Hi
Looking at possibly buying an Ohmmu lithium (LiFePO4
) battery to replace the OEM one in my Model 3. The car is approx 18 months old and from what I can see from stats it has started waking up to top up the 12v battery every 24 hours, so I don’t think it’ll be too long before it says it needs to be replaced…
I tried reaching out to Sean @ Ohmmu to ask a few questions but got no response, which is a bit of a concern (e.g. for future warranty claims). I’m hoping some existing owners might be able to help.
I’ve got an automatic trunk and frunk kit fitted to the car. I’m led to believe both draw a nominal amount of power when idle, but it’s obviously enough that it is draining my 12v enough to need topping up. I should say that I barely drive my car, which possibly isn’t helping. I’ve done just over 2000 miles in those 18 months, and quite often won’t need to drive it for weeks at a time.
I’m keen on the Ohmmu on the basis that it should in theory last longer between topups, but at the same time I’m worried that the usual battery topup procedure doesn’t work with it? How does an Ohmmu fare in a lightly used car?
Also it gets pretty cold over here in the UK. Sub zero temperatures are common in winter, although they aren’t usually more than single digits. Bearing in mind the above is it possible that the car wouldn’t be able to recharge the battery if it’s too cold out, and therefore might go flat?
Thanks in advance for any help provided.
