What we found
- Matched to 3 batteries: 12V 200Ah Deep Cycle AGM, 12V 100Ah Trolling Motor, 12V 20Ah Deep Cycle, by setting each maker's published figures against the other — neither names the pairing.
- 11 specifications are published for it, each with the source it was read from.
- No matching recall was found in the records this catalogue holds from 7 regulators.
Assembled from the evidence on this page. Every figure and count below is shown with the source it was read from.
Battery and charging
- Battery profiles it carries
- Five profiles, including lithium and a user-defined one
- Boost voltage, per chemistry
- AGM 14.6, Gel 14.2, Flooded 14.6, Lithium 14.4 V
- Float stage on lithium
- No float stage at all on the lithium profile
- Boost timer on lithium
- The two-hour boost timer does not apply to lithium
- Which batteries it will equalize
- Equalization is for vented and flooded lead acid only
- Temperature compensation
- None on lithium; -3mV/°C/2V on everything else

Battery care and safety
- Overvoltage shutdown, per chemistry
- 16.0 V on every chemistry except lithium, which is 16.4 V
- Temperature sensor and lithium
- Do not fit the temperature sensor to a LiFePO4 pack with a BMS
