Key features deep-dive — Redodo LiFePO4 battery
The Redodo LiFePO4 battery shines in a few focused areas: cells & BMS, cycle life, weight & energy density, expandability and charging. We’ll walk through each with practical recommendations based on the product claims and customer reviews.
Amazon data shows many buyers choose Redodo for vanlife and RV installs because of the low weight and Group form factor; customer reviews indicate runtime advantage vs SLA and ease of installation in existing trays. Based on verified buyer feedback, buyers also asked for clearer documentation and faster-charging options.
The subtopics below explain what the specs mean in daily use and include actionable steps for purchasing and installation.
Cells & 100A BMS — safety and protection (what the specs mean)
The listing says “Grade A cells” — that typically means cells sorted for capacity and internal resistance and should give better balance and longevity than mixed-grade packs. Grade A implies tighter matching between cells and better initial capacity retention; customer reviews indicate packs arrive balanced out of the box more often when manufacturers claim Grade A.
The 100A BMS provides multiple protections listed in the description: overcharge, over-discharge, over-current, over-voltage, overload, and short-circuit. Practically that translates to:
- Continuous safe discharge: up to ~100A (use as ceiling, not regular target).
- Short bursts: the BMS usually allows short surge currents above 100A for a few seconds (manufacturer wording varies).
- Voltage cutoffs: BMS will disconnect under severe over-discharge/over-voltage to protect cells.
Actionable steps:
- Install an inline ANL/bolt fuse sized for expected continuous current — e.g., 100A fuse close to the battery if you plan near-100A draw.
- Use the BMS 100A as the continuous maximum — design systems for 80% of that (80A continuous) for margin and longevity.
- On first charge, charge to full and verify resting voltage ~13.3–13.5V and that the BMS doesn’t cut out under load — test with a 20A load and observe behavior.
Cycle life & longevity — to cycles explained
The product lists a wide cycle claim: 4,000–15,000 cycles. That range reflects testing under different Depths of Discharge (DoD) and conditions. To translate to years: at full cycle per day, 4,000 cycles = ~11 years, 15,000 cycles = ~41 years. More realistic consumer math uses partial cycles.
Examples with concrete math:
- If you cycle the pack 50% DoD daily (typical for RV usage) and the cell spec corresponds to ~6,000 cycles at 50% DoD, that’s roughly years (6,000 / ≈ 16.4 years).
- If you cycle deeper (near 100% DoD) every day and only achieve 4,000 cycles, that’s ~11 years.
Compare to lead-acid: the listing cites cycles for SLA. Even the low-end 4,000 cycles is ~8x typical lead-acid cycles. Customer reviews indicate users replacing SLA with LiFePO4 see dramatically longer service life and lower total cost of ownership over 5–10 years.
Actionable longevity advice: keep cycles shallow where possible (20–60% DoD), charge to full regularly at correct voltage, avoid high-temperature storage, and maintain proper ventilation and temperature control to maximize life.
Weight, size & energy density — why Group matters
At 22.16 lbs and 59.37 Wh/lb, the Redodo 12.8V 100Ah pack is notably lighter than a typical 12V 75Ah SLA Group that often weighs ~40–50 lbs. The product claims it runs twice as long as a 75Ah SLA at identical dimensions with a 60% discharge; customer reviews back out that runtime advantage in real installs.
BCI Group form factor matters because many RVs, vans, and boats have pre-existing Group trays and hold-downs. Practical tips:
- Measure battery bay internal dimensions before ordering — confirm terminal orientation and space for wiring.
- Check terminal type (usually M6 or M8 studs) and order matching lugs; some buyers reported needing to buy new lugs or adapters.
Installation checklist (physical):
- Measure bay length/width/height and clearance for cable routing.
- Confirm terminal stud size and polarity orientation.
- Plan a secure mounting method (Group tray, straps, or bracket) and leave space for ventilation and BMS access.
Expandability & system design — series/parallel and scaling to 51.2V
The listing states the pack supports “series & parallel” connections and gives an example: × 12V 100Ah in a 4P4S arrangement to reach 51.2V 400Ah (20.48 kWh). Here’s the step-by-step math and wiring caveats:
How 4P4S math works:
- 4S: series sets to 51.2V (12.8V × = 51.2V).
- 4P: parallel of those series strings increases Ah (100Ah × = 400Ah).
- Total energy: 51.2V × 400Ah = 20,480 Wh (20.48 kWh).
Practical limits & wiring guidance:
- Always match batteries by age and state-of-charge; never mix new and old packs in series or parallel.
- Balance charging and periodic capacity checks are required when you scale past 2–4 units.
- Fuse sizing: fuse each parallel string at or slightly above expected continuous current per string (e.g., for 100A continuous per battery, fuse each at 120A to allow margin).
Cabling & fuse quick table (actionable):
- 100A continuous: use/0 AWG for runs >1 ft for low voltage drop (or/0 AWG for short runs); consult an electrician for long runs.
- 50–80A continuous: AWG–4 AWG depending on run length.
- Always fuse within 2″ of the battery positive post.
Charging, recommended settings & temperature notes
The manufacturer recommends 14.6V at 20A (0.2C) for a full charge in ~5 hours. That’s conservative and optimizes cell longevity. Amazon data and customer feedback indicate many buyers use 30–50A chargers or MPPT controllers to shorten charge time, but faster charging may slightly reduce cycle life if used constantly.
Practical charger settings:
- Bulk/absorption: 14.4–14.6V (use 14.6V if explicitly recommended).
- Float: avoid float >13.6V unless the battery manufacturer explicitly supports it — many LiFePO4 systems don’t require float the way SLA does.
- Equalization: not applicable for LiFePO4 as it is for lead-acid.
Temperature behavior:
- LiFePO4 charging below 0°C can damage cells — use a low-temperature cutoff or battery heater if you live in freezing climates.
- Install in a location within the manufacturer-recommended temperature range and avoid charging below freezing.
Actionable steps:
- Set chargers/MPPT to 14.4–14.6V bulk/absorb and disable aggressive lead-acid float settings.
- Consider a 30–50A charger if you require faster recharge and understand the life trade-off; otherwise use the recommended 20A charger for longevity.
- Add a low-temp cutoff or heater if operating below 0°C.
