12V 225Ah Deep Cycle Lifepo4 Lithium Battery with Bluetooth Environmental-friendly
1. About us
Shenzhen Topband Battery Co., Ltd, a company professional to do LiFePO4 battery, which is founded in 1996 and listed in Shenzhen in 2007. There are over 300 R&D engineers and about 3,000 employees in the 70,000 square meters Topband industrial park. We can provide One -Stop Solution of new energy, from cell, BMS/PCM to battery pack assembling.
This rechargeable LiFePO4 battery pack TB12225F-S108A support Bluetooth communication function. Through Android and IOS APP, can read the battery status and information. Especially due to the Android system’s openness, different smart phone manufacturer will have their own different Bluetooth hardware version and customized feature Android systems. It is necessary for the customer to confirm whether the phone is compatible for the APP.
