CorrectThe overkill solar product is just a relabelled "JBD" unit, right? Which apparantly is the same as this

Smart BMS 4S 60A 80A 100A 120A 12V Lifepo4 Battery Protection PCB Bluetooth APP | eBay
4S 60A 80A 100A 120A BMS:it is only BMS. Note: this BMS with balance function. 1 x BMS Lifepo4 Battery Protection PCB Board. Double star positioning: GPRS+ Beidou positioning is accurate. Bluetooth module : if you use for phone app, need to buy.www.ebay.com
JBD being an acronym for a chinese mfr.
^You get support and a warranty from Overkill
Well thats worth something but warranties are generally marketing tools used by mfrs with substandard products, which it appears the JBD BMS is not. Toyota and Honda automobiles historically have had the shortest warranties in the industry, while mfrs like Hyundai and VW, when their products were faltering, offered 10 yr bumper to bumper protection.You get support and a warranty from Overkill
Can you elaborate? Should any BMS expect to survive a short circuit?JBD BMS 120A

Fried the BMS by doing a short circuit, 15 MOSFET's gone..., bad layout, bad cooling
I don't own an Overkill BMS or a JBD BMS.Well thats worth something but warranties are generally marketing tools used by mfrs with substandard products, which it appears the JBD BMS is not. Toyota and Honda automobiles historically have had the shortest warranties in the industry, while mfrs like Hyundai and VW, when their products were faltering, offered 10 yr bumper to bumper protection.
Perhaps thats a debate I wasnt looking to start, but when I buy a product, particularly one that requires assembly so to speak, the idea I might have to box it up and ship it back for a replacement isnt expected. It could happen but if I choose wisely and research reviews it usually doesnt.
I was thinking more along availability, as their website doesnt seem to have any idea when they will have more, and if thats the case, I dont know how the warranty situation would work right now anyway.
The shipping situation from China is a real mess presently and I know thats not their fault so Im not here to attack them, just verify that what they have isnt a proprietary product.
Sorry, I am too late, I know.Can you elaborate? Should any BMS expect to survive a short circuit?
What did you do?
Or are you claiming a defect in the board caused your cells to short circuit?
