TAP Posted November 28, 2014 Share Posted November 28, 2014 anyone know the specs for charging IPV3 using the box as the charger? supposedly it supposed to be able to do this and has a charging input plug, but does not come with a charger..(stupid) I have a variable car charger that has changeable plugs, one of them fits. was wondering if it will safely work to charge my IPV3 here is the specs for the charging output... 3-12 volts DC/2000 mA has 3V & 4.5V & 6V & 9V & 12V settings Link to comment Share on other sites More sharing options...
Earthling789 Posted November 28, 2014 Share Posted November 28, 2014 (edited) If you have the 150W IPV3 that takes two 18650 batteries, there is no charging of the device via USB. The USB is for upgrading the chip-set ROM. *There is no charging function on this version of the iPV3* (extracted from the spec sheet) Yours may be different, but I would consult the spec sheet or instruction manual for your specific model to be certain. Given that there are two batteries, it will depend on how the circuitry are arranged, as to if you require 5V or 9V, but I would guess the minimum Amps for safety would be 1.0-1.2A, regardless? (your VV charger is 2.0A, which would work - Amps are drawn not pushed) Edited November 28, 2014 by Earthling789 Link to comment Share on other sites More sharing options...
TAP Posted November 28, 2014 Author Share Posted November 28, 2014 it does not charge from the USB, there is a separate charging port. but does not come with the charging cord...(sold separately) Link to comment Share on other sites More sharing options...

Okay, for that version (with separate charging port), the spec is a type-H connector, and I just read in a few comments... people were saying specs were 9V, type-H, @ 1.2A... but you know where that info came from (even though everything on the Internet is true :P) I saw nothing in the spec sheet for that model which said input Voltage or Amp requirements... sorry Link to comment Share on other sites More sharing options...
fishguy1123 Posted November 28, 2014 Share Posted November 28, 2014 I just watched grimmgreens vlog and he warned ppl not to use the onboard charging system. I'd do some research before you try to use it and decide if you want to or not. I think suckmymod also had some info about it. Stay safe! Link to comment Share on other sites More sharing options...

SALTLIFE Posted December 2, 2014 Share Posted December 2, 2014 The onboard charging will charge 1 battery more then the other. I bought the charger and then put the charged batteries in a efest to find 1 at 4.2 and yhe other at 4.1. Link to comment Share on other sites More sharing options...
Earthling789 Posted December 2, 2014 Share Posted December 2, 2014 (edited) The onboard charging will charge 1 battery more then the other. I bought the charger and then put the charged batteries in a efest to find 1 at 4.2 and yhe other at 4.1. Actually, it's not uncommon for two identical batteries, charged in the same charger, to read a different "charged" voltage, minutes after they are removed from the charger. Check them with a multi-meter 2-4 hours after charging and you'll see a truer reading of their charge level. Discrepancies between battery charge peak has more to do with the battery than the charger. As batteries age, or have a slightly different % of chemical make-up between the two, they will charge differently, to different levels, and discharge differently. Does it mean your battery showing 4.1V is bad? No, it could simply mean your meter is reading/rounding them differently, and actual peak voltage is 4.15 and 4.14, and it is even possible that the battery reading lower will have a higher mAh charge-capacity (last longer). The on-board charger is likely charging in parallel (since they discharge in parallel), which is the simplest/cheapest way to charge/discharge them. I've never seen the on-board charger of the IPV3, but I would suspect this is the set-up for cost-effectiveness... Reading the Voltage of a battery, hours after charging, will give you a far better picture of it's health. A battery at the end of it's life-cycle may show 4.1V as soon as it comes off the charger, but 3 or 4 hours later, it may only show 3.6V, or something else, which is far below the fully-charged level.

WillBlack Posted December 2, 2014 Share Posted December 2, 2014 The onboard charging will charge 1 battery more then the other. I bought the charger and then put the charged batteries in a efest to find 1 at 4.2 and yhe other at 4.1. Sounds quite acceptable to me. Don't you have a real multimeter? When rounding down to tenths as you did the real voltage could very well be 4.14V or 4.1 in tenths, and 4.15V or 4.2 in tenths. I also don't know why folks keep on talking about 9V 'chargers'. Tenergy (and others) has been selling 2 wire chargers for their various 7.4V (8.4V) two cell series packs for years. These chargers, rather than being simple 9V power supplies output 8.4V and will cut off when the pack reaches 8.4V. A few examples: http://www.ebay.com/itm/like/220800935948?lpid=82 They do talk about the packs having a PCB to help prevent over charging, but note: Over Charge Detection Voltage 4.35 ± 0.025V Maybe not a perfect solution, a 3wire balance charger would be better, but these 2 wire chargers have been sold and used for many years. I also scoff at Green's assertion the Sonys should be used. A few Sony 18650s in action. Link to comment Share on other sites More sharing options...
SALTLIFE Posted December 2, 2014 Share Posted December 2, 2014 ^^^ I dont use the charger for that reason. Popping the back off isnt that hard to swap out batteries. Link to comment Share on other sites More sharing options...
