February 3, 201610 yr Author Update: Max Mid Point V spike today on Grid Charge @ 20A is 0.5% (previously 2.2+%) Yesterday: 0.7% Monday: 2.9% Sunday: 2.5% Saturday: 3.0% OK... weather was very hot the weekend and Monday so I will need to give things a few more days. That is the sort of change I achieved over 3 or 4 months. The balancing achieved by paralleling is obviously helping. Paralleling without a battery balancer would just be asking for trouble.
February 3, 201610 yr 360ah 6v L16RE-B 1,600 CYCLES @ 50 % DOD - WITH SMART CARBON Price wise, what are we looking at? R 4 742.51 incl VAT per batt.
February 3, 201610 yr Bad news is that it is a lot of money for a 48v batt bank. Good news is that it is 50% cheaper on a 24v batt bank. :-)

February 4, 201610 yr I have taken the plunge and installed a state of the art battery temperature monitoring system on a battery on the bank. The challenge has been to do this without a BMV sensor as the MidPoint Voltage is more NB for me on the BMV702. It took a while to install but Chris Hobson will be proud ("draadkar" haunts me ) Called the BOYU BT-05 Aquarium Digital Thermometer The term digital can be taken with a "sack of salt". Could only afford the 1 but plan to buy another if this works... R29.90 wow...
February 9, 201610 yr So now Mark you are forced to don the guinea pig ears and try. I think if you fuse the wires one would be safe. Fused each positive bridging wire (between banks) with a 5a fuse. After doing some measuring at different times and mid point voltages I see I don't get more than a 0.5 amp flow on these links. Some insurance (R50) is never a problem. My average daily MidPoint Voltage has settled at between 0.09% and 0.16% (from between 0.25% and 0.5%)
