| 1372299 | 2014-04-09 00:26:00 | I know there are a few electricians here and this is fairly generalised anyway. If I wanted to join two batteries together to increase their voltage would I be looking for a Parallel or Serial connection. Each pack is 7.4v and I need a output of 14.8v. |

| 1372300 | 2014-04-09 01:29:00 | Simple. Connect the negative of the first battery to the positive of the second battery and then connect the positive of the first battery and the negative of the second battery to the positive and the negative of your appliance. The way of connecting the batteries as I have described is known as "in series." If you were to connect the batteries in parallel you would have twice as many amps but only have half the voltage you require. |

Also, make sure the batts are similar & both hold a good charge. You will get double the internal resistance: keep that in mind with small batts Lipos: be VERY carefull. One cell can discharge faster than the other, meaning one cell could discharge below 'safe' voltage level . If you dont have a balance charger, charge each cell separately. |

They are Lipo's but they are always balanced and I run them with a voltage alarm on each pack. So what would I need to join a couple of these packs in series to produce the voltage I need? |

| 1372304 | 2014-04-09 02:54:00 | A piece of wire? Depends on how they are connected now, if there's a plug and connector it might be a little tricky. A photo might help. If they for example had a red and black wire coming from each simply join one of the red wires to the other batteries black wire and use the other two for connecting to the load. |

| 1372305 | 2014-04-09 03:11:00 | They have EC3 connectors on them and I have adapters to changed them to T-Connectors (Deans) 5668 This is EC3 |

| 1372306 | 2014-04-09 03:52:00 | Does the single or double end connect to the Battery? If it's the dual end it's easy, just cut one red wire leaving one plug (before the other red wire tees into it) and do the same for the black on the other plug and join them together. That'll put whatever you connect to the dual end in series with respect to the other end. | dugimodo (138) | ||
| 1372307 | 2014-04-09 03:55:00 | The lead I posted was just to show you the connectors, it has nothing to do with the question. Cept it happens to be a harness to connect in Parallel. |

| 1372308 | 2014-04-09 04:07:00 | Even so, if the batteries plug into it and you modify it as I described it'll become a serial harness :) | dugimodo (138) | ||
