100 W
I have a UK street legal (250W nominal) pedalec, and 36V (10s) batteries for it. I'm planning on building two bespoke 10s batteries, and want to find a charger that allows me to control the charge current and final voltage. From all I read, I can prolong the pack life by charging at less than 1C, and to 80% capacity (with occasional 100% charges to balance the cells).
This advanced charger from LunaCycle appears to be just what I need: https://lunacycle.com/luna-charger-36v-advanced-210w-ebike-charger/
But... in it's listing it specifically states: "110v AC input for North America".
The picture of the charger on their web site shows "AC Input: 110/220 VAC -- F6A".
So I wrote to Luna asking if the charger could work in the UK on the 240V mains supply. They replied: "Unfortunately unless expressly stated on the listing our chargers only work with 120V outlets."
I've tried various combinations of Internet search phrases, but I cannot find an equivalent to this model that is sold outside the USA and rated for UK mains voltage. I really don't want to fall back on the only chargers I can find, which are the enclosed fixed Volt, fixed amp variety. I'm looking for more control over the charging process, but not so much control as the Charge Satiator provides, and I will be wanting two chargers.
My first question is to any UK member that has used a charger similar to the Luna model - basically does it work on the UK mains, or is there an alternative that can be sourced from the UK that will do the same job?
My second question is whether using a step down transformer (like this one https://www.amazon.co.uk/dp/B00H404YOC/?coliid=I3LKFPVEMAXAF0&colid=2WBPAIA5VDOW6&psc=1&ref_=lv_ov_lig_dp_it ) would work. I know these things are quite common on building sites where the trades need to use tools that they get from the USA. So I'm thinking that if I plug two Luna chargers into it, they will feel right at home. However - I've been wrong before!
Any thoughts on this appreciated.
Thanks
Ian
