Frequently Asked Questions

Q: How much do Lithium Ion batteries cost?

A: Lithium Ion cells are a relatively new technology, especially so in the formats of 40Ah and greater. Thunder Sky make some of the most cost effective batteries available. However the price is still 3 - 5 times that of Lead Acid. Any new technology requires time to grow the manufacturing capabilities and begin the automation that ultimately reduces the price.

However Lithium (phosphate) Ion batteries have up to 5 times the discharge cycle life of Lead Acid. They will also deliver almost their entire amp hour capacity at high rates of discharge. In EV applications Lead Acid batteries will barely deliver half of the rated amp hour capacity because of the Peukerts effect. This makes the total cost of ownership for Lithium Ion cells lower than Lead Acid.

Q: How long will they last?

A: They should last at least 1000 cycles at 80% depth of discharge (DOD). However much depends on how they are treated. A battery management system (BMS) is important. In terms of time it is unknown because this technology hasn’t been around long enough. However you can rest assured that rapid improvements are being made constantly.

Q: Do they require maintenance?

A: No they are completely maintenance free for their entire life.

Q: Lithium Ion Batteries can explode and catch fire can’t they?

A: Under normal circumstances with a good BMS no. However if ruptured of incorrectly discharged and charged the cells can die an early death and may catch fire because of the organic electrolyte. The LFP series are much safer then Lithium-Cobalt and Lithium-Manganese batteries.

Q: Thundersky also supply 12V batteries. Do they require a BMS?

A: The LP series are actually 4 LFP cells in one package. They do not have any management. For systems of more than 12V nominal individual cell management is recommended.

Q: Can the cells be mounted in any position?

A: Its best if they are mounted upright and all together in one pack. Engineer your vehicle around the batteries, not the reverse.
