The alt should work work for you. The voltage is lower, because there isn't a load on it.

When are you getting the 13.8V reading? Is it a stock alternator or an aftermarket alternator?

They could start the trucks with the D375, but the 375 would not be a good option for a daily driver battery. Those trucks pull big amperage just stock. In that video the Dodge was pulling over 800amps of power on start up. That is without a aftermarket audio system. So, the 375 could start it, but you would want a battery with more reserve to use as a daily driver battery. The video was just to show the starting power of the D375, which is the smallest battery we have. That is why most diesels run two batteries. Diesels can be hard to start at some times, so if a battery has more capacity it can better handle the demands. In warm climates like Florida they can probably get by with one battery just fine. Not sure on the 550. It probably pulls a lot of power and may need a couple batteries. The D6500 is a great option for the Diesels.

Ok every time you start looking for a battery you hear people starting tell you to check and make sure it has at least **** cranking amps (CA) or **** cold cranking amps (CCA). Well those ratings were important back in the day, but these days with AGM batteries they are just outdated. The CA and CCA tests were developed back in the early 1900s. Yes, thats right those tests are coming up on their 100year anniversary. The CA and CCA test the batteries ability to put power out for 30 continuous seconds down to 7.2V. So it would be like going out to your car/truck and turning the key over to try to start your car/truck for 30 continuous seconds. If you did this you would burn your starter up. Here is the D375 rated at 190 CA starting up a 12V diesel 15 times in a row. We had to stop at 15, because the starter was getting hot. D375 Starts 12V Diesel

We haven't had them in stock, because we haven't developed them completely. We are currently working on getting a list ready to publish, but I do not have a good time frame for you. I will update as soon as we get them ready to go.

Dont for get to fuse coming off of the front battery and just before the back battery bank. If you ground in the back make sure it is a good ground with no welds close to it. Best bet will be multiple runs of 0gauge wire from positive to positive and negative to negative.

Just some random people we found when we googled XS Power Batteries. Figured they were running our decals so we might as well put them on the add...............lol

Great turn out on the registration so far!!! Remember that you have to be registered at least a month before World Finals to be eligible.

Yes you have to be running XS Power as your batteries. You can have all XS Power and an OEM battery under the hood, but not a mixture of all the batteries. This is for Team XS Power competitors. 8 points champs and 94 possible world records at finals, so the actual total payout could be over 25K.

Working on it yes, but I wouldn't expect anything very soon.

If you have no fluctuation in the charge voltage and you are running a 12V system then the VCM will not help you.

No it will not work with the 2 pin applications.

I would recommend the D5100R for upfront and then a 2 or 3 D6500 and you should be ok. 3 D1200s or 4 D925s would be the minimum to run and that is if you have enough alt power.

Depends on how much room you have to work with and if you want to run the bigger batteries or smaller batteries.

As long as you have an oval GM plug on your alternator it will work. $129.00 plus shipping.

Yours is shipping today.

We have the VCMs back in stock and ready to go with the original applications only. We currently do not have any VCMs for Ford applications.

With the 14V batteries you have to charge in the 16.8V range.

No it doesn't work for that application.

D1400s are $249 each. 1500watts each for competition and 3000watts each for daily driver applications. Do you get a check engine light now with the alts or a alt light?

Which style GM alts are you using and how did you wire it up?

For competition I would recommend 1 D1400/D1600 for every 1500watts. For daily use 1 D1400/D1600 for every 3000watts. So you would need 3 or 4 D1400/D1600 for competition use and 2 for daily use. Depends on what you plan on doing. If you are going to go 14V then I would use a D1400 as the starting battery(it would fit with little to no modification), but if you go with 12V then it looks like the D5100R would work for you. If you run 16V you will need at least 2 993 step downs.

Pyramid of power!!

Have a great July 4th weekend and be safe!!! XS Power will be closed Monday and Tuesday for the 4th holiday. If you need anything I will try to check in on the forum and help when I can. Have a great 4th!!!
