voltage on the SCC and that keeps the inverter/charger from turning on which eliminates the buzz. But the charger still comes on at night. Might have to set the inverter/charger float down to 13.8 when on shore power.Interesting.

Just did a build with 2 SOK 12V 100Ah, Heated w/ Bluetooth batteries and a Victron 2K Multiplus, a Victron Orion TR Smart, and a Victron SmartSolar 100|30
When you receive the SOK bluetooth battery, please search ABC-BMS on google or apple store and install on your phone, but the SOC and capacity incorrect, have to do 2 cycles.
Few steps to do this:
1. Check the voltage on the terminal, it should be 10V~14V
2. discharge it, using a 12v DC load connect with terminals directly, let it working till it stop, after fully discharge, the BMS should be cut off, the Voltage on the terminals should be 0V.
3. Wake up the battery: connect a lifepo4 battery charger on the terminals, it should be wake up back to work, BUT not all lifepo4 battery charger could wake up the battery, please check this video if wake up not successful: https://www.youtube.com/watch?v=TJ_Klwp-JyM
4. After you wake up the battery, connect with the lifepo4 battery charger, let it working till BMS cut off.
5. Repeat the step 2, still using a DC 12v load discharge it till cut off.
6. Repeat the step 3, wake up the battery.
7. Charge the Battery , check the app, the SOC and capacity should be correct.
