    Help with Battery meter (golf cart)

    So I got my battery meter for my golf cart through Amazon today. I see two flat tabs where I think will need to connect directly to the battery. My question is, is there a purpose for the two round nuts above them? It looks like they would serve a purpose but not sure what to make if it. TIA

    Now I haven't charged a car battery since my teen days but it seems our two year old car like many now are dependant on a good charge for all the functions to operate, the stop/start rarely works and the dealer who we know told me what I already knew it does not go far enough each day.

    Extra PV system & a wiring issue with battery CT?

    Hi everyone, I have a quick question if I may? I'm thinking of adding a second PV system to my existing rooftop PV & battery setup. As the parts will be second hand due to lack of FITS & poor export prices, I'd like to install as much as I can myself to save money (I've already bought the...

    2017 Isuzu Dmax with a smart alternator. Shunt on the negative terminal of the start battery. The picture attached shows how the Negative from the dc/dc charger was connected, prior to the shunt.

    I have two batteries in a series. The balancer has a black, white, and red cable. I understand where the black and red go, but don't understand where the white "pole" goes. It is only a single cable. Do I need to attach a splitter to it, or do I just attach it to one of the terminals in the...

    I'm considering buying a home battery storage solution and read that with 3kWh feed you can only charge 12kW during the 4 hour Octopus Go off-peak window, which makes sense. Is it the mains supply, battery or inverter that bottlenecks this 3kWh? I've read some batteries (or was it inverters?!)...

    DIY Battery storage system?

    I have an 8kw solar array and I'm interested in a battery. They all seem mega expensive and can't justify the return I would get. I wondered if anyone had built there own battery rack and whether it worked out much cheaper.
