In this section we have compiled lithium ion battery facts, frequently asked questions, and tutorials. Thought of a frequently asked question we should add? Just want to talk about lithium? Our company headquarters is in Sparks, Nevada, just outside Reno. We love our great state so much we decided to use the state slogan as our brand name. Today Nevada is playing a pivotal role in revolutionizing energy storage, and Reno is at the epicenter of the l i-ion battery world.

We at Battle Born B atteries are honored to be in such great company, and we want to continue helping Nevada lead the charge in revolutionizing l i-ion batteries. Our batteries are safe. The BMS protects the cells against excessively high or low voltages, high currents, short circuits, and excessive heat or cold.

These are the most common causes of battery failures, and we have taken every precaution to mitigate these risks in all of our batteries. In addition, all of our cells are manufactured in a state-of-the-art automated facility, and each cell is cycled multiple times to ensure quality and consistency.

Li-ion batteries can be safer than lead acid batteries, which have no protection against ground faults. Our built-in BMS that protects against ground faults. We strive to include all the best safety features into our battery, and this is what makes us a leader in the deep cycle replacement market. We are constantly developing new innovations to increase safety in our batteries. The upfront cost of our lithium deep cycle battery is higher than a lead acid equivalent. But, when you divide that cost by the life of the battery, our LiFePO4 battery is already cheaper than a lead acid battery.

When cost and time associated with changing the batteries is factored in, you really save a bundle when you decide to install a Battle Born battery bank. Able to run 3, cycles, most people will have these batteries for 10 to 15 years. The voltage of this type of battery is very similar to an AGM and will work great with readily available system components for your RV, boat, or off-grid power system.Forums New posts Search forums.

The following table illustrates an example of a very strong relationship between two variables: variable Age (Adult vs.

Child) and variable Cookie preference (A vs.

200 amp bms

COOKIE: A COOKIE: B AGE: ADULT 50 0 50 AGE: CHILD 0 50 50 50 50 100 All adults chose cookie A, while all children chose cookie B. However, in real-life, relations between variables are typically much weaker, and thus the question arises as to how to measure those relationships, and how to evaluate their reliability (statistical significance). The techniques used to analyze simultaneous relations between more than two variables in higher order crosstabulations are discussed in the context of the Log-Linear Analysis module and the Correspondence Analysis.

The Pearson Chi-square is the most common test for significance of the relationship between categorical variables. This measure is based on the fact that we can compute the expected frequencies in a two-way table (i. For example, suppose we ask 20 males and 20 females to choose between two brands of soda pop (brands A and B). If there is no relationship between preference and gender, then we would expect about an equal number of choices of brand A and brand B for each sex.

The value of the Chi-square and its significance level depends on the overall number of observations and the number of cells in the table. Consistent with the principles discussed in Elementary Concepts, relatively small deviations of the relative frequencies across cells from the expected pattern will prove significant if the number of observations is large.

The only assumption underlying the use of the Chi-square (other than random selection of the sample) is that the expected frequencies are not very small. For further discussion of this issue refer to Everitt (1977), Hays (1988), or Kendall and Stuart (1979).

In practice, the M-L Chi-square is usually very close in magnitude to the Pearson Chi- square statistic. For more details about this statistic refer to Bishop, Fienberg, and Holland (1975), or Fienberg, S. The approximation of the Chi-square statistic in small 2 x 2 tables can be improved by reducing the absolute value of differences between expected and observed frequencies by 0.

For small n, this probability can be computed exactly by counting all possible tables that can be constructed based on the marginal frequencies.

Thus, the Fisher exact test computes the exact probability under the null hypothesis of obtaining the current distribution of frequencies across cells, or one that is more uneven. This test is applicable in situations where the frequencies in the 2 x 2 table represent dependent samples. For example, in a before-after design study, we may count the number of students who fail a test of minimal math skills at the beginning of the semester and at the end of the semester.

The Phi-square is a measure of correlation between two categorical variables in a 2 x 2 table. For more details concerning this statistic see Castellan and Siegel (1988, p. This statistic is also only computed for (applicable to) 2 x 2 tables. If the 2 x 2 table can be thought of as the result of two continuous variables that were (artificially) forced into two categories each, then the tetrachoric correlation coefficient will estimate the correlation between the two.

The coefficient of contingency is a Chi-square based measure of the relation between two categorical variables (proposed by Pearson, the originator of the Chi-square test).

Its advantage over the ordinary Chi-square is that it is more easily interpreted, since its range is always limited to 0 through 1 (where 0 means complete independence). Interpretation of Contingency Measures. An important disadvantage of measures of contingency (reviewed above) is that they do not lend themselves to clear interpretations in terms of probability or "proportion of variance," as is the case, for example, of the Pearson r (see Correlations).

There is no commonly accepted measure of relation between categories that has such a clear interpretation. Statistics Based on Ranks. Suppose we asked a sample of respondents to indicate their interest in watching different sports on a 4-point scale with the explicit labels (1) always, (2) usually, (3) sometimes, and (4) never interested.

Obviously, we can assume that the response sometimes interested is indicative of less interest than always interested, and so on. Thus, we could rank the respondents with regard to their expressed interest in, for example, watching football. When categorical variables can be interpreted in this manner, there are several additional indices that can be computed to express the relationship between variables.

Detailed discussions of the Spearman R statistic, its power and efficiency can be found in Gibbons (1985), Hays (1981), McNemar (1969), Siegel (1956), Siegel and Castellan (1988), Kendall (1948), Olds (1949), or Hotelling and Pabst (1936). Kendall tau is equivalent to the Spearman R statistic with regard to the underlying assumptions.

It is also comparable in terms of its statistical power. However, Spearman R and Kendall tau are usually not identical in magnitude because their underlying logic, as well as their computational formulas are very different. Siegel and Castellan (1988) express the relationship of the two measures in terms of the inequality:More importantly, Kendall tau and Spearman R imply different interpretations: While Spearman R can be thought of as the regular Pearson product-moment correlation coefficient as computed from ranks, Kendall tau rather represents a probability.
