You can get whatever (lifepo4 compatible) charger you want, and based on the system you want to run, you just need ANY (4) cells, 3.2V, prismatic (preferably), 40AH cells.
That will get you through a full day of battle at nats.
Mike has more experience with the other brands but I don't think it really matters if they are thunder sky, powersonic (batteryspace), Calb, or GBE (?).

Thundersky (yellow) cells tend to be the lightest and most durable brand. Unfortunatly, they are very difficult to get right now due to some sort of brand name litigation going on in China.
CALB (blue) cells are slightly heavier than Thundersky, slightly smaller, and has very good amp draw ratings. Downside is one thousand less cycles of life than the Thunderskys.
GBE (greenish) is the newest brand out and fall someplace in between Thundersky and CALB cells in all catagories. The 20ah cells in the Erin have perfomed well so far without any trouble other than a couple cells bloating slightly (normal for prismatic types and doesn't prevent the cell from delivering power). | | Mike Mangus

| | 07 Dec 2011 12:24 AM | | Okay, so I could use this charger for charging 2 of the CALB at 6+ volts and 20 amphr enough to run a cruiser on for 2 sorties/1 battle?

| | 07 Dec 2011 12:38 AM | | What kind of cruiser would hold two 20AH prismatic cells? You may want to look at smaller cells. For simplicity I run 6v nimh 4.5ah packs in my Gloire. | | | SMS Baden - Battle Ready

| | 07 Dec 2011 12:50 AM | | Somebody said something about blue cell and I was thinking about these, http://www.ebay.com/itm/230686164817?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 not the 20Ah square ones. Anyway would the charger work with these cells 38120S Cylinder, 2 would equal 20AH and wolud be 6.4 volts.
Right???? | | | |

| | 07 Dec 2011 07:12 AM | | Those are 10ah cells at 3.2v each. That means you would have 10ah at 6.4v with 2 cells. You would need 4 cells for 20ah. I recently bought some from http://stores.headway-headquarters.com/StoreFront.bok and had a smooth/ quick transaction. They were also very well packed for shipping. Das Butts | |

The more simple 'smart' chargers like the ones I got from Batteryspace have a built in cut-off so you have to be sure your cells can be charged to its pre-programmed cut-off. In this case it is 3.6. My yellow 20ah cells an be charged up to 3.65 so I am ok with those.

| | 26 Dec 2011 04:39 PM | | Okay Guys,
I hope every buddy had a very Merry Christmas yesterday and that you got all the toys you wanted. I got a Sigma II EQ Intelligent Battery Charger and while looking throgh the instructions I ran across a section that said Charging the "LEAD-SULPHURIC BACID"BATTERY. iS this the same as the SLA "Sealed Lead Acid Battery?
This seems like a dumb question but I just want to be sure before doing anything stuiped,
TIA, Skippy | | | |
