YinLong Lithium Cells FAQ

YinLong Lithium

This is a re-share on a write up previously made regarding these cells. With yinlong cells being so popular I figured it was worth a share again.

1. What can each bank handle?
Each bank is rated for 4,000 watts on music. *All ratings are made with no input amperage*

2. What does each “bank” consist of?
6 cells in series equals 1 12v bank. Each bank can be charged from 13.8 to 16.1 safely.

3. What should I charge these to?
We suggest you running these lithiums at 16.0 or less. Any higher will reduce lifespan.

4. Do I need a balancer for my bank?
I definitely recommend a balancer. However, I break my banks apart every 3 months and let them sit in parallel over a day or 2 to balance back out and do not use a balancer.

5. Can I run these with other batteries?
We suggest running Yinglong without any agms or lead acid batteries installed in line. Agms or other conventional type batteries tend to pull down the lithium and will reduce its output.

6. What type of size and wire should I use with a bank of Yinglongs?
We suggest Atleast 1 2/0 OFC ground correctly installed from this bank to a suitable ground location. More than that is always preferred. CCA wire is not recommended.

7. How do I charge this bank?
We recommend charging your lithium battery with a correct lithium charger. However, many charge these with a regular charger and have no issues.

8. Can I run a bank of Yinglongs with other lithium battieres?
We do not suggest mixing lithium chemistries.

9. Do Yinglong banks run fine with ultracaps?
Yes. Yinglongs run amazing with ultracaps, we’ve tested it and it’s beautiful.

10. When should I balance my yinglong cells?
We recommend balancing before assembly. If not using a balancer, break them apart periodically to balance them all in parallel. However, a active balancer is much easier.

11. How do I connect these cells together to make a bank?
1/4” thick links or thicker are recommended for straps between cells.

12. What are the specs of these Yinglong banks?
These are rated for 10c continuous. 30,000 rate cycle life.

13. What type of battery is this?
Yinglongs are Lithium Titanite, They accept charge much faster than other lithiums on the market, and are extremely safe.

14. Can I run these under the hood?
We do not recommend you run these under the hood, as they do not like heat.

15. Do these like being cold like my AGMs?
No. Lithium actually does not perform as well in the cold. It has to do with the anode and the cathode and how they pass through. They will perform fine in it, just not as strong as they would in 50+ weather.

16. Can these replace a normal car battery?
Yes, these can replace a normal car battery and can start a car no problem.

17. What type of wire should I use with them?
We recommend 1/0 cable minimum. The more the better.

18. How do these make a battery?
6 cells wired in series (each cell having a 2.3 nominal charge) equals 13.8. Once in series, you will have a + on one side and a – on the other end. If the cells are fully charged and they are assembled correctly, you should see around 13.8 resting.

JsAlternators High Output Alternator Installation Instructions

JS Alternators Testimonials

Installation Instructions

REQUIRED Installation Steps:
(Wear eye protection, remove jewelry/loose items, allow car to fully cool before starting installation)

Batteries must be fully charged before installation.
Make sure vehicle is off and engine is cool.
Disconnect the negative cable from the battery/batteries.
Disconnect all other wiring from the alternator.
Remove the belt (note the belt routing before removing).
Remove the bracket bolts and original alternator.
Mount the new alternator. In general, the original bolts will be used.
Inspect the belt and replace if there are any signs of wear. We suggest you replace the belt with a .5 to 1-inch shorter belt when installing a high output alternator. Install the belt. Make sure routing is correct and the belt is aligned to all pulley grooves.

Connections Of Frame/Body: Clean all metal surface of any paint or rust with a wire brush or die grinder. Use a conductive corrosion inhibitor available at any electrical parts supply store.

Grounding (Uni-body frame warning): Many newer vehicles have “uni-body” or sheet metal frame structures with no traditional “full frame”. Because of seams and adhesive attached body components, additional steps may be required for proper chassis grounding. Choose the location on the sub-frame with the thickest metal possible. If there is lower than spec charging voltage at the battery, move ground connections or add additional ground cables to different frame components.

*** WARNING ***
Keep all electrical wiring at least 12” away from heat sources to avoid fire of the cables jacket!

There are THREE Regulator styles. Read each to determine which one your alternator has and read it’s side-note:

Factory Plug:
Be sure factory plug is clear of all debris and fully snapped into place in regulator.

Turn On Single Wire Alternators:

Follow this step ONLY if we shipped a pigtail plug with your alternator. You need to connect the (L) excite wire to L/IG on factory plug or to a 12volt switched ignition power source and connect sense wire (S) directly to positive post on alternator.

Self Excite Alternators:
Self-exciting or better known as “one wire” alternators will have NO plug on the alternator, and the OEM alternator harness plug will be left disconnected. This type of alternator requires only the positive and negative battery cables to be connected to the alternator to function. These alternators are internally regulated and will turn themselves on and off with engines rotation and regulate their own charging voltage. (May cause battery light to cut on).

