My brand new LiPo battery stopped working last night after perhaps 6 hours of operation. Though I don't recall short circuiting it (a big no-no prominently printed on the side of the battery) and I didn't see a spark, it's possible that I did as I had several wires exposed.
Now, the voltage I was measuring from the battery was fluctuating wildly beforehand and when I spoke to tech support at ExpertPower this morning he suggested that, given the fluctuating voltage and that the battery died so soon, it was likely a problem with the BMS and that I should return it. Amazon is on the case doing that now.
However, it does seem to me I was careless with the battery given that perhaps a BMS can get fried relatively easily. I'm not used to working with Lithium batteries and it seems likely that they are more fragile (due to them having electronics in the form of the BMS). My past experiences quickly crossing wires with lead acid provided a spark but the battery kept working.
So here is my question: presuming that I will take care to protect the next battery from short circuits, what are some of the fuses/breakers/magic setups that I should consider?
Other details:
• battery: 20amp•hr from ExpertPower https://www.amazon.com/gp/product/B07X523S96
• will go through this control panel after the fuse/breaker: https://www.amazon.com/gp/product/B08MQHBPBF
• expected load: perhaps just a few amps? Needs to run some LED lights and provide power to the plugs in the panel, above
• location: in a trailer likely to get really hot when traveling through the South
• it seems I want a really quick breaker or fuse to protect the BMS but this is new territory for me so I would love to hear people's thoughts!
Cheers,
André
