Hi all!
I'm a beginner trying to build a DIY 560 AH 12V battery (2P4S is my current thought) using 8x280AH cells for $1111 USD shipped to BC, Canada, from Alex at Basengroup. I spoke to Amy (who is well known on this forum) as well but it would cost $1296 USD through her and I've spoken to a few people who have recommended Alex as a reputable seller.
I'm struggling to decide which BMS to go with and would appreciate any advice! I've purchased a 3000w 12v inverter and will be using 4/0 cables, maximum load will be rarely used, but around 300 amps.
1. Daly LFP 4S 12V 400A Smart BMS with BT+ Module
- Not as keen on this one anymore due to it having internal mosfets and I've read that they are less reliable at high amperages.
- Some confusion as to whether or not this device really has low temperature protection, although Alex assured me it does have it...
2. Chargery BMS8T 600A with DCC-600HB relay
- I'm leaning towards this unit, but my main concern is that in Will's youtube the relay gets really hot. I've read that some people use a separate relay or "contactor" to keep the circuit closed if there is a fault. Can anyone share experience or resources about this and what would be the best way to set this up to have a reliable system?
3. Electrodacus Sbms0
- My main reason for staying away from the electrodacus is that it doesn't seem to be compatible with some of the components I've already purchased (Renogy MPPT)
Any help or advice is greatly appreciated!
