Ebike battery as a power source??

[SanSan]

A bit of a techy question- we are moving to an eco-cottage soon and I wondered if the bosh ebike powerpacks could be used as a power source.

We have a sine invertor but is there a way to "fool" the powerpack into delivering power whilst off the bike??

I'm curious to know more about what you're trying to do. How are you going to keep the battery charged?

There's probably a way to get power out of the battery but it's almost certainly not going to be the proper voltage for your inverter. Since you're talking about an inverter, I assume you want to go from your battery through the inverter to get 120v AC? If that's right it will be way more efficient to get your AC straight from where you plug in the charger for the battery.

What's an eco-cottage?

Good question. On a 500 watt Bosch inside the back of the frame, what are the connectors plan ? Which terminal has what ?
Thanks

There are options for inverters in various voltages these days. I will soon have a 48V inverter. A Bosch battery with a com system is the last sort of battery I'd use for inverter power. Risking damage to the BMS and bricking the battery would be an expensive lesson. Better to have a separate battery for power use. Consider the many groups discussing 18650 battery packs for power. See https://www.facebook.com/groups/Vruzend/ and https://www.facebook.com/groups/202140770347162/
Keep the Bosch battery for transport. This is one of the scenarios where I'd buy a pack from a better known Aliexpress reseller like UPP. A soft pack can be pretty cheap. OR building a power wall with Vruzend's latest kit is another great option.
