Hi,
I'm new to this forum. I recently bought a small trailer to go on short (1~3 day) weekend trips.
I'm thinking of buying the following components for a DIY battery bank:
I'm planning on doing a basic setup without solar first, but want to be able to extend it later with solar and a couple of 12V loads.

I'm new to this forum. I recently bought a small trailer to go on short (1~3 day) weekend trips.
I'm thinking of buying the following components for a DIY battery bank:
- Battery cells: 4x 3.2V 105Ah lifepo4 batteries from Xuba on alibaba (€260)
- BMS: Will's recommended 4S 12V 100A DYKB "smart" bms with bluetooth from Aliexpress (€60)
- Inverter/Charger: Ective CSI 1000W pure-sine with remote (€231)
- (optional) cheap "20A" solar PWM controller mainly to play/test with a 100W solar panel (€5)
I'm planning on doing a basic setup without solar first, but want to be able to extend it later with solar and a couple of 12V loads.
Questions:
- I haven't seen Will talk much about inverter/chargers, nor have I found much on this forum. Are they a good idea? From the website of the manufacturer, it seems like they should be ok to charge Lifepo4 batteries at a 140W rate. Or am I better off getting a separate (and cheaper) inverter and charger?
- Do the components and combination make sense? Am I missing anything?
- If the inverter comes with a fuse, does that mean I do not need to add a fuse between the battery and the inverter?
- Should I connect 12V loads to a fuse box connected to the battery or should I connect them to solar controller DC load connection?
- Most pure sine-wave inverters are expensive. Which appliances are fine to run on a modified sine-wave inverter? Is there a way to find out without buying and trying?
- (crazy thought) Is it possible to charge the batteries by connecting the car's 12V output to the (cheap PWM) solar controller solar-input?
