I have a JLD-404 that I use as a fuel gauge and it's worked flawlessly
for that. It seems to be pretty accurate. I have bought things from EVTV
even though they are more expensive than other sources, but these I buy
right from lightobject because Jack has cranked up the price way too
much. Their shipping is fair and quick.
I also use one of their JLD-612DC temperature controllers to control the
water heater in my truck. It too works well.
A problem, however, with controlling a charger is knowing what to
trigger on. The normal charge scheme is to charge to a certain voltage
at whatever amperage you can manage and then hold that voltage and taper
the current off to some small value. I don't think you can really
duplicate that. I suppose you could turn it off at some voltage and when
the pack voltage drops (which it will almost immediately) turn it back
on until it stops dropping below the threshold.
You could trigger on Ah but I always put more in than I took out so
that's problematic too.

Hi All, In my continuing fight to lower lithium battery pack costs I
was wondering if anyone has experience with the Lightobject Wthr ,
etc meter like the one EVTV made the vid of they rebranded?
Especially interested in it's use turning off the battery charger and
how well it keeps track of battery capacity of lithium packs, etc?
Thanks,
Jerry Dycus
