While designing a recreational vehicle (including buggy’s, tugs and other utility vehicles), the biggest concern is the charging time, weight and space occupied by the battery. With our range of Lithium Ion battery packs (including Lithium Ferrous Phosphate battery), you will find a perfect combination of fast charging, long life, light weight and less space. You will find more usable AH capacity per Kg of battery as compared to traditional lead acid battery.
Do let us know your requirement and we can custom design as per your application.
Due to the higher energy density and the greater useable capacity, you will find that a Lithium battery pack is significantly lighter in weight and smaller in size than an equivalent capacity lead acid battery. Besides, if you factor in the 100% depth of discharge achievable with a LiFePo4 pack, you will need a pack about half the capacity of a corresponding lead acid pack. That’s a lot of savings in weight and space, therefore giving you the option of a much lighter and sleeker vehicle.
The acidic vapours from a lead acid battery often mean that you have special storage conditions in an actual usage condition. With a Lithium Ion battery, you no longer need to worry about venting thus making these batteries much more flexible in storage locations in installations.
If you have owned and used lead acid batteries, you will know that they will need periodic maintenance to check the electrolyte levels and that the terminals will corrode over time. Besides, the acid and the acidic environment will have a tendency to also corrode anything around unless proper care is taken. With a Lithium Ion battery pack, you will not need any maintenance done and the risk of corrosion is almost nil.
A Lead acid battery pack suffers from a significant voltage drop in the beginning and as it reaches about 40% capacity, the energy becomes unusable due to low voltage. With a Lithium Ion battery pack, the voltage drop in the beginning is relatively much lesser and the usable energy in the battery pack remains almost up to 100 percent of its capacity. This makes Lithium Ion battery pack a much better alternative to Lead acid battery packs especially where usable energy considerations are important.
Unlike Lead Acid batteries which need to be charged in 3 stages, Lithium Ion batteries can be bulk charged upto 100% at a very rapid rate. Where it takes about 6 to 7 hours for a lead acid battery to fully charge, it's not uncommon to find an equivalent Lithium Ion battery pack being charged in less than half the time. If your application involves quick turnaround between fully discharged to fully charged status, Lithium ion is the best solution. Imagine having to wait for a Lead acid battery to fully charge in about 7 hours while an equivalent Lithium Ferrous Phosphate (LiFePO4) pack charges fully in about 2.5 to 3 hours.
Lithium Ion batteries have a charging efficiency of 99%. That means, the loss in charging is just about or under a percent. Compare this with Lead Acid batteries which have a charge efficiency of only 85% (ie., the charging loss is approximately 15%). In applications such as solar storage, this would mean that you will need about 15% less panel area if you are using Lithium Ion battery storage.
The number of cycles which a Lithium Ferrous Phosphate (LiFePO4) battery pack can do typically is upwards of 2000 cycles as compared to Lead Acid batteries which normally do about 300 to 400 cycles before they start waning in performance. If you discharge the LiFePO4 battery to less than 80% of its capacity, the number of cycles you get go up significantly (normally in the range of 2500 to 3000 cycles and upwards). Where you will need to factor in a 5 to 6 times lead acid battery replacement in a span of 10 years, you will be looking at zero replacements with a LiFePO4 pack under normal use circumstances.
We have covered this earlier; but this needs to be emphasized further since many electronic engineers ignore the DOD efficiency of a Lithium Ion battery pack while designing their solution and go for the cheaper lead acid battery pack. Lithium Ion batteries are capable of being discharged up to 100% (in regular use recommended discharge is 80%). Compare this with Lead Acid battery packs which are recommended for discharge only up to 50%. Where you need a 100 AH battery back with lead Acid, you will only need a 50 to 60AH battery with Lithium Ion. Now calculate the cost and you will find that designing your application with a Lithium Ion pack is after all not so expensive.
