Auxiliary Battery and BMS Service in Riverside, CA

LiFePO4 and AGM aux banks with BMS wiring, built and serviced for work van power.

We install and service auxiliary battery banks for commercial vans in our Yorba Linda shop. We build LiFePO4 or AGM banks, wire and configure the BMS, and set up DC-to-DC and shore charging so the system powers tools, liftgates, refrigeration, and telematics without touching the starting battery. A well-built bank keeps Riverside service vans working a full day between charges.

What this service includes

  • Aux bank sizing and secure, crash-safe mounting
  • BMS wiring and configuration
  • DC-to-DC alternator charging setup
  • Shore and solar charge integration
  • Low-temperature charging protection where needed
  • Fused distribution, shunt, and battery monitor
  • System photos and spec sheet for fleet files

Who this is for

  • Fleets upgrading from a single starting battery
  • Vans needing more runtime for tools and equipment
  • Vans with a BMS fault or a failed cell
  • Owners wanting a documented, monitored bank

Frequently asked questions

Why choose LiFePO4 over a second lead-acid battery?

Lithium gives far more usable capacity for its weight and size, charges faster, and lasts many more cycles. For a work van that means more runtime for tools and equipment before anything needs a charge.

Does an aux bank protect my starting battery?

Yes. Equipment runs off the auxiliary bank, not the starting battery, and a DC-to-DC charger refills it from the alternator as you drive. The van still starts even after a long day of tool use.

Can you fix a BMS that keeps cutting power?

Often yes. A BMS trips on over-current, a weak cell, or a wiring fault. We test the pack and connections, find the cause, and correct it rather than just resetting the fault.

Will you document the bank for our records?

Yes. We provide photos and a spec sheet of the bank and wiring, so the system is on file for insurance and for whoever services the van next.
