 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I wanted a 12v battery charger with some grunt, and a powerful 12 supply was going to be useful as well so I bought a 'PowerHouse' charger as at Altronics. There are two models, one charges at 4A and one at 9-10A, I bought the 10A version and it arrived quickly. It is apparently processor controlled and give different charging profiles for standard lead-acid, AGM, cold battery, LiFePhosphate, and also a mode to act as a 12v/10A power supply. Plug into the mains, the bespoke LCD display lights up and you can then cycle through the options using the press switch on the front. There is also a battery charge state report mode which is powered by the battery itself. The AGM mode is an eye-opener, I didn't realise AGM had special requirements, and the cheap chargers often don't have the option. So far I have charged a 100AH 12V lithium iron-phosphate battery, it was pretty straightforward and charged at a healthy 10 A before tapering off. It runs fairly warm. The package has the charger, some useful cables, and an instruction booklet. The instructions are a bit hit-and-miss. One part says to connect the cables to the battery before plugging into the mains (good safety for lead-acid - prevents sparks near the battery) but other parts cite a different order. But the operation is pretty intuitive - assuming common sense ! - so it is a minor point. There are safeguards against reverse polarity and so on which is good. One of the cables has a useful blade fuse holder built-in. Watch the polarity of the connectors, it is possible to connect red to black and vice versa - not a good thing to do... errm, the fuse holder works quite well  .It is going to be really useful, especially to occasionally keep a car or auxiliary battery charged, as well as using it as good 12v source. |

Yes but it was quite a bit cheaper when I bought it |

OK Does it remember it's settings if there is a power interruption, or does it play dumb when the power is restored? ChopperP |

It remembered when I set it to LiFePhos mode, ie originally it was in PbAcid mode and I set it to LiFePhos to charge the Li battery. The next day I resumed charging the battery and the charger powered up directly in LiFePhos mode which was good. It states that it can be permanently connected, so I guess it is designed to keep the settings OK. The battery charged up fine, the current was at around 10A for quite a while and then tapered to a very low level at 14.4 v AFAIR. I then used it with a kmart "anko" inverter and some LED bar lights, for lighting in my dim garage (no power) while I changed the oil on my car. No worries ! Edited 2025-12-09 18:53 by zeitfest |
