All advice and info welcome! Skiprat - that is cheating! :poke: lol, only kidding you, seems an easier solution. John Rudd - I`m also going to have a bash at building the one in the link (http://shdesigns.org/gcellchg.html). I`ve just ordered the LM317T volt regs as it is something I don`t have in. Just purchased now off ebay so should be with me shortly. I`ll let you know how it goes! HS93 - thanks for the advice but I fancy having a go at making the charger unit, I like building things :) |

get a cigaret light plug and plug it in the car no problem couple little drives and its charged :D was thinking you could use one of those jump boxs as wel that would work well and its all self contained |

have a look at the kiys on the link sometimes it works out as cheap to buy a kit than get the bits individualy plus you get a circuit board. http://www.quasarelectronics.com/smart-kit/1095-lead-acid-battery-trickle-charger.htm http://www.quasarelectronics.com/batteries-chargers.htm#Battery-Chargers Peter |

Chris, Here is a battery charger/power supply I posted back in January. The circuit uses two LM317's so you can not only pick the voltage but you can also limit the current available to the load. I made several back in the late 80's for myself and friends. I have used mine frequently for over 20 years and have never had a problem with it. I am currently charging a Lithium Ion battery in a cordless drill that came to me without a charger. All the components are mounted on tie strips and no circuit board is required. http://madmodder.net/index.php?topic=2551.0 Joe |

Well I am having some probs with this build,the output voltage is max 8.8v.. Instructions say adjust the pot for 13.4v output but it just won't go high enough! I may very well build yours as well joe but for now going to get the one in johns link working! Any ideas guys?!? |
