The thing I am noticing about these systems is complexity. All the
different sense wires and circuit boards associated with maintaining
charge levels on individual cells. I guess the auto groups have been
hammering reliability, but what about deployment into the off-grid
space, is it robust enough?

Ray,
I had a 100AH battery for about 3 weeks of testing. I worked it hard. I even
over discharged it once. It worked perfectly at different charge and discharge
rates. The most interesting thing was that the 100Ah battery regularly provided
115AH at 95% DoD.
I would sell the CALBS but, again, the US distribution is only through other
dealers. There are several people importing them but they all teated me like
the end user or consumer. For off grid use, the Lithium battery industry has a
long way to go to make these mainstream. I hope to change that some.

Larry;
You mentioned you tested CALB batteries; what was your experience with them?

Jay,
I'm an authorized dealer of GBS systems and we stock and sell them here in our
retail store. I can build any voltage bank in 12 volt increments. All our
systems include EMS computer, cell level balancing, temperature and SoC
monitoring with over/under voltage protection. Basically a turn-key setup.
We tested CALB for a while and tried to get other lithium brands in but the
distribution market in the USA is a horrible mess when it comes to Lithium
batteries. I got frustrated after trying to communicate with importers and
choose GBS because they had the best and most intelligent response to me. GBS
batteries are LiFeMgPO4 or LFMP which is safer, won't catch fire. When
comparing life cycles, LFMP is lower cost than any lead acid batteries.
If you're interested, I can configure a system for you and get you discount
cost for resale. Contact me off the board.
