Busbars will make a battery rack run more efficiently.
In part 2 we wired the rack of Jakiper batteries as a "daisy chain". We saw the wires were getting too hot in that setup. Now we re-wire the rack to a central busbar and re-run the load test. WOW! The results are amazing.

Jakiper (Orient Power) sent me some of the new "PRO" batteries for testing and review. This is Part 3 in the video series.
This battery is part of the Jakiper line. Model# JK48V100PRO Server Rack design. The cell chemistry is LiFePO4 (Lithium Iron Phosphate) which is the leading chemistry for home storage. Each battery works with 48V equipment but is technically 51.2V nominal, 100Ah. This means you have 5.12kWh of capacity.
There are 4 batteries in the rack. This makes a total of 20.48 kWh.
