  1. Probably cost. Finding a DC circuit breaker that can handle that massive amount of current is costly. The choice is yours, all installations I see use fused battery connections.
  2. Yes, it's still available with the fuse.
  3. I am on my way there now. I only need two but it needs to be those small round ones.
  4. Thanks. Looks like I am going to have to buy a 'hole cover' or 'plug' and then drill my own holes. Not the most elegant but it will work.
  5. Looks like I am always looking for the difficult to find stuff. To finish up my controller enclosure I need two small ventilation caps. Does anyone have ideas where I can get something similar? 25mm or 32mm would be perfect. Like what I have here:
  6. My bank also went from an easy 4H30 Load Shedding session when new to a just barely making it with very careful load management after two years - but it still made the 4H30 sessions. I did have balancers which kept the batteries in better shape than would otherwise be. My initial choice was to go the cheaper LA, but still $$$, option until such time that LiFePO4 prices came down a bit and now is a good time for that. I upgraded to LiFePO4 two months ago and very happy. In short, I fear your batteries have had it if it can't deliver on your 4H requirement. Have them checked and tested just
  7. I just did the exact same thing to my 24V garage motor backup just the other day. I replaced the two 12V 2.4AH batteries (similar size to 60mmx80mmx175mm I think) with 8S1P 32700 batteries in a staggered configuration. I bought a cheapie BMS, 20A perhaps, and it seems to work nicely. My next step is to get a BT BMS so I can monitor the cells remotely via my phone but before that I want to do a few Open|Close operations to see how many operations I can get before declaring this a success and leaving it in as a permanent replacement. My old batteries lasted 4 years (with a balance
  8. Thanks. I placed an order at Electromann, they are sortoff around the corner from me.
  9. Thanks @Gelo I see they do have them listed @ R6 each.
  10. Any idea where in RSA I can find a few of these? I need 4, no 5 x 32700 holders as I am going to break one probably.
  11. Will give them a call, thanks.
  12. Does anybody have a suggestion where I can find M4 x 8mm Hex Bolts? I need 20 only. RS has them on back order but they come in a pack of 100 and are SUPER expensive.
  13. Any recommendations for a 24V/8S LiFePo4 BMS with Temperature compensated charging/cutoff and Bluetooth connectivity? I am building a small 24V pack in the range of around 10A-20A so no large current BMS required, 20A or even 10A discharge is sufficient.
  14. Updated: The big stuff is gone, some small bits left if someone is interested.
