| Alternator size | 0 – 1.5m Cable Run | 1.5 – 4m Cable Run |
| 0 - 25 amps | 6 mm2 | 10 mm2 |
| 25 - 45 amps | 16 mm2 | 25 mm2 |
| 45 - 45 amps | 25 mm2 | 35 mm2 |
| 85 - 125 amps | 35 mm2 | 50 mm2 |
| 125 - 180 amps | 50 mm2 | 70 mm2 |
| 180 - 180 amps | 70 mm2 | 90 mm2 |
Please note that if there is a problem obtaining for example 90 sq mm cable, simply use 2 x 50 sq mm or 3 x 35 sq mm. The cable is simply copper, and all you require is the copper. It does not matter if it is one cable or 10 cables as long as the cross-section adds up. Performance of any product can be improved by thicker cable, so if in doubt round up.
The Alternator to Battery charger (A2B) connects very simply to an existing alternator(s) and provides extremely fast and effective charge to the domestic/house bank (5+ times faster than a stand alone alternator). The A2B achieves this performance by pulling down the voltage on the alternator by putting a ‘load’ on it. This low voltage (at high current) is amplified to a 4 stage charging profile at the domestic bank. Due to the A2B’s internal splitting system there is the option to charge the starter battery too. The starter does not get advanced charging, it simply gets a sufficient maintenance charge.
Features - Largest model up to 400A (at 12V), 200A (at 24V).
- Quick and Easy Installation. This charger is effective, simple and fast to install. It transforms the output of the alternator into a sophisticated multistage charger resulting in faster and more complete charging of your house / domestic battery bank.
- Starter bank and domestic bank charger. This charger has an intelligent integral splitting system. The output is split to the starter bank and to the domestic / house bank. Domestic receives advanced charging.
- Multiple alternator inputs. Numerous alternators can be fed to the input of the charger provided the total current rating does not exceed the charger’s rating. E.g. 400A charger can handle 4 x 100Aalternators.
- No alternator modification required. The charger is fitted between the alternator and battery(s) and, unlike conventional regulators, requires no modification or interference with the alternator whatsoever. This saves on time and bypasses any engine management systems (ECU) or warranty issues.
- Over 5 times faster charging. This charger optimizes the available output of the alternator and converts it to mimic that of a mains driven 4 stage battery charger. Consequently your batteries will charge faster resulting in less engine hours and a reduction in fuel used. This charger can therefore, pay for itself within a matter of weeks.
