  • 2,000 cycles at full discharge, up to 6,000 at a fifth of it

    HOW LONG WILL MY BATTERY LAST? The average lifespan of a Dakota Lithium Iron Phosphate battery depends on use. If the battery is used at maximum discharge (typically 1C) then the lifespan is typically 2,000 recharge cycles or roughly 5 – 10 years with regular use. When used at <0.2C discharge the lifespan increases, up to 6,000 recharge cycles.

Ingress protection
Somewhere between IP65 and IP67 — the manual does not say which

Unconfirmed

Use a battery box or battery tray that protects the battery from water (DL batteries are water resistant at an IP 65 to IP 67 rating depending on the battery, but terminals may corrode if repeatedly exposed to salt water, and sitting in standing water for extended periods is not recommended for batteries).

What the battery management system protects against
Cut-offs at 10V and 15V, plus balancing, short circuit and temperature

Includes active BMS protection Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.

Warranty, returns and support

What the warranty covers
11 years against defects — not against the pack wearing out

Dakota Lithium offers a 11 year manufacturer's defect warranty from the date of purchase. The average lifespan of a Dakota Lithium Iron Phosphate battery is 2,000 recharge cycles, or roughly 5 – 10 years with regular use that is appropriate to what the battery is designed for (see the specifications of the battery). This warranty does not cover negligence or misuse of the battery or normal wear and tear.

Whether the warranty transfers on resale
Original owner only; one exchange; accessories get 1 year

1 year warranty on all accessories & complimentary products (chargers, powerbox cases, volt meter, etc). Free lifetime technical support & free battery analysis. Warranty only applies to the original owner (non-transferable). Warranties can be used for an exchange of a component only once.

Certification claims

The maker's own safety claim
The maker calls them 100% safe and not prone to fire

Unconfirmed

ARE LITHIUM BATTERIES SAFE? Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries is not prone to exploding or catching fire due to the lack of oxide / oxygen in the LiFePO4 chemistry.

Devices documented to run on this

The figures below line up. Neither manufacturer states that this pack runs this device — that is our reading of what each of them published separately, not a claim by either of them or a test by us. Even where every stated figure agrees, these can still decide it:

  • A motor’s published draw is usually a peak, not the load it holds — the two numbers are not the same kind of quantity
  • A maker’s amp-hour minimum and their reserve-capacity minimum can give different answers about the same battery
  • Conditions attached to the chemistry, such as a speed limit for running on lithium
  • Whether the pack may be wired in series at all, where the device needs 24 or 36 volts
  • The charger, which both makers put conditions on and neither supplies
  • Case size, hold-down and terminal type — fitting the space is not being secured in it

Worth confirming with the manufacturer or a dealer before buying.

Compatible platforms

The motors this pack is documented to run are listed above. No boat, rig or other platform in this catalogue is listed as carrying it — that is a separate question from what it will power, and nothing is listed until a source answers it.
