| 1415139 | 2016-01-27 22:59:00 | Anyone actually use one or own one? i have just found out about them. I want to resurrect some of my rechargeable drills, that have dead batteries. I have converted one to run from a 12 V car battery/jump starter), buy gutting the dud batteries from my Hitachi 9.6 V drill , and poked (drilled) alligator leads through the battery housing and clipped them to the +/_ metal tags. Runs good. But only semi-portable. So another and perhaps more universal approach, as I have discovered (YouTube) is to use RC LiPo battery packs (e.g. 11.2 or 9.6 V packs (goo.gl)), used by hobbyists for model cars, with a balance charger. This seems easier than bothering to tack solder sub C's... just quickly attach RC packs and balance (e.g. with Supermate DC 6 (goo.gl) or the iMax B6 LiPo (goo.gl)- from google Images) charge them. But wondering if benefits outweigh any pitfalls, or to use the much cheaper universal chargers. |

Search youtube for lipo fires, and then rethink if thats what you really want to bodge into that batt pack. lipos have burnt down houses, the flames are really nasty & are very hard to put out (use sand) Also, lipos are voltage sensitive. Overdischarge them & they will be ruined . Home workshop tools using lithium based batt packs need to have battery monitoring electronics built in, to stop overcharge & overdischarge. RC LIFE batts are much safer than LIPO, but less common. In other words , a very bad idea . :-) fire death burn . |

Because...4 different manufacturer/battery placement (internal and external clip ons) drills.One or two packs will fit them all, as I seen in a video. Also kind of experimental, as i am looking for alternatives RC battery charge set ups...for universal use. Plus all less than 12 V (for light drilling), but if 18 V or higher and if used frequently then maybe a aftermarket fitting battery. Also I have about 6 power and hammer drills as backups... |

If anyone here operates model cars, boats, helicopter, planes, trains, drones, must be using some kind of universal or balance charger. Or are specific battery packs used? |

| 1415146 | 2016-01-29 02:09:00 | Throw the lot away & buy yourself a new one from the warehouse. +1 except not the warehouse, buy a decent brand and it'll last for years. My old 7.2v makita drill and battery outlasted half a dozen replacements that were cheaper, still works now even though I rarely use it any more. Somewhere I still have a ryobi I was given for my 21st and never threw away but a new battery is worth more than a new drill is. |

If anyone here operates model cars, boats, helicopter, planes, trains, drones, must be using some kind of universal or balance charger . Or are specific battery packs used? RC cars & planes use lipo, the dangerous batt :) Most serious RC guys have good balance chargers, & store lipos in steel toolcases, charge the lipos in fire retardant lipo bags . Most lipos (99 . 9%) dont catch fire, but you only need one, and the only way to put it out is to smother it (sand) . The toy grade stuff , toy helis & planes have toy grade chargers . Thats an accident waiting to happen , a mate tried one of the toy grade chargers , he said it put the batt way over safe voltage . A couple of NZ RC guys have had nasty suspicious fires, burnt down a garage & a business, but they never say its the lipo . Perhaps thats for insurance purposes . :) In Aus, a small suitcase full RC gear & lipos caught fire , luckily while the plane was on the ground . :eek: Imagine if that happened while airborne . abc . net . au/news/2014-09-08/undeclared-batteries-sparked-plane-fire-at-melbourne-airport3a/5728574" target="_blank">www . abc . net . au |

There was one here in Nelson, actually Stoke. From what I recall the entire house was destroyed with neighbouring properties at risk for a while |
