While trying out different battery systems we found that many of them exaggerated the milliamp/Hour ratings. These batteries are within 10% of the rating at which they have been given.
They also feature overcharge protection.
They do not have their own on/off switch as we found this was unnecessary and just added another element that could fail.
We have these batteries in 4 different sizes with the following weights and dimensions:
1800mAh (Thin): 145g (10cm x 5.5cm x 1.1cm)
1800mAh (Square): 145g (5.6cm x 3.8cm x 3.1cm)
3000mAh: 172g (7.3cm x 5.6cm x 2.2cm)
5000mAh: 265g (6.0cm x 5.8cm x 3.9cm)
15Ah: 725g (14.0cm x 6.5cm x 4.7cm)
Capacity: 1800mAh, 3000mAh or 5000mAh
Input power: DC 12.6V
Output: DC 12V
Over-charge / discharge protection: Yes
These Li-ion batteries are best charged with dedicated Li-ion Intelligent Chargers
The 15Ah has an overcharge protection up to 15A so can take a larger current draw
AC Mains intelligent chargers come with UK plugs and are available in a choice of:
No Charger – if you already have your own intelligent Li-ion battery charger
1A Charger – This will charge the Li-ion batteries at a max of 1A per hour
2A Charger – This will charge the Li-ion batteries at a max of 2A per hour
