fiore Posted July 14, 2015 Report Share Posted July 14, 2015 I am hoping that someone here might have an answer for me and yes i have used the search bar. I've just purchased a Globalmediapro Li75N Lithium ion Battery to power my rig, previously i've been using Ni-Cads and decided to make the jump to Lithium. now that i received the battery it charges (on their designated charger) with the battery check light confirming a full charge yet when i plug it into my BDS (with nothing attached to it) it doesn't power on. also when testing the battery with a voltage meter i'm getting a reading of 0.0 I'm thinking that the battery might just be a lemon but i'd like to exhaust all options.

Glen Deakin Posted July 14, 2015 Report Share Posted July 14, 2015 That doesn't sound good. either the batter may be bad or could even be a bad charger. Did you try charging a second battery with it? Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 Haven't tried charging a second battery, I plan on testing it in a few days on a buddy's bds. I don't think the charger is the issue. unfortunately after about 15 emails with gmp the response I got is "Please only use our battery with compatible equipment. Before using itwith any other equipment please email us for compatibility advice.Please do NOT use our battery with the distribution system (BDS). Theequipment you mentioned is NOT compatible with this battery." Quote Link to comment Share on other sites More sharing options...
Glen Deakin Posted July 14, 2015 Report Share Posted July 14, 2015 That seems like a weird response. Try charging the second battery. Quote Link to comment Share on other sites More sharing options...
resonate Posted July 14, 2015 Report Share Posted July 14, 2015 (edited) I use a pair of GlobalMedia Li65N's with SWIT charger (and a Hawkwoods BDS) for a couple of years now. Zero problems. Edited July 14, 2015 by resonate Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 Resonate what do you power on a single battery and what mixer because now I'm being told that this battery cannot power a 664 or rather I was told - this battery doesn't function on a bds system - the battery's output is not enough to power a 664 - I've overloaded the battery by only pluging it into my bds (with nothing attached) im trying to think of a word to describe beyond frustrated Quote Link to comment Share on other sites More sharing options...
Glen Deakin Posted July 14, 2015 Report Share Posted July 14, 2015 (edited) I'm assuming you used the BDS system previously with a different battery so you know it works correct. Seriously just try charging the second battery then before putting it on the BDS check its voltage and see what it says Edited July 14, 2015 by Glen Deakin Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 I don't have another lithium ion battery at the moment to test it with but I'll be seeing a friend on Thursday to test it out. on the part of gmp they've washed their hands of the situation saying that I've misused the product by simply plugging it into a bds.

Glen Deakin Posted July 14, 2015 Report Share Posted July 14, 2015 Question did you get the batteries right from them or did you purchased from a dealer? Quote Link to comment Share on other sites More sharing options...
resonate Posted July 14, 2015 Report Share Posted July 14, 2015 I don't have another lithium ion battery at the moment to test it with but I'll be seeing a friend on Thursday to test it out. on the part of gmp they've washed their hands of the situation saying that I've misused the product by simply plugging it into a bds. That is a very weird response - how can that happen? battery distribution system just takes the power from the battery, regulates voltage, and distributes it to various outputs...... I would think that something is wrong with the battery - it looks a lot like mine, the voltage is the same...14.8v, your battery has more capacity, that's the only difference i notice. I've been powering tascam dr680 and sd442 of that battery for a long time, and now use it with Nomad, i always connected the direct out cable (full voltage) to the sd442 (now Nomad), and then used the regulated 12v of Hawkwoods shoe to power the rest of the kit. I think it's a lemon? this is a charger i use - never had problems - got it from pinknoise along with the batteries :http://www.pinknoise-systems.co.uk/swit-sc302-np-1-2-way-charger.html Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 I purchased it directly from them. this whole ordeal has left a sour taste in my mouth. they've told me that I've misused the product and that there will be no exchange seeing as a bds and a sound devices 664 are not part of their approved equipment . Money lost and lesson learned. Quote Link to comment Share on other sites More sharing options...

resonate Posted July 14, 2015 Report Share Posted July 14, 2015 what bds do you use? Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 I tested it with two separate units. A remote audio v3 and a home made jobber which I use for emergencies and odd situations. both work flawlessly with older ni-cads and idx npl7s' Quote Link to comment Share on other sites More sharing options...
SYsounds Posted July 14, 2015 Report Share Posted July 14, 2015 Did the battery die as soon as you plugged it in or after switching on the 664 to ext.? This is what I must do with my gmp batts. Have everything in the bag off, plug in the np. Switch the 664 to int batt let it start up and then switch to ext. after that turn on everything else that's plugged in. Someone explained to me before why it automatically fails when switched directly to ext but I now forget the reason. ..get what you pay for Though it's a weird tweak my 3 4yr old gmp np1s are still running fine and power my 664 411s SRB and ifb just fine.

Soundwil Posted July 14, 2015 Report Share Posted July 14, 2015 I've had this situation before with other types of Lithium - Hawk-Woods. What I think happens is that the start up sequence of the 664 draws too much power just for the first milliseconds (or something) and the protection circuit within the battery kicks in. I've found that initially powering the 664 from internal batteries just for the first few seconds and then switching to the lithium will not trip the battery's protection. This only happens with freshly charged Lithiums. Hope that's what up with yours. ..... or what Jordan says! Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 Thanks for the Advice guys I'll give it a shot when I get home later. thing is that the bds isn't powering on at all with the battery plugged into it with nothing attached.

Maybe the battery has stayed in its protection state, I think sticking it into the charger for a kick start should bring it back to life ...... maybe. My experience was that the batteries would come back to life eventually on their own (10 mins?). Please take my observation and speculation as just that - your problem may or may not be totally different. Quote Link to comment Share on other sites More sharing options...

nevo Posted July 14, 2015 Report Share Posted July 14, 2015 I have many GMP LIONs and had a problem recently with their 75mwh np1 and the battery protection circuit..... I have two chargers the 2 bay one and their single charger.the single charger i bought had a dtap male plug on it and a female adapter cable.... The plug will fit both ways and there is no indication of which is positive /negative..... The battery circuit protection kicked in and the battery didnt output.I put the battery in my 2 bay charger and it it came back to life.....The company were a pain in the arse to deal with I have used their batteries/chargers for many years and this was the first time ive had any issues Try resetting the battery by using another charger or wait a few days and it should reset Ant Quote Link to comment Share on other sites More sharing options...
fiore Posted July 14, 2015 Author Report Share Posted July 14, 2015 I'm going to give it a couple of days and see, thank you all. Your help has been much appreciated and very informative. Unlike global media pro customer service 😩 Quote Link to comment Share on other sites More sharing options...
Cedric Akins Posted August 14, 2016 Report Share Posted August 14, 2016 Any news as to haw this worked out. Unfortunately I had a similar issue. However I know why my battery stopped working. I accidentally touched my bds supply chord to the metal body of my mixer. I saw a small spark. The battery stopped working immediately. I tried a different battery and the equipment powers on properly. The defective battery shows a full charge but does not power anything on. Does anyone know how to reset a li-ion battery , if that is even possible? Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted August 14, 2016 Report Share Posted August 14, 2016 What make battery, could be a breaker or internal fuse. Quote Link to comment Share on other sites More sharing options...
Cedric Akins Posted August 14, 2016 Report Share Posted August 14, 2016 It looks like GMP, but there is honestly no brand on it. I just found a name by Beillen when it say only Charge with a specific charger. Quote Link to comment Share on other sites More sharing options...
