The problem I have with relying on simple pack voltage measurement to control
the charger is that eventually, as the pack ages, one or more cells are going
to go out of balance, become the 'weakest link' and cause the capacity of the
pack as a whole to unnecessarily reduce. From a safety
Hi Rick and All,
Thanks all for the experiences so far. I appreciate it
as do others.Please let us know how yours is working with lithium charging
too as we need a good sample as we need a good low cost wthr meter especially
with adjustable relay

How do you find the LED display does in bright sun?
Anyone have a nice LCD energy or AH meter they like?
Any feelings of
I've got the Blue LED version. No problem seeing it on sunny days.
Kinda too bright at night though...

It is just a panel meter. I use one to turn off my charger. It has worked fine
for that and it seems accurate but I haven't compared it to other data.
Capacity is another issue since it drops slightly with every charge and
discharge cycle.
It will keep good record of what was put in. I haven't
I'm using the DC AH meter. I'm not currently using it's relay outputs for
anything.
The AH counting seems to be at least consistent, though since I don't currently
have any other meters to compare it to, I can't tell accuracy.
I generally use it to tell how many AH's I've used - pretty much as
Using a meter to turn off a charger at a pre-programmed voltage can be very
risky. A BMS is designed to perform this function, but turns off the charger
when a single cell reaches the pre-programmed voltage, after permitting all
cells to achieve the same voltage by shunting. It also protects
Problem is no one has actually proved that with experimentation. Not in any of
my reading. You can believe what ever you like.
I have used ammeter for 2 years now. The voltage always end exactly the same.
The next day the pack is the pack is exactly 147 volts.
I have never seen any study done
Jerry,
I have several JLD temperature controllers in service about my lab and they
work flawlessly so far. Based on their performance I happily bought the
WattHour meter, but I haven't really used it yet. For the cost they are
certainly worth a try.

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.
I skip constant voltage. My cell voltage at the end of charge is 3.34 volts
after settling for several hours.
When I use cc - cv mode they settle to 3.38 volts.
You don't loose more than a couple miles range by skipping the cv mode.
