Been wanting more information when charging as a quick way to check other than turning the board on and looking at the Smart BMS info throu Bluetooth. Rather then adding some thing inline iv decided I want to build it in to a Power supply to make a nice neat package.
I don’t think the battery capacity will work as it’s not discharging thro the meter and the spec are a little confusing with both 120V and 90V, 30A and 20A listed in different places. As I’m only looking at a max of 54V 7A from the PSU should be fine.
I’m thinking of countersinking a XT60 F in to the top so I have a removable lead that’s easy to replace if it gets damaged
this was the result with I’m quite happy with it added about 23mm to the length 3mm to the depth and width but well worth it more than strong enough to throw in a bag.
if i was to redo it I would probably bezel the display in, made pockets for the PSU screws and round the front corners off with less infill as 50% its super strong (jumped on it to test)
In theory yes but I like the HLG range as it provides a much smother better quality current than all the li-ion charges iv come across and none of them cut the current so fare. I don’t see any advantage to a so called li-ion charger.
This is the largest one thay do in the range 12.5A but 50.4 is at the max rated limit of the variable voltage setting. If you jump up in to the next one it has a jump of 100mVp-p noise but still mutch better than most chargers
The 320 had a more suitable veritable voltage range and works better for my smaller packs. I recommend choosing a moddle depending on how fast you need to charge you board, slower is always better down to a point normally at 1A per cell per group
