WattCycle 12V 100Ah Mini LiFePO4 Battery for RVs and Trolling Motors

Like the battery but failed capacity test

I love the form factor of this battery but unfortunately it failed three capacity tests. Customer service has been great but it still failed. Not by much but was below 100ah

Bluetooth version of 100 amp hour Mini: almost perfect!

Only reason it doesn't get five stars from me is I have an older Android 7 phone (Nexus 6) which is not supported by the BMS Meta app. I was able to get it working on a Kindle fire 7" by using a free app called Fake GPS. This was only possible after "jailbreaking" the Kindle and enabling google play store (a technical process which is difficult for many). If you have an obsolete phone this may be an issue for you and I did not feel like I should have to purchase a whole new phone just to watch the battery's behavior. I purchased after watching teardown videos on youtube to confirm build quality and safety features. Really, this is a five star battery for anyone not using an obsolete phone. After a few weeks, I liked it enough to buy a second unit and hooked them up in parallel for 200 amp hours.

Works great, good price, and the compact size is perfect for mounting in my boat.
