Re: [RCSE] Tritin Charger - how to slow charge?
Thanks for the information Jim, I was able to find the article from the members only section of the AMA website and have printed the article. Fortunately in this case they stopped scanning the magazine at the end of 2000 - so this one is definitely there. A search of the issue brought up all 7 pages.

Re: [RCSE] Tritin Charger - how to slow charge?
Russ, I worked pretty hard a couple of months ago trying to find out just the same thing. The folks at Great Planes -- Model Services confirmed what others had said, it can't be done. Sorry for the bad news. Since I really didn't need the extra capacity of the Triton I sold mine and bought an ACE R/C Digital Dual Vari-Charger at my LHS and a used Sirius Charge Pro. (By the way, the folks at Sirius told me that any of their chargers have an unlimited life time warranty, doesn't matter who owns it, original owner or not.) One draw back to the DDVC is that it doesn't have a shut off timer, but other ACE R/C chargers do. The DDVC goes as low as 5 mA so I can charge my tiny mosquito class HLG batteries. http://www.acehobby.com/acehobby/products/electronics/chargers/index.html Another option is to build the slow charger published in the AMA's Model Aviation magazine. -- Jim Holliman -- Tulsa, Oklahoma AMA TULSOAR RCSE-List facilities provided by Model Airplane News.

[RCSE] Tritin Charger - how to slow charge?
I have a new NiMH receiver pack and wanted to slow charge the pack for the first time using a Triton charger. The Triton documentation refers to slow charging but I can't seem to figure out how to set it up. I can set the charge current to a low value and set the safety timer to a large value but it seems the charger will always try for a peak detect and if it gets one then stop. The manual indicates that the safety timer comes into effect when 'peak or full charge is not detected'. Is there a way to ensure peak detection will not occur and thus get essentially a constant current charger with timer?

Peak detection is always on on the Triton. If it's in NiMH mode, there's a small amount of trickle charge after the peak is detected, but beyond that there's no place to specify a constant charge current without detecting a peak. However, you can tell it how big a peak must be before it's detected, so I guess in theory you could set that value (in milivolts/cell) as large as possible, and then it may not ever detect a peak ... But if you're looking for a constant current charger without peak detection, really, the Triton is not the right tool. Certainly, the hardware is capable of it, but the firmware just doesn't support it. Other options include using the power from a wal-wart, getting some sort of adjustable current/adjustable voltage power supply (expensive, but you may already have one), or getting a cheap charger that doesn't do peak detection at all. For the latter option, something like this is ideal -- http://www2.towerhobbies.com/cgi-bin/wti0001p?I=LXL331P=7 as it lets you pick the charge rate, and lets you do 4 packs at once. And it's cheap! -- Doug McLaren, [EMAIL PROTECTED] How are you gentlemen? RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Tritin Charger - how to slow charge?
Title: Re: [RCSE] Tritin Charger - how to slow charge? Russ, There is a setup menu option telling the charger not to peak detect for so many minutes. I doubt it can be set to 14 hours or so. Maybe.
