I'd like to power a camping fridge (42W) or charge mobile phones or even power a laptop when staying at a campsite, I have electrics but I'd like to be able to stay away from the power socket occasionally. I was thinking about getting a leisure battery but then remembered I have an expensive high tech battery sat at home that should work much better than a car battery. I can take the charger and top up the battery each day. Everything I want to use is very low power compared to an ebike so shouldn't cause any harm to the battery, I'd also need to make sure the V cutoff is the same as set in the bikes controller.
So how easy would this be, do I need to supply low voltage cutoff or is it built in to the BMS? How do I drop the voltage to a suitable level?
I can probably work it out myself but I'm sure others on here will come up with a more elegant solution and think of safety aspects.
