BillW50 Posted June 19, 2016 Author Report Share Posted June 19, 2016 The FullyMax FB900HP-3S is an 11.1V Lipo pack for use with the DNA 200. It comes with a JST-XH balance plug and 18 AWG power cables (no connector). Evolv used this battery in the DNA 200 beta mods and it performed well.Voltage: 11.1VDCCapacity: 900mAh (10Wh)FullyMax model: FB900HP-3SDimensions (mm): 19.8 x 26 x 70Max Cont.

BillW50 Posted June 19, 2016 Author Report Share Posted June 19, 2016 Wow no dedicated thread for the FullyMax FB900HP-3S? Ok I just created one.I've been experimenting with one when I recently purchased a red Hotcig DX200. They say it contains a FullyMax anyway. And once you get down to about 3.74v per cell, it starts to drop very fast. I had one about at that voltage and I put it on one of my 15 year old RC charger that charges slowly at first and takes like 10 minutes to build up to the current you set it to.Anyway I selected a 11.1v @ 2.5A lipo and pushed start. I was constantly checking for any heat during the charging and it stayed at room temperature the whole time. It finished at 12.6v and it put in 588mah in 23 minutes. Wow, impressive.Vaped it down to 3.05v per cell and I'll recharge it in the morning with a freshly brewed coffee and a nice vape. So I can keep a close eye on it and see how much it stores and how long it takes. I'll do the same to another one to check for variations. Then I'll check them through a number of cycles to see how well they perform.Stay tuned. Link to comment Share on other sites More sharing options...
dwcraig1 Posted June 19, 2016 Report Share Posted June 19, 2016 Just to keep me on track here is the 3.74 volts without load and the 3.05 volts is with load? Link to comment Share on other sites More sharing options...
BillW50 Posted June 19, 2016 Author Report Share Posted June 19, 2016 Yes that is correct. Since I had the cell cutoff at 3.05v, I had to stop since I couldn't vape anymore. It is just sitting right now.Cell 1 = 3.36vCell 2 = 3.35vCell 3 = 3.23vPack = 9.94vThat is reading it unloaded at the balance connector on the battery. But as it sits it has been creeping up a bit. I'll check it again in the morning. Link to comment Share on other sites More sharing options...
BillW50 Posted June 19, 2016 Author Report Share Posted June 19, 2016 Cell 1 = 3.41vCell 2 = 3.40vCell 3 = 3.31vPack = 10.12v Link to comment Share on other sites More sharing options...
BillW50 Posted June 19, 2016 Author Report Share Posted June 19, 2016 That low cell 3 bothered me so I charged it individually to v3.47v, discharged it some. And it settled to 3.44v. Waited 30 minutes and it stayed right there.FullyMax Pack 1Charged at 11.1v @ 2.5A10 minutes to build up to 2.5A23 minutes started dropping from 2.5A30 minutes finished charging, reported capacity is 912mah.Cell 1 = 4.20vCell 2 = 4.20vCell 3 = 4.21vPack = 12.61v Link to comment Share on other sites More sharing options...

BillW50 Posted June 21, 2016 Author Report Share Posted June 21, 2016 FullyMax Pack 1 of 3 (red)Charged with DNA200 USB 1A2.5 hours finished charging (Max Recharges 4.10v per cell)Before charging unloadedCell 1 = 3.30vCell 2 = 3.28vCell 3 = 3.12vPack = 9.68vAfter charging unloadedCell 1 = 4.10vCell 2 = 4.10vCell 3 = 4.10vPack = 12.3vIt is very clear this FullyMax Pack 1 of 2 after repeated discharging and recharging has a lower capacity cell 3 than the other two cells.

Spector NS5 RD Posted June 22, 2016 Report Share Posted June 22, 2016 could you also start including individual cell voltage readings with digital multi? to see if there are any discrepancies between how accurate the DNA reads cells compared to a meter. a good/trusted meter.

BillW50 Posted June 22, 2016 Author Report Share Posted June 22, 2016 Those readings are with one of my multimeters. I do check them with EScribe too and EScribe is the same or one insignificant digit higher. Link to comment Share on other sites More sharing options...
jurdanas Posted June 23, 2016 Report Share Posted June 23, 2016 "BillW50"All battery starts to work well after about 10 charging/discharging, this is LiPo or other Li battery.No need discharge to 3.20V all time, just one or two times with. LiPo like 4.18V - 3.70V.Then everything cope. Link to comment Share on other sites More sharing options...
BillW50 Posted June 23, 2016 Author Report Share Posted June 23, 2016 Yes indeed jurdanas. I just like to know the capacity and charging time using a different number of methods. Link to comment Share on other sites More sharing options...
