Thank you for your following! Our 12V 100Ah MINI will be delivered to the US warehouse at the end of September.

Welcome to join our beta testing program! We’ll demonstrate the latest upgrade of the WattCycle App — now supporting synchronized and stable discharge across multiple batteries in para...

@TWesthoff wow.  That sounds weird. it does make one wonder if relying on the BMS to stop charging is a good idea or not. I've read of many that are using the internal BMS to stop chargi...

@KevenLikeSeven, as a spare Start battery, it'll probably work, but it would be wise to compare the loads pulled by the starter vs the battery's CCA. Used regularly for Start, I'm sure that LFP wou...

@Rascally It seems that what the BMS does to protect the cells from over voltage, by shutting off Charging had an unintentional bug that somehow disabled Discharge while leaving the Discharge indic...

@gloftin48 Yes, you are describing the problem exactly. The "test" phone app they released yesterday seems to work. They made a video describing it, and the link to the "test" phone app is above in...

I bought this one. It won't be my primary starting battery but I wanted it to have start capabilities in case of emergency:   https://www.wattcycle.com/products/wattcycle-12v-100ah-1200cca-m...

@KevenLikeSeven, also... is this lithium battery is your starter battery?  If so, you'll probably kill the battery. It may not be big enough.  Have you verified the load required to star...

@KevenLikeSeven lol.  About your question... if your lithium battery is charged by your alternator, you'll need to protect the alternator from two things, 1) overheating due to tremendously lo...

The app needs a password protection! Anyone can mess with my battery when I am travelling, this is dangerous.

@TWesthoff , can you explain how preventing discharge (disabling discharge (sometimes) when it's detected that another battery is connected in parallel) would protect cells from over-voltage?  ...

@Rascally I was gonna say, I'm new to Lifpo4 but not that new......your answer made me think  I was in over my head!

@Rascally I think it was to protect the cells in the battery from over voltage. It does do that, but there was a side effect which it appears is fixed with the new September 3 version of the Androi...

@gloftin48 , offering a replacement might be more about trying to offer good customer service than an indication that replacement is necessary. Of course, you could be right, but hopefully not.&nbs...

The download I have been sent from Watt is to large to down load. It doesn't work.

I have the same issue using 2 x of the new 314 ah "smart" batteries in parallel. Sent a note to support and they offered to replace the batteries which tells me there is no firmware update availabl...

Your question is about how to ensure parallel discharge works as one would expect it to work. Does anyone know what the manufacturer was trying to accomplish with this strange behaviour that prev...

Your question is about how to make parallel discharge work as one would expect it to work.  But does anyone know what the manufacturer was trying to accomplish with this strange behaviour that...

I heard that there is an update too.  I've tested my two 314 mini BT and the first battery in the string stays 90-100% while the second battery will drop to 40ish % before the first battery as...