It is highly recommended you add a dash mounted volt gauge.

Connect the battery ground and confirm all other electrical connections are complete.
Confirm the belt path is correct and clear of obstacles.
Before starting the vehicle, check and confirm that the battery is charged.
Starting the vehicle with a discharged battery can damage the alternator.
Use a battery charger to charge the battery first if voltages are not adequate.

Ground Path Resistance Test
If resistance is greater than 0.1V confirm the following:
Confirm all paint, anodizing, rust removed, and the connections are to bare metal.
Make certain all terminals are tight to the wire.
Make certain the ground wire is of proper size.

Charge Path Resistance Test
If resistance is greater than 0.1V confirm the following:
Alternator charge post nut is tight.
Make sure charge wire is proper size.
Battery Recommendation

2000 watts: upgrade main battery, 1 rear battery
3500 watts: upgrade main battery, 1-2 rear batteries
5000 watts: upgrade main battery, 2-3 rear batteries
7500 watts: upgrade main battery, 3-4 rear batteries – 2 alternators
10,000 watts: upgrade main battery, 3-5 rear batteries – 2 alternators

Honda ELD Dual Mode High Output Alternator Charging System Explained

Honda uses a dual-mode charging system on most 1990-2012 applications (figure 3). This system decreases drag on the engine while cranking and reduces charging system output (engine load) for improved fuel economy. Similar to other systems, the PCM controls the alternator. The PCM receives the system voltage and amperage demand from the electronic load detector in the fusebox.

Cranking (Low Output Mode) — during cranking, the PCM will set the output target between 12.4-12.9 volts. This mode will be active when the system meets a given set of criteria, leading the PCM to command the alternator to reduce the charging system output. Don’t misinterpret low output mode as a bad alternator.

Normal Mode — with the engine running and a specific set of criteria met, the PCM will command a target output voltage between 13.5 and 14.9 volts. With the ignition switch on, the alternator should receive a signal on the IG circuit greater than 12 volts, which it uses to activate the alternator.

GM RVC 2pin High Output Alternators Explained

GM RVC Regulators Explained:
The GM regulated voltage control system can vary from 11.5 –15.5 volts. As with other systems in use today, the GM system has a fuel economy mode, which is designed to lower the charging system voltage by reducing the alternator field strength.

Technicians often diagnose this mode as a faulty charging system, only to find out that the vehicle operates the same even with new parts installed. Simply applying maximum load to the vehicle’s electrical system will cause the PCM/ECM to respond, raising charging system voltage.

GM also designed this system to identify battery sulfation. In response, the PCM/ECM will command the charging system’s voltages to increase to as high as 15.5 volts, even when there’s no electrical load. Sulfation mode will typically last less than five minutes at a time, so, as the timer expires, the system will return to normal charging operation.

The BCM is the brains of the operation, but the PCM is the module that actually controls charging system operation. The PCM controls the signal to terminal L of the alternator to control system output.

How to Choose an Alternator: Can High Output Alternators Cause Damage?

JS Alternators High Output Alternator

When you upgrade your car audio, it’s important to consider the extra power requirements that come along with a beefed-up sound system. Your factory alternator may be enough, or it might not cut it. The question usually isn’t if you need a stronger alternator, but how much bigger it needs to be, and how much is too much.

How Much Alternator Is Too Much?
The good news is that replacing a factory alternator with a high output alternator, in and of itself, isn’t going to damage the rest of the electronics in your car, even if the new alternator is much, much bigger than the old one.

As an example that trends closer to the ridiculous than the likely, let’s say that you determine that your new sound system, plus the preexisting power requirements of your car, add up to well over 200A. For a safety net, you decide on a 300A alternator.

Should I Upgrade My Alternator?

2009 - 2010 Ford Mustang High Amp Output Alternator

What Does the Alternator Do?
Alternator Basics:

Alternators keep your vehicle running after the starter kicks over the engine
Alternators are rated in amps, so the more accessories you add with a higher draw (like an aftermarket sound system) the more powerful alternator you’ll need
Although underdrive pulleys help out supercharged Mustangs, the pulleys hinder your Mustang’s alternator. If you’re thinking about a new set of pulleys, don’t neglect your alternator
A weak alternator can put your electronics on the fritz, throw engine codes, make your lights flicker, and cause your Mustang to shut off while cruising down the road
Surplus energy isn’t a bad thing, so getting more amps than you need isn’t a bad idea
Your Mustang’s electrical system relies on the alternator to keep it running. Once the battery starts the car, the alternator takes over. It recharges the battery and keeps all the electrical components of the car juiced up and working properly. If your alternator is not working properly or is undersized for your needs, the car’s systems will not be working at their peak performance. This can lead to a poorly running vehicle and dimming or weakened accessories. On some Mustangs, a weak or faulty alternator can cause many electrical gremlins that result in incorrect trouble codes and diagnoses.
