Batteries & Charging
Can I connect batteries in series or parallel?
Yes, within the limits listed on each product page:
- Elite 12.8V 100Ah: up to 4 in series or up to 4 in parallel.
- Elite 12.8V 200Ah: up to 4 in series or up to 16 in parallel.
- Elite 25.6V 100Ah: up to 16 in parallel. For series connection, please contact support before wiring.
- Elite 51.2V 100Ah: up to 16 in parallel; series connection is not supported.
For any setup beyond these limits, email support@pathfinderer.com first.
Can I mix different batteries in one bank?
No. Only connect identical batteries (same model, voltage and capacity), ideally bought at the same time. Mixing capacities, ages or brands makes the cells charge and discharge unevenly, which shortens battery life.
How long does it take to charge?
A simple estimate is battery capacity ÷ charger current. For example, a 100Ah battery on a 20A charger takes about 100 ÷ 20 ≈ 5 hours from empty. Real times vary slightly with temperature and how deeply the battery was discharged. Check each product page for its recommended charge current.
Can I use my old lead-acid charger?
We recommend a charger with a LiFePO4 (lithium iron phosphate) charging profile, set to 14.2–14.6V for 12V batteries. A lead-acid charger without a lithium/LiFePO4 mode may not charge the battery fully or correctly, so we do not recommend it.
How should I store the battery?
For storage, leave the battery at about 50% charge, disconnect it from all loads, and keep it in a dry place. Top it up about every 3 months so it never sits fully empty.
What protections does the BMS provide?
Every Elite Series battery has a built-in intelligent BMS (battery management system) with always-on short-circuit protection, over-voltage and under-voltage protection, and temperature monitoring, plus built-in cell balancing. The batteries also self-heat when connected to external power, so they can charge in temperatures down to -20°C (-4°F).
Are the batteries safe to ship?
Yes. Our LiFePO4 batteries are UN38.3 transport-tested. A copy of the test report is available on request at support@pathfinderer.com.
Shipping & Delivery
How much does shipping cost?
