| Proper balancing multi-cell Li* BMS |
| (1/1) |
| paulca:
Has anyone found a working BMS that supports multi-cell balance charging of Lithium Ion/Polymer, protection and charge/discharge control with inline load? It seems very difficult to find something that works and most of the current BMSs either work only for single cells or don't balance charge. |

Or? I'd suggest that single-cell BMS's don't balance charge either. There's nothing to balance. |

Are you suggesting limiting everything to single cell and parallel cells at 3.7V and using single cell BMS boards? Seem a bit limited. If you need roughly 12V using a 3.7V and boost converter doesn't sound efficient. |

I'm going to try this one. The IC used has 70mA of internal balancing. Fully open, with source code for the atmel CPU. https://www.tindie.com/products/ceech/18v-20a-lipo-li-ion-battery-management-system-bms/ |
