FAQs

Every JRP traction pack uses LiFePO4 (lithium iron phosphate) cells. LFP is chosen over higher-density chemistries because its thermal runaway threshold is far higher, it contains no cobalt, and it holds capacity across a much longer cycle life - the right trade for vehicles that charge daily for years.

Only the charger matched to your pack architecture: 58.4 V for 48V packs, 69.4 V for 60V packs and 84 V for 72V packs. The current rating (6 A or 10 A) is matched to pack capacity. Using a charger with the wrong termination voltage is the single most common cause of pack damage.

The BMS monitors every cell group individually and terminates charging when the first cell reaches 3.65 V, rather than waiting for the pack terminal voltage to reach a target. That means no single cell can be overdriven even if the pack has drifted out of balance.

LiFePO4 chemistry in this configuration is rated for several thousand charge-discharge cycles to 80% of original capacity under normal use. Exact cycle figures for each model are being confirmed against internal test data.

Yes. JRP builds OEM packs to a required voltage, capacity, physical envelope and connector configuration. Send the vehicle specification, available battery-bay dimensions and expected duty cycle through the custom battery request form and the engineering team will respond with a proposed pack architecture.

Three years warranty and one year of free service on JRP lithium battery packs. Keep the original invoice and warranty card - both are needed to raise a claim.

Raise a service request with the pack serial number and purchase details. The pack is assessed at an authorised service centre; within the warranty period, covered faults are repaired or the pack replaced.

In most cases yes, provided the system voltage matches, the controller accepts the discharge characteristics and the pack fits the battery bay. Confirm the vehicle model with the technical team before ordering a replacement pack.

Store at 40-60% state of charge in a cool, dry place. Avoid leaving a pack at full charge or fully discharged for long periods - both accelerate capacity loss. Top up to the storage window roughly every three months.
