I'm looking for a quality replacement battery for my home built 36 volt Heinzmann brushed motor ebike. My near 14 year old 10 ah Ping battery is no longer charging properly. The charger cuts out at its balance point but the voltage drops so quickly it almost immediately cuts back in. I haven't kept up with ebike battery manufacturers and it appears to be a minefield. Can anyone recommend a good suppiier that makes a genuine cell shrink wrapped pack and charger thats going to last a good few years please.

Looks like Greenlance only has 20 amp discharge. I need 30 amp max.
It depends on the battery size. I have a 36V 16Ah battery from them and that has a 30A BMS. I think the 13Ah battery is only 20A on the BMS. Looking at the website the 20Ah one is currently only £3.50 more than the 16Ah one without any discount applied.

Had it since December. Don't fast charge. Happy so far but I haven't taken it to pieces to check. I'm sure there is someone in here that has though.
