Re: Roypow Lithium Review
I have built processor controlled battery dischargers for smaller battery packs but none large enough to do my Leaf modules. Unless you do them one at a time, the power dissipated is quite high even at fairly low amperage. I have an accurate speedometer / odometer on my carts so I keep track of how far I drive between charges and what the SOC is when I charge. From that I know that my batteries are performing about the same as when I got them.
I really like the Leaf modules of old but any of them that you get now are likely to be severely degraded and are probably not worth what folks are selling them for. When I got mine from Hybrid Auto back in 2016, things were different. |

Re: Roypow Lithium Review
I did one module at a time, not the entire pack. For the entire pack I would use my SOC meter and pull a fairly constant load using a 48v inverter connected to an electric heater, say 1200w or so. That would draw about 25A allowing for losses.
The 40A unit I described above can only do one cell at a time, either 3.65v LiFePO4 or 4.2v NMC. |

Re: Roypow Lithium Review
Are you still happy with RoyPow? I am looking at a 48v for my TXT.

Re: Roypow Lithium Review
I'm very happy, wish I had done it before. Spent too much time worrying about if extra cost was worth it. Will not buy FLA's anymore.
