jayjay6888 Posted August 13, 2012 Report Share Posted August 13, 2012 only way to "safely" do it...(what the company recommends) is to charge no higher than 14.8-14.9 for the D3100's sake and use an external charger for the 1400 to top it off regularly since 14.8-14.9 wont top that 1400 under the hood off.. now thats just staying under manufacture specs but many people run their charge at mid to high 15's on the xs power 12v batts with no problem its just not recommended from the manufacture. cause i think 16.4v is recommended for charging the 1400's? 1 Fi Sp4 18 Crescendo 2k selenium mids audioque supertweets Hifonics for mids and and highs 1/0 power and grounds ---> on the way singer alt and possibly another 2k depending how sub likes 1 2k Link to comment Share on other sites More sharing options...
