Steve said: 156 Pounds.... I drool over those weights, my AGMs (900 Ah ) 2v cells weigh that much and a bit more...
Waiting to see how they perform at startup and after 1 yr. They truly may be good value for money spent.
When I first went to lift the LifePO pack my back immediately remembered the manhandling of the Rolls Batteries which are 120 lbs a pop, X8... ugh.
Excellent! Looks just like what I have. It looks like you even have a bigger charger, 50A. The charger I received only does 30A.
It would be nice if those are 200AH cells in there.
I let the pack sit because it arrived and was extremely cold and I felt it best to let it fully warm up / thaw out thoroughly before dong anything. The two charger's are mounted to a single aluminium plate (thing was wrapped in 20' of stretchy plastic... geez) I noted that I got 50A and you got 30A, how odd. I had asked if they would make it with a 150A bms rather than 100A but that was after I placed the order and don't know if they did or not.
UGH ! Something I really don't like
-
No Documentation of any sort included. no specs, no details, built sheet, nothing. No info on the charger(s) either. No company or warranty info.
- The BMS is mounted in such a way, that the NEG Lug on it stands proud, with the lid on, it puts some strain / pressure on the PCB (never a good thing) causing it to push down a bit. They KNEW THIS and their solution was to put a lot of "white goop" over the lug and then cover over it with a double piece of that fiberglass(?) insulator.
-- SERIOUSLY, How hard would it be to toss in a Photocopy of a spec sheet, charge profile info and when filling out the assembly label (only item on it) could put what the BMS Amperage is etc...
Couple of things I like right off:
- Case is Stainless Steel, strong & durable, well made, solid handles (thank goodness at 71kg they got to be).
- Everything is well secured & glued down / fixed to prevent any movement, even all the connectors are sealed in.
---- CON, lot's of glue & sealant, not very 'tidy' but that's just minor.... all wires & connections seems to be very well secured though, something that not all companies do, actually. (thinking of Will's recent tear downs (not the battleborn - they are awesome IMO)
- The Cells and assembly is quite snug but not overly tight and there is isolator sheeting (fiberglass(?)) on all sides internally around the cells.
@Delta-V I have to ask, did you come up with any trick to soften up that white glue sealant stuff ? Seems they also used some kind of epoxy in a few places as well, I don't want to break anything as I want to "gently" take it apart to examine it. Also I no longer have any of my testing equipment & tools I used to for electronics works (was all destroyed) so I am limited to what I can do to test the pack. I would rather test this "outside" of my running solar system before I incorporate it, which creates a few other issues as I want to keep the FLA side (bank-1) going for as long as I can... that may be another thread I think. Suggestions on load testing etc it simply would be helpful, all I have a decent DVOM. no extra funds to buy a pile of gear either.
EDIT: 09:30 hrs
I have been searching for info on the Charger setup. While it looks like a Meanwell (many do) it's labelled as "LED Power S600-12" and the only other label has Kejian" on it but everything else is in Chinese on that so.... I can't find "LED Power or Kejian" using google or duckduckgo so I dunno what to think about that, other than being a tad unimpressed.
