## Description

Photonic Universe is proud to offer this 2A DC to DC battery charger, from the leading German solar electronics manufacturer, Votronic. This intelligent battery trickle charger is designed to automatically divert charging current from a battery with a constant source of energy (e.g. being charged by solar / mains/ alternator) to a second target battery. The target battery will be trickle charged at a maximum of 2A. This battery to battery charger can be easily integrated or retrofitted into any 12V system, allowing the user to transform a single battery system into a dual battery charging system. In a solar charging system, the charger allows an easy conversion from a single battery solar charging kit to a dual battery charging kit, without the need to upgrade the single battery solar charge controller to a dual battery model. Unlike split chargers, there is no need to implement any overcharge protection into the system, as this trickle charger will top up the target battery at a slow and steady rate, ensuring optimum safety for your batteries. This DC to DC battery charger is suitable for use with any 12V lead acid batteries, with a capacity of 50Ah or greater. It is not compatible with 24V batteries or a combination of 12V and 24V batteries. Specifications: - Nominal voltage: 12V - Charging current: 0-2A - Working temperature range: -20 to +40 C - Size: 90 x 60 x 38 mm, 52g. Includes a detailed user manual. Please contact Photonic Universe if you have any questions about this product.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Battery  unit
*by J***  on 2 June 2024*

Now this was very good wored well would buy this again easy to use thanks

### ⭐⭐⭐⭐⭐ Great bit of kit
*by G***H on 16 September 2019*

Fantastic not had a flat battery since fitting it

### ⭐⭐⭐⭐ Keeps spare batteries juiced.
*by D***E on 15 December 2018*

Does the job, trickle charges your battery from your other battery, I use it to keep spare leisure batteries topped up in the summer, when I'm not using all my solar output. Max charge current it 2a so it really is just to keep your batteries in condition and shouldn't be relied upon to fully charge a battery. (Unless you have 50 hours to wait!)
