ORIGINAL: BCer-RCer

The instructions for programming Li-Po state "" In this menu the nominal voltage of the battery to be connected for charging and discharging can be set using the INC and DEC buttons. Possible values are 3.7V, 7.4V, 11.1V, 14.8V and 18.5V."
If I were to have the setting at 11.1V, but only have a 2 cell Li-Po connected, would the charger auto detect the 2 cell pack, and not attempt to charge it as a 3 cell (11.1V) pack?
I tested your question with a charged two cell Li-Po and found that the battery attempted to charge for a minute or so at a very low rate (,20) and then the charger honked, buzzed and said LOW VOLTAGE error while shutting down! So I guess it’s safe to assume it recognizes it’s not a three cell battery by virtue of the cells voltage, the inverse is true as well charging a three cell pack with two cell parameters.

Regarding charging at 0.7C ( which for a TP 2100 ma pack would be 1470 ma I believe )
Lets say you have a 1000 ma capacity pack and want to charge it at 0.7C You're saying to input 700ma as its capacity. Does the charger not stop the charge at 700ma? This would mean having to restart the charger to get a full charge. Would this work OK?
The capacity rating dictates the charge rate and the charge passed to the battery. I tested by setting up a 2000mAh Li-Po at 200mAh capacity, been charging this evening now for 66 minutes at .20 once the battery adsorbed 220mA the charge terminated. I don’t see a problem with sequencing multiple charges to reach full charge at low charge rates.


1C is the maximum charge rate, so I'm thinking that charging at less than maximum might increase the life span of the packs. Don't think I'm alone on that thought. At home I'm in no rush, so why not charge at a lesser rate.
There is NO doubt that charging at lower rates extends battery life. It’s well known IMO.

How reliable and accurate is the peak detection when slow charging a NiMH Tx or Rx pack ? Thx

MoJoe,

Do you have / have you tried other chargers? Especially the Triton?

I think that a few people in here (including me) are hesitating between a Triton and a LN5014. I've got a LN-5014 on order, but could still switch for a triton..

hi marty.... this is my first "real" charger....

having the option, i probably would pay the extra $30-$40 for a triton or a Duratrax Ice .... just coz of their extra features that i listed above that the 5014 doesn't have.... especially now that i am going from Nitro to Electric racing...

I've used the LN- 5014 for a few weeks now. My application is primarily e-flight. I have a full featured charger (with memories) that is my primary field charger. However, I have found myself using the Multiplex more often. I'm not sure if that is because it is newer or easier to use. I would consider this to be a niche charger; a major step-up from beginner e-flight chargers like Hitec CG340 or Multiplex LN2010 without the extra expense of a Triton. However, the LN-5014 offers a good deal of flexibility and user friendliness without some of the extras found in the Triton. Multiplex seems to have kept the essentials of a solid e-flight field charger while eliminating the features that drive cost higher.

THanks for the info guys.

I've got a glow helicopter but might go electric some day (t-rex, or something small). Would I miss something by not going to the Triton? The last thing I want is to find out there's a feature that I need but is only available on the Triton. I'll spend the extra $$$ to go for the Triton if it's a better charger.

Mart242,

It's not worth loosing sleep over if you don't mind spending the extra $$$. Get the Triton. However, I believe the LN5014 is a great lower cost alternative. Personally, the only feature that I will miss is higher discharge rate for cycling. However, my e-flight packs get a lot of "cycling" in use.

The only time that I have had the problem that you describe is when the battery pack had a problem. Also, when charging a pack for the very first time, make sure that you charge it at the overnight rate. For your 1800 pack that would be 180ma, 10 hour charge. A lot of guys at our field getting into E-flight for the first time swear that their charger is bad because it false peaks on a brand new pack. I have found that some cells, specifically those with higher internal resistance (AAA nimh) definately can not be charged at high rate for the first time without false peaking.

My Triton is on it's way. It's proven, so I might has well play it safe. Most heli flyers around here have Tritons as well.

Mart242,

That sounds like a wise decision. You will have a good pool of heli flyers to help answer questions regarding your Triton.

also i found in cycle mode, the user cannot secify the volatge with which to stop discharging.

i set it to 1.1 per cell on the discharge screen, however when i put it in cycle mode it goes below 1.1 per cell... i'm not sure what it goes down to... coz i stoped the discharge before i found out....

The triton seems to be preset as well on the cycle mode. I have a question on this charger compared to the triton. Does it constant charge? or does it stop every minute like the triton?

That is one of my main dislikes about the triton. It brings the effective charge rate down to 4.5 instead of 5 really.

thanks, I do have the ice and is very good. I wish it would do more than 10 cells.

ok i have just used this charger a bit more.... i have been trying to charge 1800mah aa batteries... i charge 4 peice cradle... i charge at 1.5mah, and it charges for about 4 minutes, puts in about 140mA then stops... i try to chrage again and it stop again after 4 more minutes... it thinks its full and is just peaking it...

I am not sure what the hell is wrong... i now really wish i bought a Duratrac Ice!!!!

i have updated my review above [>:]

It's not the charger!!! I'll bet this is a NIMH battery? The charger is a Peak charger, the voltage peaks the charger senses this and shuts off, simple. You need to cycle NiMH several times to bring them up to capacity. Simply run at least three cycles and note the capacity after the last discharge cycle.

You also might check your leads.
The Hobbico ones are 2 long and 2 thin to be much use and cause many a false reading.
Ive been useing this charger for a year now and it works well minus the memories etc as noted, With discounts the Triton is only a little more.
I have had false peaks from a Schultze, Triton, Ice etc etc they all will do it given the right circumstances.

If you look back thru the forums titled best value charger there was I think 3 other chargers all the same Multiplex just put their logo on it I posted a pictur of mine.
Dymond is one of them.

for what application do you require to charge more than 10cells at once?

thx
